GLASS FOR PRODUCING CONTINUOUS GLASS FIBRE

摘要

FIELD: chemistry.SUBSTANCE: glass for producing continuous glass fibre contains components in the following ratios, wt %: SiO50.0-60.0; AlO10.0-20.0; CaO 12.0-16.0; MgO 6.0-10.0; TiO4.0-10.0; RO (NaO+KO) 0.1-0.7; ZrO0.01-0.4; FeO0.01-0.5, wherein the glass has a low upper limit crystallisation temperature of 1240°C and first hydrolytic class chemical resistance.EFFECT: high useful time coefficient of the process of forming fibre and low drop breakage, high efficiency of the glass-melting vessel.1 tbl
