The glass fiber

Fibreglass (Fibreglass) is a kind of inorganic non-metallic material with excellent performance, and there are many kinds. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittle and poor wear resistance. It is the pyrophyllite, quartz sand, limestone, dolomite, boron calcium stone, six kinds of szaibelyite ore as raw material by high temperature melting system, wire drawing, winding, weaving and other manufacturing processes, the monofilament diameter of a few microns to over 20 microns, the equivalent of a human hair 1/20-1/5, each bundle fiber original SiDou consists of hundreds or even thousands of root monofilament. Glass fiber is usually used as reinforcement material in composite materials, electrical insulation materials and thermal insulation materials, electric roadbed board and other fields of the national economy.
