PROCEDIMENTO PER LA FILATORA A SECCO DI FIBRE DI VETRO SOLUBILE E PRODOTTO OTTENUTO

摘要

Process for the production of water containing water glass fibers of the type in which alkali water glass is dry spun into water containing fibers, the improvement being dry-spinning water glass free from non-alkaline compounds having a molar ratio of alkaline oxide to silicon dioxide of from about 1:3 to 1:1.9 and a viscosity of about 10-700 Pa measured at 30 DEG C., at 10 DEG -50 DEG C. in a drying funnel of a temperature of more than 100 DEG C., at a discharge velocity of minimum 5m/min.
