PROCEDIMENTO PER LA PRODUZIONE DI PRECURSORE DI FIBBRA DI ALLUMINA E RELATIVA APPARECCHIATURA

摘要

Disclosed herein is a process for the production of the precursor of alumina fiber. The process comprises causing a thick solution for alumina fiber having a viscosity in the range of from 500 to 2000 cps to be continuously fed through the feed pipe protruding into the opening at the center of a funnel-shaped disk and to be sent flying with hot compressed air and thereby converting the thick solution into fibers.
