PROTEK™ brand surface protection tapes and films shield surfaces from dirt, scratches, tool marks, and more. Our easy-peel surface protection tapes and masking films also guard delicate finishes, like metal and glass, from UV rays, stucco, and other surface contaminants. Use our line of temporary protection films during construction, demolition, installations, handling and transport.

LAMATEK Surface Protection Films are easy to apply and remove cleanly when your project is finished. Just unroll the film and smooth it over the surface you want to protect. Make sure your substrate (the surface you’re sticking it to) is clean, dry, and free from any dirt, oil, or debris before you apply the film. Dirty or dusty surfaces will not allow the adhesive to bond properly and then the tape may not stick.
LAMATEK’s masking films are cut into rolls on a 3” core tube. We’ll even custom cut it to your specific custom width.

Finding Your Match
Each PROTEK™ surface protection product is compatible with a specific set of materials and finishes so we do recommend that you test the film in your application. This is especially important with unknown or uncommon substrates.

Expanding Tubes In Heat Exchangers

Before you can start rolling, you will need to select the right expander for the job. Tube OD, and Wall/BWG will determine the size of the expander. However, there are some other factors to consider, such as tube projection, roll length, reach requirements, space constraints, and whether it’s minimum or average wall tubing.Get more news about Condenser Expansion Machine,you can vist our website!

Tube Projection
It’s important to consider if the tube is going to be expanded flush to the tube sheet or if it will have a projection. The most common tube projection for shell and tube heat exchangers is 1/8” from the tube sheet. In situations where all tubes will be rolled to the same projection, an expander with a recess collar should be used. This will accommodate the projection and prevent the tube from being pulled into the expander. The outlet side of surface steam condensers can have varying projections, up to 1X’s the tube diameter in length. In this case a telescoping or full recess collar should be used. If no tube projection is specified, the tube expander will come with a flush collar to expand the tube flush to the tube sheet.

Roll Length
Tube expanders come in two different roll lengths: short and long roll. In order to determine the correct roll length, you will need to know the tube sheet thickness. Choose the roll length that will expand the tube sheet area in the least amount of expansions. If expanding tubes in a double tube sheet, the inner primary tube sheet thickness must be specified so the expander’s rolls can be manufactured to allow for the proper effective expansion length. Whereas, the outer tube sheet would use standard rolls.
Reach Requirements
Generally, tube expanders come in 4”, 8”, 12”, and 18” reaches, but can be made longer to accommodate specific applications. For optimum tool life, use the shortest reach expander that will accommodate the application. Long reach expanders are used in heat exchangers with thick tube sheets or when reaching through water boxes, found in air coolers.

Space Constraints
Heat exchangers with channel boxes or division plates where the tubes are positioned too close to a wall for the expander’s collar to access perimeter tubes will require a friction collar. This collar is smaller in diameter than a standard collar, allowing more access to difficult areas. A friction collar should only be used as needed, as it’s not a replacement for a bearing collar.

Average Wall v Minimum Wall
When ordering tubes, it is very unlikely that each tube wall thickness will be exactly the same. Industry tolerances allow for ±10% thickness. That’s a total variation of up to 20% from the smallest to largest thickness, resulting in a wide range of sizes. For example, if you have .083” average wall tubes, the actual wall could be anywhere between .091” and .075”. If you were to buy a 14 BWG expander to fit .083, it would likely still work for either extreme due to the expansion range that the tool is capable of achieving.
A min wall tube offers the same total variation in wall thickness that an average wall tube does, but the variation is applied differently. It allows for -0% and +20%. So the wall will never be less than the specified thickness. For example, a .083” min wall tube will range from .083” to .100” wall thickness.

At the upper end of that range, a normally sized tube expander will not have enough clearance to enter the tube. If you have min wall tubing, it is recommended that you drop down one expander size. So instead of ordering a 14 BWG expander, you would drop down to a 13 BWG. This ensures that the expander will fit inside of the tubes and still achieve the proper range of expansion.

Setting Up A Condenser Expander
Once the right tool has been selected, the tube expander’s collar will need to be set to the correct roll depth. Generally, you want to set the rolls 1/16” to 1/8” from the back of the tube sheet. This will ensure that the tool does not roll beyond the tube sheet. Simply, loosen the set screw on the collar, adjust the collar threads to the desired roll depth, and tighten the set screw on the expander’s cage flat. This will allow the expander to be adjusted to other depths if necessary.

Choosing the Right Vinyl

How to compare cast vs calendered film in terms that are clear enough to make good purchasing decisions but not so Technical that you would fall asleep before figuring it out? Still awake? I swear no more mention of the “T” word.Get more news about vinyl film,you can vist our website!

Think of it this way; time in the sun is never your friend when you happen to be a material that was chosen for cost rather than durability. Think of those tourist shop umbrellas that are sun-bleached after one season and end up splitting at the seams by season two.

This is the same thing – the sun shade and vinyl are meant to handle many common or short-term applications but they get wrongly used. Then, they are accused of being cheap when they fade, fail or fall apart. When it comes to tougher applications over a longer warranty it pays to buy the right materials in the first place then have to replace them later. As anyone who has had the pleasure of “redoing” vinyl graphics knows the lowest cost involved is the vinyl itself. Removal of cracked or brittle film and the very bad rap that lands directly on the sign shop are far more expensive than your vinyl investment.

There are far too many specific details having to do with vinyl and the makeup of vinyl I can cover but I’ll stick with the primary decision points.The very names given to these two types of vinyl film (cast or calendered) can tell us a lot about their best application. Cast film is produced by first turning the ingredients of the finished film; PVC resin, plasticizer, colorant, etc. into paint by the use of a solvent. When matte, semi-gloss or high gloss vinyl is required then the mold film will be a mirror of that texture. The thin wet colored, clear or white vinyl film is then dried and cured at a rather high temperature to form a very flexible film. There are many connections between the ingredients that are bonded via process temperatures far higher than any application will experience. Now we can see why cast film can take so much distortion, heat abuse (such as that in thermoforming a sign face) and sun energy without losing its flexibility and cracking, fading or popping away from curves or tight corners such that are encountered in vehicle wraps.
Calendered film is not made through the paint casting method but instead through a “melt” process which involves the same type of ingredients as cast film. Instead of being carried through a coating unit onto a mold and then drying into a thin film of about 2 mils (50 microns), calendering first melts the ingredients at about half the temperature used to fuse cast film ingredients. As it cools the molten PVC is rolled through “calendering” rollers to achieve the final width, thickness and surface finish before being wound up for further processing.

This results in a film that doesn’t quite have a resistance to the wide range of sign making processes (such as thermoforming), applications (such as south facing dark sign faces) or environments (from Sao Paulo, Brazil to Saint Paul Minnesota). Long-term signage and its associated colors will need to stand up to all of these elements without fading, cracking or peeling away.

So the next time you see some junior member of a competitive sign shop removing a prematurely crippled sign or wrap and reinstalling what can only be a “redo”; most likely you will see that little thought bubble above his head saying, “How did this happen?”, well, you’ll know the answer!

The Best Silicone Sealant to Buy Now According to 30,000+ Reviews

Silicone sealants are used in a variety of professional and household applications. Compared to acrylic sealants, and other adhesives and caulks, silicone is a flexible material that retains its stability in both high and low temperatures. It is resistant to water, moisture, and many chemicals, and provides a long-lasting gap seal. These characteristics make silicone sealants perfect for building and repairing projects in kitchens, bathrooms, doors, windows, and other applications.Get more news about Weatherproof Silicone Sealant,you can vist our website!

There are various types of silicone sealants designed for different applications. Multi-purpose silicone sealants, such as the Gorilla silicone sealant, are great sealers to have at home for easy repair projects around the house. Sanitary silicone sealants, such as the GE GE5070, are typically applied in bathrooms and kitchens, as they contain fungicides to prevent mold and mildew formation. Frame silicone sealants, like the GE GE012A, are durable and weatherproof products ideal for use on window and door frames. High-temperature silicone, such as the J-B Weld 31314, is formulated to withstand the extreme temperatures that can be reached in electrical or industrial applications. Aside from protecting against water moisture and weather elements, silicone sealants also offer great protection from various harmful elements. For more on how silicone sealers can protect industrial equipment from contaminant damage, read here.

For smaller projects and touch-ups, some silicone sealants like Loctite's version are available in squeezable tubes with precision tips for easy application. For bigger, more complex projects, silicone sealers are available in cartridges that can be used with caulking guns. Unlike acrylic sealants, silicone sealants typically cannot be painted over, but they are available in different colors to match the surface on which it is to be applied.

This Gorilla sealant is made of pure silicone and is excellent for any heavy-duty or touch-up project. The sealant is waterproof and can be used in both indoor and outdoor applications. It is mold-, and mildew-resistant and dries in as fast as 30 minutes. This multi-purpose sealant can be used around the house for waterproofing shower or bathtub joints, gaps in windows, gutters, downpipes, or for sealing gaps around sinks and countertops. One of the many happy customers wrote, “This is going to be my go-to for bathroom/kitchen sealing because it really did repel water after just a few hours. A follow-up check confirmed that it held up well after a week and didn't get washed away like other caulks before.”

For small applications and quick repairs, the Loctite silicone sealant comes in a handy compact tube that is easy to store in a small cupboard until the next time you need to use it. This multipurpose sealant is compatible with porcelain, fiberglass, ceramic, metal, and many other materials typically used in bathrooms, kitchens and windows, and door frames. The silicone is clear and matches any color and finish. One of the reviewers wrote, “Great product and fair price. Used to caulk up the corners of my shower frame and tub. Initially had an issue with water escaping through the cracks and onto the bathroom floor. After using this, [I] have no issues with leakage, and [it] seals nicely.”

With 10-year mold-free product protection, the GE5070 is one of the best silicone sealants for tubs, showers, backsplashes, sinks, countertops, and other areas exposed to water. This silicone is designed to protect against mold and mildew growth while providing a durable seal. It is safe to use on many high-end metal finishes without causing discoloration and has a neutral-cure formula that emits low odor while curing. A happy customer explained, “I bought this to seal around my bathroom toilet and tub during the remodel. It sticks very well and you have to scrape it off if you ever need to remove it. When it dries, this sealant creates a rubber seal that will not leak.”

The DAP silicone sealant works equally well in indoor and outdoor applications. It is compatible with fiberglass, ceramic, rubber, porcelain, and other materials, and it forms a strong, mildew-resistant seal that lasts and does not crack. Thanks to its strong, professional-grade formula, this silicone sealant is one of the best sealants for use outdoors in areas exposed to rain, humidity, and both hot and cold temperatures. One of the reviewers wrote, “Working great so far on the kitchen tile, sealing a couple drywall cracks near the fireplace and outside on some openings around the house. It's dried very consistently with no movement in some much larger gaps.”

What Is Sintered Stone?

When it comes to countertops, the first thought is usually quartz or granite. However, there's a new material, Sintered stone. Popular in Europe, already taking over 70% of the market. Sintered stone is like porcelain, but is subjected to much higher pressure and heat during manufacturing, resulting in a metamorphic process to bind natural materials with out resins or binders.Get more news about Sintered Stone,you can vist our website!

By taking natural minerals and processing them with this method, the end result has outstanding physical properties such as resistance, durability and compactness. While great for countertops, Sintered stone can be used for virtually any surface, from patios to fireplaces, this material is the modern solution.

Ok, so we’ve discussed and demonstrated that the Airwatts published in a product brochure are not a good measurement of performance. Instead, the quality and longevity of a motor should be weighed in your cost evaluation along with any performance claims.

Imagine that a central vacuum motor is much like a jet engine. Turbine propellers are spinning at thousands of RPM’s (revolutions per minute) generating a tremendous amount of Vacuum and producing a huge amount of Airflow. A central vacuum motor operates along the same principle.


While the Airflow measurement indicates how much air the central vacuum motor can move, the Suction measurement tells us the maximum pull the motor is capable of. This is determined by sucking a 2 inch column of water vertically to its maximum height in inches. Hence, the term “Waterlift”.

The performance curve of a central vacuum motor has an “inverse relationship” meaning that when Airflow is at its maximum, Suction is at its weakest - and vice versa.
The term Airwatts was created to determine the ‘sweet spot’ at which Suction and Airflow co-exist at their most efficient orifice along the performance curve. However, like any brochure performance claim, the maximum value falls outside the typical operating orifice of a working central vacuum system.

The same is true for both Suction and Airflow. A central vacuum does not operate at a 2 inch orifice where Airflow is at its greatest. Nor would you be able to vacuum anything at a 0 inch sealed vacuum orifice when suction is greatest.

Like autumn leaves blowing across an empty parking lot, it’s the movement of air (Airflow) which carries dirt away in your central vacuum system. Just like in nature, it’s the difference in atmospheric pressure (Vacuum) that creates both the movement and velocity of air.


The amount and speed at which air travels (velocity) has a direct impact on your central vacuum’s ability to move debris. In the case of a gentle ocean breeze versus a tornado or a hurricane, this is the difference between drying your laundry and ripping your house off its foundation.

Aluminum Die Casting for Automotive Industry

Automotive industry is at the forefront of this trend looking for effective alternatives to cut down on weight without sacrificing durability, which is under constant pressure to adhere to increasingly strict fuel economy standards. With CAFE standards becoming increasingly stringent, automobile manufacturers have been forced to continually find new ways to increase fuel economy. It has been the primary strategy that manufactures lighter vehicles to improve gas mileage, and the use of aluminum parts that replace steel parts has been the most popular method to reduce vehicle weight. Over time, aluminum has been progressively incorporated into automotive doors, trunks, hoods, and engines. Today, aluminum makes up a much more significant percentage of the vehicle. According to Ducker Worldwide, aluminum is now the leading material used in the manufacturing of engines and wheels in automobiles. Audi has been manufacturing an all-aluminum structure for its A8 model for nearly 20 years, and other companies in the industry are beginning to follow suit. Currently, Ford is developing an all-aluminum structure for its F-150 pickup, the best-selling vehicle in North America.Get more news about Aluminum Die Casting Auto Parts,you can vist our website!

Heavy usage of aluminum in automobiles first began with Audi’s 1994 A8 model.3 Since then, standard consumer automobile manufacturers have been amplifying the aluminum used in their vehicles and are beginning to transition to primarily aluminum-based vehicle bodies. Ford has become one of the pioneers in aluminum usage for the automobile body, aiming to release an aluminum-body F-150 in 2015. Changing the body from steel to aluminum is expected to cut the weight of the car by about 700 pounds, or 15 percent of current vehicle weight, which would increase fuel economy by as much as 25 percent. The decreased weight in the vehicle also improves towing, hauling, acceleration, and stopping abilities making it an all-around more efficient vehicle than its steel-based counterpart. Because the F-150 is the undisputed leader in American pickup truck sales as well as the best-selling automobile in North America, other large automobile manufacturing companies are likely to follow suit and incorporate greater amounts of aluminum parts into the body of their vehicles. A shift from steel to aluminum in the body of vehicles by more than just Ford could help the demand for aluminum increase by as much as 40 percent in the upcoming years.
The trend of using aluminum to reduce a vehicle’s weight is expected to continue throughout the industry. Aluminum is lighter, more energy efficient to process, and has comparable pound-for-pound to steel. Steel’s heavy nature has become a burden on fuel efficiency. While aluminum has been identified as the most effective material for light weighting, its use often involves a tradeoff of strength for weight when compared to steel. Structural durability of aluminum components is often considered their biggest drawback; however, even that is less of a concern as aluminum can be made nearly as structurally strong as steel through processes such as heat-treating. A majority of the aluminum used in the body of vehicles is 6000-series alloy aluminum, which is heat-treated to the end user’s desired strength. The strength of heat treated aluminum alloy is capable of exceeding that of some grades of steel while still retaining its light weight and malleability. Power tools that cannot be used with steel can cut through or hammer down aluminum leading to both cost and speed advantages in the production cycle. Aluminum can also be designed to absorb as much as two times the crash energy compared to mild steel.

Aluminum, when replacing steel in today’s vehicles, could save approximately 44 million tons of CO2 emissions per year, and nearly 90 percent of the aluminum used in vehicles is recycled at the end of its lifecycle. The automotive industry is expected to continue to grow in the U.S., and aluminum is expected to play an increasingly important role in this attractive market. Results from an Alcoa study have shown that for every ten percent reduction in vehicle weight, fuel economy can improve between five and seven percent.7 Additionally, as many as 83 percent of car buyers are willing to spend more for a fuel efficient vehicle,8 further motivating automotive manufacturers to focus more efforts on light weighting.

Automotive casting has been increasing at a CAGR of approximately five percent over the past few years and is expected to grow more rapidly over the next decade as environmental trends and government regulations on fuel efficiency continue to tighten.

During the process of die casting, molten metal is injected into two parts of a shape (the die), which are stuck together. The metal is injected under high pressure. After it has cooled, the two parts of the die come loose and the part is removed. Because the same die is used again and again, each part comes out looking exactly the same. The process of designing the die is the only technically difficult part of the operation. A lot of factors have to be considered to make sure that no air gets trapped inside the molten metal when it is injected and calculations on the draft angle have to be made to make it possible for the part to be ejected easily. This process is used in almost every industry in the world and it is unlikely that you are not surrounded by items right now that have been created through a die casting process.

How Important is Dental Crown Material Choice?

Has your dentist recommended you have a dental crown placed? Do you know that entails?Get more news about Fashion Dental,you can vist our website!

There are different materials used to fashion dental crowns. Unless you have received a dental crown in the past, you have probably not given much thought to the material used to make one. If you have not received extensive dental work, it might not even be clear when someone might need to get a dental crown.
A crown is a prosthetic tooth that fits over your existing tooth. They consist of a variety of materials, and the choice is an important factor in how the crown functions. When tooth decay becomes more serious, a dental crown may become necessary. Many dentists, after performing a root canal to remove infected dental pulp, place a dental crown on the tooth to protect it from further damage. Dental crowns can also be used aesthetically to restore a broken or chipped tooth.

There are many different types of materials used to make dental crowns. Each type of crown has its advantages and drawbacks. There are a couple of things to consider when choosing a crown material. One can be if you have any allergies to metal and you may choose a non-metallic crown. Another consideration is how close the soon-to-be treated tooth is to the front of your mouth. It would make more sense to get a crown made of less visible material.

Gold is a common material for crowns. Gold alloy has been used for years in dental implants, and it is one of the strongest choices. Another advantage is that gold is relatively inert around biological tissue, meaning that it is easy on the cells of your mouth. It does not cause any allergic reactions or inflammation. Gold alloy is strong enough to resist teeth grinding and can be a good choice if you experience this condition.

Another option is porcelain. Porcelain is the best cosmetic option as it looks and feels the most like natural tooth enamel. It is also less sensitive to changes in temperature, so it will not feel too hot cold like its gold counterpart. There is a major downside, however, as porcelain fractures very easily, requiring a new crown if it breaks.

There are a few solutions to the issue of frailty in porcelain crowns. Porcelain can be combined with metal to create a crown that is porcelain fused to metal, or PFM, crown. Moreover, it can be mixed with Zirconia. Both of these options fix the issue of porcelain fragility while maintaining the great natural look of this material. For those with a metal allergy or sensitivity, porcelain with zirconia will be the option of choice.Ultimately, the choice of your dental crown material will be a mutual decision between you and your dentist. Be sure to ask your dentist which material is best for your specific situation. It is important to be as informed as you can be before making the decision.
