Glass fiber reinforced plastic (FRP) is a new type of composite material. What is the raw material?
Glass fiber reinforced plastics have the advantage of high strength:Ordinary glass is a brittle material of low strength. If fused glass is made into very fine glass fiber, its properties change greatly. Glass fibers are soft and can even be woven into cloth. At the same time, the thinner the glass fiber, the higher its strength. The strength of GRP can be compared to that of reinforced concrete. In reinforced concrete, the main force to bear external force is steel, but concrete is indispensable, it will bond the steel as a whole, not only gives the building components in a definite shape, but also increase the strength. In glass fiber reinforced plastics, glass acts as reinforcing steel, while bakelite acts as concrete. The combination of the two makes glass fiber steel an amazing strength.Glass fiber reinforced plastics not only has high strength, but also has excellent corrosion resistance, thus becoming an important corrosion-resistant material. Lead, once a corrosion resistant metal material, is resistant to sulfuric acid, which is highly corrosive. The reason is that the formation of Pb and concentrated sulfuric acid to dissolve lead sulfate, become a kind of protective film on the surface of the dense metallic lead, so the chemical reaction kettle and lead lined pipes used, can also be used for enamel liner. If fiberglass is used, the corrosion resistance meets the requirements. Also used for glass steel valves, pumps, fans, suitable for the transport of corrosive liquid tank car and train tanker, waste acid waste liquid pool in the village and a large area in the storage tank, chemical plant production storage corrosive liquid corrosion on the ground. The corrosion of petroleum is also very strong, and glass fiber reinforced plastics can be used instead of steel pipes to make oil pipelines and oil trucks, which greatly saves the steel.
The first type of glass fiber reinforced plastics is a composite of glass fiber and phenolic resin. It is a glass fiber impregnated with phenolic resin liquid raw material, after molding, pre molding, and then the phenolic resin curing, made of glass fiber reinforced plastic. Corrosion resistance and long service life. Glass fiber reinforced plastic is a kind of high-quality composite material. It has a special anti-corrosion function for acid, alkali, salt, oil and other corrosive media, and will not rust. The average PVC life is 15 years, while the glass steel life is 50 years.
Building materials market will be on sale. Glass fiber reinforced plastic (FRP) is a kind of composite material made of glass fiber and one or several thermosetting or thermoplastic resins, such as phenolic resin, epoxy resin, polyester resin, polyimide resin, etc.. Glass fiber reinforced plastic is a new type of composite material developed in early twentieth Century. It has many advantages, such as light weight, high strength, anticorrosion, heat preservation, insulation, sound insulation and so on. The first composite was fiberglass, in fact, it had nothing to do with steel. There is no iron in glass fiber, nor is it a composite of glass and steel.
