Efficient filtration equipment for the governance role of the external walls of water pollution phe

Building insulation materials can be divided into inorganic and organic window film. Commonly used inorganic materials exterior insulation rockwool, foams for sale perlite, foams for sale foam cement (concrete), foam glass and glass beads, etc., although there are good fire performance, but the high thermal conductivity, thickness inevitable increased foams for sale building load and increase construction costs. Organic wall insulation polystyrene foam (PS, of EPS, XPS II), polyurethane foam (PU) and phenolic foam (PF), etc., with low density, low thermal conductivity and ease of construction. foams for sale EPS, XPS burning foams for sale class B2 level (flammable), there will be heated above 80 melting softening, shrink drip, smoke billowed from the fire and produce gas. PU flame rating is also the B2 level, although slightly higher softening temperature (110 ), no droplet is like, but drug charges after fire lethal gas produced bigger, people suck a bite or two of gas will immediately fell to the ground and died. Phenolic foam (PF) combustion class B1 level (flame foams for sale retardant), PF flat only 30mm thick 1700 flame subjected to 10 minutes after injection, but not burning surface charring slightly worn, neither fire nor emit smoke and toxic gases. Phenolic foam production of phenolic foam (PF) is a phenol resin as the main material, the blowing agent, surfactant and other additives are mixed, the curing agent was added by a high speed stirring, the mixed slurry was sufficiently within a mold or a continuous casting foams for sale the production line, when the control of a constant temperature, the crosslinked foam, phenolic curing resin made of rigid foam, phenolic foam Short (PF). Phenolic foam fire insulation performance applications in advanced materials in the 1980s, foams for sale foreign scientists through the phenolic resin and its products, and found that they have a prominent fire, smoke, toxic (Fireproof, Smokeless, Toxicityfree, referred FST) characteristics and heat resistance. Made of phenolic foam (PhenolicFoam referred PF) special light density (0.03 ~ 0.08), with excellent energy-saving insulation and soundproofing role, especially PF seizing resistance foams for sale (ablativeresistance), making it the rocket missiles as ablative foams for sale material and flourish. Phenolic foam composite material is a cutting-edge technology of modern stealth fighter requirements, the main material of modern stealth technology stealth, stealth foams for sale coating, plasma stealth, stealth design of structural details and other means. UAVs are mostly structural foam or honeycomb sandwich composite structure, combined with structural details of the design to solve UAV composite stealth technology. Phenolic foam is one of the UAV manufacturing composite materials. U.S. helicopter aircraft carrier, foams for sale its shipboard cabins armor is made of prepreg molding foams for sale technology, a phenolic resin prepreg, because it does not catch fire, it just ablation effectively foams for sale avoid the fire from spreading. The S-2 glass fiber with the ability to absorb high energy. This composite material composition was named "HJ1" composite armor systems. AGY U.S. phenolic composite armor with a new generation of lightweight armor to replace the metal. Inexpensive system S-2 glass fiber reinforced aramid system is replaced. It is an excellent anti-elasticity and FST characteristics suitable foams for sale for small space more armored protection. Phenolic foam was originally a cutting-edge materials foams for sale used in aerospace, aircraft navigation when more than ten thousand meters altitude, low temperature extravehicular to fifty degrees Celsius, while the cabin was warm spring thermal paper, passenger comfort and safety. Since phenolic foam so harsh climatic conditions in the environment safe, why can not be used in the construction sector? Later, it will be gradually pushed foreign, public and civil areas of sports facilities and building housing. The phenolic foam used in the construction of the wall can be considered on a great progress in science and technology. Since the 1990s, including PF, including phenolic composites has been greatly developed, first by the British, the United foams for sale States and other countries military importance, it is used in aerospace, defense industry, and later was used in civil aircraft, ships , railway stations, oil wells and other places stringent fire safety requirements, and gradually to the public and civil fields of sports facilities and building housing.
