Production process of quartz fiber products
Quartz fibers are a kind of special glass fiber with SiO2 purity more than 99.9% and filament diameter 1-15μm. They are high temperature resistant and could be used at 1050 ℃ for a long time, be used as high-temperature ablation protection material at 1200 ℃ for a short time, without shinkage at high temperature.
Quartz fibers are made of pure natural crystal, which are refined and processed into fused quartz glass rod. The purity of SiO2 > 99.9%. In the drawing process, the heating methods including hydrogen oxygen flame method and plasma method, different sizing agents are also used according to applications of quartz fibers.Quartz fiber products including quartz fiber untwisted yarn, quartz fiber twisted yarn, quartz fiber cloth, quartz sleeve, quartz chopped strand, quartz wool, quartz felt, etc
