Abstract

The invention discloses a processing technology of glass fiber. Specifically, the steps are as follows: adding raw material glass, a clarifying agent, a halide, mirabilite, quartz sand and firefly powder into a melting furnace; heating the melting furnace to make a temperature of the glass rise, first performing preheating, then performing melting, performing wire-drawing on a molten glass liquidby using a wire drawing machine, performing cooling forming on the drawn glass fiber by water, putting the cooled glass fiber into an acid solution, and stirring the acid solution by using an acid resistant pump under assistance of bubbling stirring to enhance ion exchange. The technology is simple and practicable, the produced glass fiber has good insulation, good corrosion resistance, high mechanical strength, and excellent high-temperature resistance, can be used at 1100 DEG C or less for a long time, has good ablation performance, and better high-temperature resistance, chemical corrosionresistance and elastic modulus, and is widely used in manufacturing of precision instrument thermal protection parts, ablation materials, thermal insulation materials and other fields.

Description

Technical field [0001] The invention relates to a glass fiber manufacturing process, in particular to a glass fiber processing technology. Background technique [0002] Glass fiber checkered cloth is a non-twisted roving plain weave fabric, which is an important substrate for hand-laid glass fiber reinforced plastic. The strength of gingham cloth is mainly in the warp and weft direction of the fabric. For occasions that require high warp or weft strength, it can also be woven into unidirectional cloth. It can arrange more twistless rovings in the warp or weft direction. Warp cloth, single weft cloth. Roving is made up of parallel strands or parallel monofilaments. According to the glass composition, the twistless roving can be divided into: E-GLASS alkali-free glass non-twisted roving and C-GLASS medium alkali glass non-twisted roving. Glass fiber is an inorganic non-metallic material with excellent performance. There are many types and the advantage is insulation. Good, stron...
