Glass fiber is an inorganic non-metallic material with excellent performance and is a commonly used reinforcing material for plastics. It is made of pyrophyllite, kaolin, limestone, quartz sand and other mineral raw materials according to a certain ratio and mixed by high-temperature melting and other processes.   Glass fiber is widely used in composite reinforced substrates, electrical insulation materials, heat-resistant insulation materials, light guide materials, corrosion resistant materials and filter materials.   Glass fiber is used in the front body of high-speed rail, which is lightweight, high strength and corrosion resistance   Glass fiber industry chain   Glass fiber production method   Glass fiber is usually produced by the pool kiln wire drawing method: pyrolite and other raw materials are melted into a glass solution in the kiln, and after e...
