Benefits and importance of using Polyurea Grease








This video demonstrates how polyurea can be used to line the steel tank as rusted completely through the owner said this truck leaked so badly. It could not be used on public roads. This tank was about ten years old and, as you can see, it had severe rust. In fact, there's several areas that had scale rust on had to be mechanically removed from the tank before we could actually sandblast it. Here a hammer is being used to remove the scale Russian, the tank, removing it makes sandblasting much more efficient here the tank is being sandblasted, the sandblasting is complete and the metal has been primed in preparation for the lining system. You can see several holes, they have rusted completely through the tank. These holes are repaired using polyurea, geotextile and metal. Here you can see the holes in the top of the tank or is rusted completely through. Here are some shots of the polyurea on the outside of the tank and on the inside. Polyuria has estimated life spans as high as 75 years on a water tank like this, it will most likely outlast the truck. Keep us in mind for any of your lining or coding needs southeastern industrial linings. Give me a call at 40 for 62 64 771. My name is David Puckett and thanks for watching our video

Spray Foam and Polyurea Insulate and Protect Hot Wax Tanks








This week we visit green life, energy solutions, a division of national spray, foam and coatings. The company is nor pack Inc, the location is Newark New Jersey. The job is to refurbish these large steel tanks and insulate them and cover them with a durable, polyurea protective coating. There are eight tanks and all the tanks were originally covered, an old fiberglass insulation that did not hold up to the environment. The tanks are used to store hot liquid wax for processing to various OEM products, such as wax paper. The job starts with an abrasive blast. Cleaning and surface preparation of the dirty steel tanks dry ice was selected as the blast media, based on its ease of cleanup, low residual mess and its high quality performance in cleaning the steel tanks. Once the tanks are blasted to a clean surface, a very thin coat of primer is applied to aid in the adhesion of the spray foam spray foam insulation is perfect for insulating industrial tanks, where liquids are kept hot or cold. The foam insulation can save the plant owners multiples of what the original cost is over the life of the tanks. On a side note, this job came as a referral from a related wax plant where they saw a market decrease in their utility bills after insulating their tanks, with spray foam, the owner of that plant told norpac of their energy saving successes, and this job was specified In order to stand up to the high operational temperatures of the tanks, this particular application specified emelec USA's special high temperature capable spray foam. Once the foam is applied to all the tanks, they are covered with a top coat of poly urea for durability and easy cleanup and maintenance. We thank Ken Ryan and his crew at green life, energy solutions and national spray, foam and coatings Inc for letting us into film. Yet another great application of spray foam and polyurea coatings.

ARE THERE HAZARDS WITH USING POLYUREA COATINGS?

Recently, we were surprised to find that a company that sells blast-resistant structures presented an article concerning the potential risks of polyurea coatings when applied to blast-resistant structures. The material comprised factoids from three seemingly scientific studies, though the reviews were not referenced by name in the article. In short, the article appeared to question the sanctuary of using polyurea coatings on blast-resistant structures. THE HAZARDS OF POLYUREA COATING Our buildings are blast-resistant with or without polyurea. We're proud to say that our buildings have polyurea coatings, but those coatings have no bearing on the blast-resistance of our structures. Moreover, we don't make any claims that polyurea is put on the buildings to affect the blast-resistance. WHAT IS POLYUREA? Polyurea is a highly flexible elastomer. It's commonly used in the consumer world as a lining for truck beds, and has many industrial uses, like as a coating or lining for steel pipes and tanks to protect from corrosion, as a roof coating to give reflectivity and a cooling effect, and as a containment arrangement in marine and aquarium designs, just to name a few. It can be used, as the article declared, to enhance the blast-resistance of masonry surfaces. However, we use it on our blast-resistant modular steel buildings, not for blast-resistance, but because it is a very resilient coating. Our buildings are made to be moved around, and they're placed in areas with the harshest conditions, so it's essential that they can take a beating. The resilient coating also shields the structure from corrosion. WHAT ABOUT THOSE STUDIES ON POLYUREA AND BLAST-RESISTANCE? Our technicians find those studies to be unclear at best, with both positive and adverse findings. The reference tests that were done on steel plates of varying thickness, similar to what you might find on the corrugated walls of a BRB. Moreover, unfortunately, there are no industry figures for blast-resistance. (In our white paper, The Next Step in the Evolution of Blast-Resistant Buildings, we acknowledge the need for industry models.) When it comes to blast-resistance, we're all about structure. The structural integrity of a building's design is the most important factor in blast protection. The wall panels are essential, but our blast test reveals that the fundamental framework is what holds things together in the event of a blast. When the structure itself has redundancies built into the walls and roof, like the close spacing of the wall studs, the outer coating won't have any bearing on structural integrity. However, if the structure has more full spaced studs and relies primarily on the corrugated steel of the walls rather than the skeletal structure of the device, then it is possible that something like polyurea could affect blast-resistance. This shows the significance of selecting a BRB with firmly placed beams in the framework of the design. To sum up, one cannot conclude the polyurea harms the blast performance of all blast-resistant modular structures.
