Why do you need a carton printing slotting die-cutting machine?
Описание: Why do you need a carton printing slotting die-cutting machine? Why do you need a Carton Printing Slotting Die Cutting Machine?

And a variety of cutting sizes are available for your choice. If you make all kinds of box and printing products, you can choose a carton printing slotting die-cutting machine to help you. The search for a new Carton Folder Gluer Machine can be very daunting. There are many folder-gluer OEMs out there and each has different models, features and sizes designed for a variety of applications. When a finisher or folding carton manufacturer is in the market for an upgraded or new folder-gluer, there are several questions to ask in order to find the best fit for the market they are involved in or attempting to enter. Do you run paperboard or corrugated? The paperboard market includes folding paper cartons – sometimes referred to as just folding cartons. The corrugated market produces folding boxes that often are referred to as cardboard boxes. The folding/gluing machines for these two distinctive markets may look similar, but the design and structure of the machines are quite different. There are folder-gluers that will produce products using both of these substrates, but on a limited basis. In other words, if you wish to produce corrugated C flute boxes, don’t expect the same folder-gluer machine to produce 12-point folding paper cartons – at least not efficiently. The Box Stitching Machihne is one of the post processing equipment of the carton. The principle of the machine is the same as the principle of the common stapler, but the nail box machine is used as a pad for the carton. This series of products have the advantages of lightness, easy operation, good wear resistance, smooth sealing, safety and firm, and can reduce the strength of labor and improve work efficiency. It is widely used in the sealing of various cartons and calcium plastic boxes which need heavy articles or not easy to use sticky tape. What Is Rotary Die Cutting?The first question you're likely asking when deciding whether or not Rotary Die Cutting Machine is right for your project is what exactly it is. Many people haven't heard about the benefits that die cutting services provide, and that's okay! In this section, we're going to inform you about what exactly rotary die cutting is and how it can apply to your individual work. A die, generally speaking, is a tool used to cut material into a given shape. It usually is made of metal and can cut through surfaces like paper, fabric, adhesive, and leather to give it the desired shape. This creates many cuts of cloth or plastic that are identical in size and shape to one another. For example, if a shoemaker were trying to create a set of leather shoes that matched with one another exactly, he or she would use a die cut to cut the shape of the shoe out of a larger leather sheet. In fact, this is the way that die cutting started up as a common process back in the 1800s! This process takes place when using a die cutting machine. These machines can be operated by hand, meaning that the operator pushes a lever and the machine cuts through the material. In the present day, though, it's more common that the machine will be automatic. Single-facer The section of a corrugator which forms the corrugated shape in the medium, applies adhesive to it and then bonds it to the flat linerboard. The output from a single-facer is referred to as Single Facer board. Most corrugators have more than one single-facer to enable different flute sizes to be used.

What is a pH Meter and how does it Work?
Описание: What is a pH Meter and how does it Work? pH is a measurable parameter between the values of 0 and 14, provided the concentration of the solution does not exceed 1M. Solutions with a pH7 are alkaline. A PH METER is a device that measures the changes in the activity of hydrogen ions in a solution. pH meters are electronic devices comprised of a special measuring probe (a glass electrode or, an ion-selective field-effect transistor (ISFET), in specialized cases), attached to an electronic meter that displays the decimal pH reading. The Automatic Calibration PH Meter must be calibrated prior to use against buffer solutions of known hydrogen ion activity. The standard methodology for measuring pCombined PH meters consist of a glass electrode made of a specialty glass membrane that is sealed at the end forming a bulb. Inside the glass is an internal standard acidity solution, usually 0.1 M HCl, along with an internal reference electrode, REin (typically an Ag/AgCl wire electrode). This solution is called the reference solution of known pH, 7. A second electrode REext is placed in an external tube immersed in KCl. This external tube forms a concentric enclosure around the first enclosed glass tube containing the 0.1 M HCl (the internal tube). The external tube is made of pH-sensitive glass and is in contact with the test solution through an opening called a porous diaphragm. The inclusion of a reference electrode encased by the internal tube is necessary as its pH is known and can be compared to a test solution so that its pH value can be determined. This set-up is called a combination pH electrode. The 3 in 1 PH Meter operates like a voltmeter. The pair of electrodes in the combinatorial set-up can measure small changes in voltage (also called potential difference) in the order of millivolts. Changes in potentials are caused by the loss of electrons that correspond with the loss of H+. The pH meter should be calibrated before each measurement using at least two standard buffer solutions of known pH values (typically around 4 and 7). A TDS Meter is a small hand-held device used to indicate the Total Dissolved Solids in a solution, usually water. Since dissolved ionized solids, such as salts and minerals, increase the conductivity of a solution, a TDS meter measures the conductivity of the solution and estimates the TDS from that reading. TDS meters may be referred to as TDS testers or PPM (parts per million) testers, but all of these are different names for the same thing. TDS meters can be purchased for as low as $10, but more advanced models can cost $1,000+ based on the level of accuracy and additional features offered. For example, a basic TDS meter may only measure the amount of total dissolved solids in a solution while an advanced model may be able to check salinity, temperature, and more. DO Meters use an electrochemical, polarographic, amperometric, galvanic, or optical sensor to measure the amount of gaseous oxygen dissolved in a water sample. DO is an important water quality parameter that effects marine life, the taste of drinking water, and the corrosiveness of a water sample. Common applications include groundwater remediation, wastewater, aquariums, and fish hatcheries. Salt Meters are an easy-to-use water quality indicating tool and are a great way to obtain a quick estimate of the dissolved salt present in a wide range of water samples. They are useful in a wide range of applications from testing salinity levels in water used for agriculture, drinking water, wastewater, and for testing the water in home pools and spas. If you have an interest in knowing how a salinity meter works, this article is for you.About Salinity MetersSalinity Meters are devices that are used to measure the amount of salt present in a substance. You can purchase salinity meters either on their own or as a sensor in multiparameter meters, which can measure other water quality parameters such as pH, conductivity, TDS and more. The inner workings of salinity meters may seem complex, but they produce accurate salinity measurements in a matter of seconds. When looking for a salinity meter, it is important to check whether the units of measurements are suitable for your requirements and choose a device with automatic temperature compensation (ATC) to make measuring faster and easier.

Your guide to granite, marble, quartz, and other countertop materials
Описание: Your guide to granite, marble, quartz, and other countertop materials Kicking off a kitchen remodel? You have a lot of work—and decisions—ahead of you. You’ll need to pick out new cabinets, floors, appliances, and more. Yet, the most impactful decision, by far, will be your choice of new countertops. There are so many options, styles, and colors to choose from. For many homeowners, finding the right countertops for their kitchen remodel is one of the most challenging parts of the project. In this article, we’ll guide you through your many Countertop & Vanity options and help you decide which material—granite, quartz, marble, stainless steel, or butcher block—is right for your kitchen. We’ll weigh the pros and cons of each, and make the case for how each might figure into your kitchen remodel. When most people hear “stone countertops,” they instinctively think of granite. It’s the definitive material for most kitchen remodels (although, as we’ll discuss, quartz is a close second and preferred by many people!). Cut from natural stone and then sealed, Granite countertops are incredibly durable and beautiful. They’re difficult to damage and, unsurprisingly, retain their value for many years because of this quality. Granite countertops come in two types: slab and prefabricated. Both are natural stone. “Prefabricated” just means the stone has already been cut to a default size prior to arriving at the distributor. Because of this one-size-fits-all approach, it’s generally cheaper than granite slab, which has not yet been cut or fabricated to size. If you’re working on a highly custom kitchen remodel, you may need to buy granite slab so that your contractor can customize not only the size, but also the edging and other details. If you love the look of natural stone, it’s hard to go wrong with Chinese Granite. For the reasons we’ll discuss below, it’s a better natural stone alternative to marble for kitchen remodeling projects. Durable: Granite is a tough material that can stand up to accidental slashes, cuts, and impact. Heat-Resistant: Granite is highly heat-resistant, which means you can put hot pans or trays on its surface without causing permanent damage. Unique: No two pieces of granite are exactly the same, which means your kitchen’s granite slab will truly be one-of-a-kind. When stone countertops first came into vogue, granite was the obvious choice for many homeowners. However, in recent years, an alternative—Quartz Countertops—have really taken off. Unlike granite, which is cut from natural stone and then sealed, quartz is real stone that has been processed and sealed into a protective resin. As a result, quartz countertops can look like just about anything: they can take on patterns, colors, and looks just not found in natural stone. Generally speaking, Quartz and granite countertops are about even in terms of cost. If you’re comparing the cost of quartz and granite countertops, you’ll really need to look at the specific countertops in question: both occupy the same average price range. Another place the two materials are just about even is their overall durability. Quartz trades the heat-resistance of granite for better moisture and leak resistance. They’re both very solid and stand up well to everyday use. The final verdict? The choice between quartz and granite is less about specifics and more about your personal taste and what your kitchen remodel needs. If you’re looking for the strength and beauty of natural stone, granite is probably right for your kitchen. If you want a more modern design, quartz probably has something you’re looking for. Variety: Quartz countertops are available in far more colors and design variations than granite or marble, which means they work with more kitchen styles. Maintenance-Free: Unlike granite, quartz countertops come sealed in a permanent resin and do not need to be regularly resealed. Durable: While not invulnerable, quartz stands up to everyday wear-and-tear and is stain-resistant. If you want to add class, elegance, and luxury to your home, Marble countertops are the right material. After all, there’s a reason marble was the medium of choice for Renaissance sculptors. It has a timeless beauty and radiance to it. By adding marble to your kitchen, you’re not just choosing a countertop. You’re making a statement. However, there are some drawbacks that should make you reconsider your decision to put the marble in your kitchen. Besides its high cost (discussed below), marble is also the least durable of the three stone countertop options discussed in this article. It just doesn’t stand up to everyday cooking and cleaning in a kitchen. For homeowners with their hearts set on adding marble to their home, we recommend using it for bathroom vanities and remodels, where there’s not as much pressure on homeowners to protect the stone. If you’re comparing the cost of marble versus granite or the cost of marble versus quartz, you’ll find that, generally speaking, lower-end marble costs more per square foot than high-end granite or quartz. According to data from HGTV, the average cost of granite, per square foot, is $75. Meanwhile, the average cost of marble countertops starts at $100 / square foot and can actually be as much as $200 / square foot! In general, it’s more expensive to install and—the larger your kitchen—the more your costs will ballon if you opt for marble. Luxury: Marble Slabs are considered the material of choice for luxury condos and home builds. It’s beautiful, and the right marble countertop is a true showstopper in any kitchen.

Monitor Stands Make Your Work Setup More Comfortable
Описание: Monitor Stands Make Your Work Setup More Comfortable A Monitor Stand is a work from home essential that serves two important purposes: Giving you extra space for your accessories, cleaning off your desk, and making your workspace more ergonomic. By elevating your monitor closer to eye-level you won’t have to crane your neck for hours at a time, which can strain it over time. We’ve had hands-on testing time with a number of monitor stands, and collected the ones that are worth your time in this guide. All of these stands will work with any monitor, regardless of its size or who makes it. You can also use these stands to elevate a laptop — PC or Mac — or a monitor and computer if the stand is large enough. If your neck is sore at the end of each work day, or you want a little extra storage space on your desk, these are the monitor stands we recommend. There are many factors to consider when choosing the best Monitor Stands for you; below are the most important ones, which we considered while we were researching this list. Size: The monitor stands we’re recommending are between 10 and 46 inches wide; larger ones are better if you want to fit two monitors, while smaller ones are better for compact desks. Elevation: The monitor stands in our guide are between 2.19 and 8.5 inches tall — think about this when deciding how high your monitor needs to be for optimal comfort. If you use an Adjustable Stand, you’ll have more flexibility. Materials: All of the monitor stands we’re recommencing are made out of wood or metal, so they’ll add a nice aesthetic quality to your home office. Additional Space: One of the biggest advantages of using a monitor stand is the ability to use space below the stand for storage. Every monitor below offers some level of storage for accessories, so you can clean up your desk. If we can’t adjust our monitors, we adjust ourselves and our posture to the position of our screen. We hunch. We crane our necks. And in computer intensive roles, we do this for long periods of time. This leads to eye, neck and back strain, which in turn leads to musculoskeletal disorders, time off work, and ultimately a loss in productivity. This is where an adjustable Pos Stand is key. If a person can adjust the height, distance and angle of their monitor it means they can adjust their technology to their own unique requirements. Reducing the occurrence of eye, neck and back strain. At home, or in the office, using a Tablet Stand is a practical solution to free your hands and comfortably read multimedia content. But still, most people are not aware of their alluring benefits. Also, this accessory is available in such a wide variety, that it can be tricky to find the one that suits your needs. Viewing a tablet screen on a flat surface or haphazardly propped up on something is both uncomfortable and annoying, while having to hold it up at a certain height gives you dead arms. A tablet desk stand offers you comfort and even saves you from neck, arm, and back pain. If you’re using both hands to type on your Macbook but still want to use your iPad to view something, then a tablet stand could prove helpful. A desktop stand can improve productivity once the tablet is at the same level as your computer, as you can easily switch between tasks. How to Choose the Right Tablet Desk Stand? While you might have an idea about what kind of tablet stand to get, you can still be overwhelmed by the options out there. So what factors do you need to consider when selecting a suitable stand? Here’re a few tips to help you make up your mind. 1. Size It’s not just about how big the TV Stand is but more about the size of the tablet it supports. Tablet stands come in different shapes and sizes. Some are larger with more features and tend to be sturdy static desk stands capable of holding bigger tablets, whereas, portable stands may only hold smaller-sized ones. If you have multiple tablets, or you’re sharing the stand with your family and colleagues, it’s better to buy one that holds tablets of varying sizes and weights. 2. Flexibility There may be times when you want to rotate your tablet between portrait and landscape mode or alter the angle of your screen. With a tablet stand that allows you to adjust the device, you can easily switch to Facetime from a movie. If you’re using the tablet to give a presentation, it’s a lot easier to show everyone what’s on the screen. 3. Height How do you want to access the tablet? There are ARM Stands of different heights for different purposes. If you want to use your tablet while standing, choose one that allows you to look at the screen at eye level. To use a tablet stand at your work desk, make sure it lets you comfortably use the tablet. 4. Location Where will you put the tablet desk stand? Is it part of your office setup, or will you use the tablet in the kitchen so you can look at recipes while you cook? Some tablet holders sit on a flat surface, while some need fixing down using stickers or screws. 5. Durability You don’t want to see your tablet falling off when you rotate the screen, so make sure the stand is sturdy enough not to tip over easily. Many stands have clips or stickers holding the tablet in place on the mount.

Our In house manufacturing facility ensures timely delivery and control. What are the advantages of AAC blocks? In today’s times when the world is realising the importance of environmental conservation, the construction sector has also witnessed technological advancements, including the use of innovative and sustainable construction materials. Here are some of the advantages of AAC bricks: Better workability and faster construction AAC blocks are about 50% lighter and 10 times larger than traditional bricks. This unique property facilitates easy installation and gives the desired flexibility that makes adjustments, cutting, shaping, etc., quite easy. AAC Block Production Line has fewer joints and consistent dimensions, thereby, ensuring ease of laying and making the construction process faster. Lastly, the lightweight blocks are easy to transport, which helps to save on the overall logistics and shipping costs, as compared to the costs involved in the transportation of traditional bricks. Earthquake-resistant Generally, buildings are designed to handle vertical forces, such as self-weight and gravity. However, there are also horizontal forces, such as those caused by earthquakes. The AAC blocks gain a high level of strength during the manufacturing process, giving durability to the finished structure. Thus, structures made with AAC bricks are capable of handling higher seismic loads, compared to structures with conventional bricks. Thermal insulation and energy-efficiency The material contains small air pockets and hydrogen is used to foam the concrete, thus, giving it an excellent heat insulation property that allows temperatures to be warm in winters and cool in summers. Therefore, it can significantly lower your air-conditioning costs by about 25%. AAC blocks are energy-efficient across their lifecycle, as their production involves less energy consumption. Fire-resistant The AAC Production Plant is non-combustible and provides fire resistance of up to six hours, depending on the block thickness and up to 1,200 degrees Celsius, compared to other building materials. Thus, it also has importance from a fire safety point of view. Sustainable and affordable AAC blocks are made from natural and non-toxic raw materials and their manufacturing process generates minimum waste. Some of the waste or offcuts generated can be recycled or used in aggregates. As it is made from non-biodegradable materials, it makes the building durable and stable, preventing rot or mold. Furthermore, being lightweight, energy-efficient and easy to install, AAC blocks also minimise labour costs.

Описание: The Best Skin-Care Tools and Devices to Try at Home Over the past few years, technology and skin care have collided more than ever before, causing us to wonder: Could there soon be a day when all our precious serums and creams will be rendered obsolete, replaced by a bevy of high-tech tools and devices? The short answer is probably not. No product-obsessed person would ever dare say "see ya later" to their beloved top shelf, but that's not to say the aforementioned gadgets won't seriously upgrade the skin-care game — and potentially shake up the industry as we know it. Need proof? We have a Food and Drug Administration-cleared LED mask that'll help reduce the appearance of wrinkles and fight acne and a vibrating facial massage tool that mimics your body's natural lymphatic system. Oh, and there's an epidermal growth factor (EGF) Micro-Needling + Ion Infusion Kit from Georgia Louise to consider as well — which creates tons of tiny channels on your skin's surface. The tech-based options we're exposed to seem to be increasing by the month, let alone year, so we've rounded up 17 dermatologist- and editor-approved skin-care Facial Device worth trying out this year, including a handheld LED light that literally zaps away the appearance of fine lines over time. Massage guns, also known as percussion Massagers, percussive therapy and vibration therapy, offer many of the benefits of massage without the expense or the hassle of a visit to the massage therapist — something currently forbidden, with physical distancing. These electric tools, which start at about $100 and resemble power drills, deliver a vigorous massage and typically come with a selection of attachments, such as balls of varying firmness and finger-like tips, and have different settings. While they’re designed to be used by anyone, they’re most popular among endurance athletes such as triathletes and ultramarathoners, says Hugh Williams, the marketing director of Addaday, a massage gun manufacturer. But with the benefits come a few risks as well. Here’s what you should know before using one. Like a traditional massage, the Body Hair Device aims to reduce inflammation by flushing extracellular fluids such as lymph fluid and venous blood out of the muscle tissue and into the circulatory system. It can help relax tight muscles, break up scar tissue and adhesions, and minimize muscle soreness and tension. A small study published in the Journal of Clinical and Diagnostic Research found percussive therapy to be as effective as massage in preventing DOMS (delayed onset muscle soreness). Unlike with many other forms of bodywork, it’s not only possible to perform percussive massage on yourself but it’s recommended. According to Alan Novick, physician and chief of the Memorial Rehabilitation Institute in Hollywood, Fla., if someone else is using the gun on you, regardless of their credentials, skill and experience, they can’t tell how much pressure they’re exerting on your body or how much pain you might be experiencing as a result. “You could actually hurt somebody,” he says. On the other hand, if you’re using it on yourself, “you have that direct feedback loop and you’re not going to apply as much pressure,” Novick says. During the 1940s, many hospitals began utilizing UV-C energy for the control of airborne infectious diseases. With the arrival and proliferation of antibiotics, use of germicidal UV began to wane. During the 1990s, drug-resistant “superbugs” and hospital-acquired infections renewed interest in UV-C, which can kill virtually any microorganism, including antibiotic-resistant germs. ASHRAE has recognized that the UV-C wavelength inactivates virtually all microorganisms living on HVACR surfaces, with kill ratios of up to 99 percent, depending on the intensity of the UV-C and the length of exposure.6 UV-C dose is determined by the amount of germicidal energy a pathogen absorbs over a specific period of time. In other words, UV-C dose is a function of time multiplied by intensity. Consider, for example, a surface-disinfection application involving cooling coils. The Disinfection Device target (the coil surface) is stationary, so exposure, or “residence,” time is continuous. As a result, the intensity of the UV-C energy striking the surface can be relatively low. In the case of a moving air stream, however, exposure time is limited—a mere fraction of a second, in some cases—so UV-C intensity must be much greater. It is important to note that microbe inactivation is a nonlinear function of UV-C exposure. In other words, “If a certain UV exposure kills 90 percent of a bacterial population (frequently referred to as ‘one-log kill’), doubling the exposure time or intensity can kill only 90 percent of the residual 10 percent, for an overall germicidal efficacy of 99 percent (‘two-log kill’).”

Alloy Steel: Everything you need to know about alloy steels and their role in building and construction industry
Описание: Alloy Steel: Everything you need to know about alloy steels and their role in building and construction industry Steel is among the most popular materials used in the construction industry. According to the World Steel Association, in 2018 around 1,808 million tons of crude steel was produced worldwide and about 50% of this production was utilized by the construction industry. Further, they also state that there are as many as 3,500 different grades of steel and each grade offers environmental, chemical and physical properties unique to that grade of steel. Steel has undergone significant evolution through time and around 75% of all the types of modern-day steel were developed in the past 20 years. It is interesting to note that had the Eiffel Tower (constructed in 1887) been constructed in today’s times, it would require only one-third of the steel used back then. There are two kinds of alloy steel – low-alloy steel and high-alloy steel. As mentioned earlier, the composition and proportion of alloying elements determine the various properties of alloy steel. Low-alloy steels are the ones that have up to 8% alloying elements whereas high-alloy steels have more than 8% alloying elements. There are hundreds of products that can be manufactured with alloy steels of varying compositions. These include Stainless Steel Pipe/tubes, alloy steel plates, sheets and coils, alloy steel bars, rods and wires, alloy steel forged fittings, alloy steel buttweld fittings, alloy steel flanges, fasteners and more. Alloy steels have many uses in various industries such as automobiles, mining, machinery and equipment, railways, road construction, buildings, appliances and off-shore applications. Alloy steel flat products Alloy steels are used to make flat products – plates and strips. Plates are available in a wide range of grades and sizes. These are used in building construction by welding plates into fabricated sections. Alloy steel strip and coil products Strips are available as hot and cold rolled strips and hot-dipped galvanized Stainless Steel Coils. Hot-dipped galvanized coils are used to make construction products that include wall and roof claddings, side rails, roof purlins, light steel frames and lintels. Alloy steel long products Alloy steels are employed in producing long products used in the construction industry such as girders, structural sections, Stainless Steel Bars, rails, rods and wires. Alloy steel pipe products Alloy steel pipes are important materials in the building and construction industry because of their performance characteristics such as ductility, ease of fixing without heat treatment and high durability. They are an Inconel Alloy of stainless steel, chromium and nickel. Some special types of alloy steel pipes include large diameter welded pipes, electric fusion welded pipes, welded pipes and seamless pipes. They are extremely useful for high-temperature or corrosive applications besides high-pressure environments. Applications in building bridges Bridges use special Nickel Based Alloy steels known as weathering steels. These provide enhanced protection from corrosion because of the presence of nickel, copper and chromium as alloying elements. Weathering steels also find uses in buildings as facing material to improve aesthetics. Weathering steel offers several benefits which include high safety, ease and quickness of construction, aesthetic looks, shallow depth of construction, low maintenance and amenable to alterations in the future. Because of its natural weathered finish, no painting is required thus avoiding environmental issues caused by paints. Weathering steels are extremely cost-effective in the long run. When we talk about materials with wide applications in the construction business, home, power, and architecture, one material that comes to mind is stainless steel. No doubt, stainless steel has many applications in the modern world. However, there are many things people don’t know about it. We all can say that there are many cutleries made of stainless steel. However, not many people know about the different stainless steel types used in making many products used by people. What is Stainless Steel? One of the common metals with different applications in many sectors is stainless steel. Stainless Steel Sheet has many properties that make it ideal for such a purpose. For example, it is anti-rust and anti-stain. Stainless steel was accidentally obtained due to the addition of Chromium to Iron. When compared to other metals and alloys such as Iron and Steel, it has other advantages. Here, you will know about the properties of the three, their relationship, and their differences. Unlike what most people know, stainless steel is not a single entity. Instead, it is a single broad entity that encompasses many things. Stainless steel is an alloy that contains at least 11% chromium. Due to this composition, stainless steel does not rust, and it is heat resistant. Depending on the stainless steel types, you can have other elements such as carbon (0.03-1.00%), nitrogen, silicon, sulfur, niobium, and molybdenum.

Adjustable Feet give you the freedom to move up and down, which helps with blood flow and increases circulation. The long-term effects include an overall decrease in the risk of cardiovascular disease as a result. You can even burn calories! I mean, we’re only talking about an extra 10 calories per hour or so, so it’s not exactly going to replace your regular gym workout regimen. It’s not exactly going to be the cover story in the next health magazine center spread as the secret to weight loss, but hey, every little bit helps! And it promotes healthy habits that could lead to more energy and more motivation to move from the work desk to the weight room. Baffle Grease Filters are the initial step to managing commercial kitchen grease and regulate exhaust ventilation. When installed properly, they safely guard the exhaust vents to keep flames or flammable debris from entering the ducts, and they capture grease vapors and particles to prevent them from building up in the ventilation system. These filters come in a wide variety of sizes and dimensions, and can be made from high quality stainless steel, galvanized steel, or aluminum. These standard filters can be welded or riveted, while some speciality filters may be constructed differently to serve their specific purpose safely and efficiently. When you cook on a stove or using other methods, smoke, steam, and grease are released into the air. The interlocking baffles of the filter channel this air by simultaneously forcing it in two different directions, passing it through the strategically placed vertical blades and causing the grease to naturally run downward and into the designated collection trays within the casing, sanitizing the air. This prevents major fire hazards and is required by the National Fire Protection Association (NFPA), International Fire Code (IFC), and insurance providers, and is heavily enforced by health inspectors and fire marshals. Mesh hood filters are no longer accepted or allowed under the newest fire codes, so be sure to find the right size and material Range Hood Filter for your kitchen to comply with the current standards. Stainless steel filters are often the best choice for their aesthetic appearance if your kitchen is visible to customers because of their shine and reflective finish. They also offer the maximum protection against corrosion and rust. Galvanized options are also available, and depending on the volume and use of your kitchen, the lighter weight and less expensive aluminum filters may be considered as well. Of these three options, stainless steel will be more expensive, but their durability and their lasting capability can help save you in replacement costs in the future. Baffle Grease Filters should fit the exhaust with no gaps or spaces between them to prevent grease and debris from passing through. It may be helpful to have a local professional test your system and adjust the settings correctly to avoid turning the exhaust fan up too high. This is to prevent your filters from getting sucked up into the hood. While the most important function of a baffle grease filter is to prevent fire hazards and adhere to fire, health, and safety codes, they are also beneficial to utility costs, kitchen cleanliness, and the exhaust system itself by easing the strain on the motor. It also keeps the air properly filtered and sanitized, which results in a cooler kitchen and healthier breathing environment. In addition, it removes odor build up that could give your kitchen a stale smell. Traditionally, most homeowners have two choices for the stove: gas and electric. More often than not, the type of stove you prefer boils down to what you learned to cook on. However, conversions occur, and plenty of people find reasons to switch their allegiance. For instance, burgeoning chefs may be swayed by the versatility and accuracy provided by the flame heating of gas stoves. Meanwhile, parents with young children may switch to an Electric Stove, seeing it as the safer of the two. Families also appreciate the easy-clean virtues of electric stoves. Strong as one’s personal preference may be, economics play a role too: Depending on where you live, one or the other stove type might be cheaper to operate. A dry ESP （Eletrostatic Precipitator） electrically charges the ash particles and imparts a strong electric field in the flue gas to collect and remove them. An ESP is comprised of a series of parallel, vertical metallic plates (collecting electrodes) forming lanes through which the flue gas passes. Centered between the collecting electrodes are discharge electrodes which provide the particle charging and electric field. This figure shows a plan view of a typical ESP section which indicates the process arrangement. A transformer-rectifier (T-R) set along with an automatic voltage controller (AVC) supply the high-voltage and unidirectional current to the discharge electrodes. Several T-R sets are normally required to power a precipitator.

Polyethylene film
Описание: Polyethylene film What is polyethylene film? PE Film is a plastic film made from ethylene, a hydrocarbon which is mainly obtained from natural gas or petroleum. The terms ‘plastic sheeting’, ‘polyethylene sheet’, ‘poly sheeting’ or ‘poly film’ are often used as synonyms for polyethylene film.The term polyethylene is abbreviated as ‘PE’, the same way polystyrene and polypropylene are abbreviated as ‘PS’ and ‘PP’ respectively. In the United Kingdom, the word ‘polythene’ is often used instead of ‘polyethylene’. PE Protective Film can be made of different types of polyethylene. The most sold types of polyethylene are: Low-Density Polyethylene (LDPE). High-Density Polyethylene (HDPE).Linear Low-Density Polyethylene (LLDPE).Polyethylene film can also be manufactured in different colours or be transparent. In addition, it can be purchased in different thicknesses. Aluminum Foil is a common household product that’s often used in cooking. Some claim that using aluminum foil in cooking can cause aluminum to seep into your food and put your health at risk. However, others say it’s entirely safe to use. This article explores the risks associated with using aluminum foil and determines whether or not it is acceptable for everyday use. Aluminum foil, or tin foil, is a paper-thin, shiny sheet of aluminum metal. It’s made by rolling large slabs of aluminum until they are less than 0.2 mm thick. Commercial Aluminum Foil is used industrially for a variety of purposes, including packing, insulation and transportation. It’s also widely available in grocery stores for household use. At home, people use aluminum foil for food storage, to cover baking surfaces and to wrap foods, such as meats, to prevent them from losing moisture while cooking. People may also use aluminum foil to wrap and protect more delicate foods, like vegetables, when grilling them. Lastly, it can be used to line grill trays to keep things tidy and for scrubbing pans or grill grates to remove stubborn stains and residue. Cooking With Aluminum Foil May Increase the Aluminum Content of Foods Most of your aluminum intake comes from food. However, studies show that aluminum foil, cooking utensils and containers can leach aluminum into your food. This means that cooking with Household Aluminum Foil may increase the aluminum content of your diet. The amount of aluminum that passes into your food when cooking with aluminum foil is affected by a number of things, such as: Temperature: Cooking at higher temperatures Foods: Cooking with acidic foods, such as tomatoes, cabbage and rhubarb Certain ingredients: Using salts and spices in your cookingHowever, the amount that permeates your food when cooking can vary.For example, one study found that cooking red meat in aluminum foil could increase its aluminum content by between 89% and 378%.Such studies have caused concern that the regular use of aluminum foil in cooking could be harmful to your health. However, there is currently no strong evidence linking the use of aluminum foil with an increased risk of disease. What Is Blister Packaging?PVC Blister packaging is widely used across the pharmaceutical industry as a unit-dose packaging solution that helps people take the correct amount of medication at the right time. Blister packaging is made using several types of rugged polymers, including: Polyethylene terephthalate (PET)Polyvinyl chloride (PVC)Polyvinylidene chloride (PVDC)Polychlorotrifluoroethylene (PCTFE)Cyclic olefin polymers (COP)Blister packaging is manufactured from a plastic sheet that is thermoformed to create cups or blisters that hold a product in place. The packaging typically has a paperboard backing or a lidding seal of aluminum foil or plastic film. Blister packs provide a safe, secure way to ship medicines and small consumer items, offering additional protection when goods are transported inside custom cardboard boxes. Each type of material used to create blister packaging offers something different. Obviously, size is an important consideration when buying Laminated Composite Film. You will need to know how wide your machine is and then buy film that’s compatible with that width. You will also need to think about the size of the document you plan on laminating. For example, if you’re laminating letter-sized items, you can use film that’s 12 inches or wider and trim away the excess. The length of the roll isn’t as important as the width, so you don’t need to worry too much about that. Just make sure the roll isn’t too long for your laminator. Thickness is an important factor when choosing laminating film. If you read your machine’s instructions, it will tell you what thickness the laminator can handle, whether it’s something on the lower end of the scale such as 1.5 mil film or something thicker, like 10 mil laminate. The higher the mil number, the more rigid your laminated document will be. Keep in mind that a lot of school laminators can only handle the thinner films, such as 1.5 and 3.0 mil film.

New to the Mining Industry? Make Sure You Know the Most Common Types of Mining Equipment
Описание: New to the Mining Industry? Make Sure You Know the Most Common Types of Mining Equipment Working in the mining industry can be a dangerous place if you don’t know what you’re doing. Regular training is essential and understanding the machines you’re working near or operating plays an important role in all aspects of the industry. Each type of mining equipment comes with its own set of mining activities. The most common types of Mining Equipments and Parts vary depending on whether the work is being carried out above or below ground or mining for gold, metals, coal or crude oil. From drilling machines to excavators, crushing and grinding equipment – the mining industry comes complete with all the right tools. New to the job and want to find out what it all means? Here’s a few of the industry’s most common types of equipment and why they’re important for the job. Probably one of the most common pieces of mining equipment, drills are an important part of the underground mining operation. Underground mining is carried out when rocks or minerals are located at a fair distance beneath the ground. But then they need to be brought to the surface. Underground specialized mining equipment such as trucks, loaders, diggers etc. are used to excavate the material and are normally hauled to the surface with skips or lifts for further processing. Drilling is normally required to place explosive charges to liberate the minerals from the overburden material. Underground mining techniques have progressed significantly over the past years, including using remote controlled machinery. Drills assist in creating holes descending underground. If miners are required to work underground, drills can also be used in ensuring the holes are large enough to serve as a portal for miners to enter. Directional drilling is also a type of mining technology where miners will use the tools and certain methods to drill wells. As shown in the adjacent image, a ball mill is a type grinding machine that uses balls to grind and remove material. It consists of a hollow compartment that rotates along a horizontal or vertical axis. It’s called a “ball mill” because it’s literally filled with balls. Materials are added to the ball mill, at which point the balls knock around inside the mill. Ball Mills work by using balls to grind materials. Materials such as iron ore, pain and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates — either on its vertical or horizontal axis. As the ball bill rotates, the balls bounce around while striking the enclosed material. The force of these strikes helps to grind the material into a finer, less-coarse medium. For a ball mill to work, critical speed must be achieved. Critical speed refers to the speed at which the enclosed balls begin to rotate along the inner walls of the ball mill. If a ball mill fails to reach critical speed, the balls will remain stationary at the bottom where they have little or no impact on the material. No industry puts its Pumps through the ringer quite like mining. When the price of commodities such as gold spike in the short term, there is no time to lose--companies have to act fast to extract whatever they can as quickly as possible. While this flurry of activity is great for stockholders, it is not ideal for equipment. Many pumps end up falling prey to a myriad of problems that range from corrosion to being crushed by heavier machinery. To protect mine dewatering pumps to the fullest extent, consider these six common threats that pumps may encounter during mining operations. In the mining industry, Hydrocyclones are mineral processing equipment used in slurry pulps to separate coarse and fine particles according to their size and density. The mixture is injected into the hydrocyclone in such a way as to create the vortex and, depending upon the relative densities of the two phases, the centrifugal acceleration will cause the dispersed phase to move away from or towards the central core of the vortex. Coarse particles exit the bottom of the device (underflow) while fine particles are carried by the central air column and exit at the top (overflow). In metal processing applications, the product stream is the overflow (fine particles) and is typically sent to flotation circuits. The product stream is the underflow (coarse particles), as fines are separated from the final product as a means of quality control. While under certain conditions roping and plugging can occur where the hydrocyclones ceases to classify the particles, the shapes of the discharge are visibly different than normal operating conditions. The roping condition occurs when the amount of solids in the underflow increases to such a point that its discharge velocity is limited, resulting in the accumulation of coarse solids in the separation chamber. This mass passes through the vortex, causing the inner air core to collapse and the discharge at the apex to take the form of a solid stream (rope) consisting of coarse material with high solids density. Roping conditions reduce recovery rates and efficiency in metals processing and lead to quality losses in copper processing. Industrial Conveyor and Parts have many different designs and uses. Common types are belt, roller, motorized roller and overhead conveyors. We categorize them as floor style (mounted on the floor) or overhead. Use them to move products, create buffers and deliver products in sequence for a production line. Manufacturing engineers include conveyors in their production facilities for many reasons: Moving products from point A to B (to avoid wasted time walking, or to reduce movements of forklifts, etc) To carry products that are too heavy to for team members to lift To move a product while operators are working on it (or adding to it). Like a final assembly conveyor at an auto plant To avoid injury to workers from repetitive movement. Or to prevent damage to products caused by movement To deliver products to a robot for processing. Or to receive products from a robot that are ready for the next step Polyurethane & rubber Tensioned Screen Mats provide high wear and corrosive resistant screen media for all applications, from scalping to dewatering. Tensioned Screen Mats are available in a wide range of apertures and shore hardnesses. Tensioned Screen Mats provide superior screening efficiency over conventional screening media, with substantially lower noise levels compared to standard woven wire screens. The abrasion & impact resistance that Tensioned Screen Mats offer increases the product life span compared to woven wire screens.
