Description

technical field [0001] The invention belongs to the field of glass fiber processing, and in particular relates to a glass fiber and a processing technology thereof. Background technique [0002] Glass fiber (original name in English: glass fiber or fiberglass) is an inorganic non-metallic material with excellent performance. Brittle, poor wear resistance. It 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 its single filament is several Micron 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. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other national economy fields. [0003] Compared with organic fiber, glass fiber has higher ...
