Description

technical field [0001] The invention belongs to the technical field of glass fiber processing, and in particular relates to a processing method for improving the conductivity of glass fiber. Background technique [0002] Glass fiber is an inorganic non-metallic material made of silica. Its main components include silica, alumina, calcium oxide, etc. It is processed into finished products through melting, wire drawing, and weaving. Below a few microns; glass fiber has the characteristics of good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, etc., and is widely used in industrial fields such as composite materials, insulating materials, thermal insulation materials and circuit substrates, but glass fiber The characteristics of brittleness and poor wear resistance, and its excellent insulating properties make glass fibers unable to be used in the application field of conductive materials.
