Fiberglass material is an inorganic non-metallic material with excellent performance

Fiberglass is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other national economy fields.
Fiberglass is made of pyrophyllite, quartz sand, limestone, dolomite, boronite, and boronite as raw materials through high-temperature melting, wire drawing, winding, and weaving. The diameter of the single filament is A few microns to more than 20 microns, which is equivalent to 1/20-1/5 of a hair, and each bundle of fiber filaments is composed of hundreds or even thousands of single filaments. According to the shape and length of glass fiber, it can be divided into continuous fiber, fixed length fiber and glass wool; according to the glass composition, it can be divided into alkali-free, chemical resistance, high alkali, medium alkali, high strength, high elastic modulus and alkali resistance ( Alkali-resistant) glass fiber, etc.
