Abstract

PURPOSE: To obtain the long life gas filter paper having excellent heat resistance by making a mixture of a ceramic wool of Al2O3, SiO2, etc., and glass fibers into a papery form.
CONSTITUTION: The ceramic wool 1W5μ in diameter is manufactured by melting Al2O3 or SiO2, or a mixture of these at high temperature of approx. 2,000W3,000°C and then blowing the melt out of a nozzle, and then a mixture of 25% the ceramic wool, 70% glass fibers 0.3μ in diameter, and 5% glass fibers 0.2μ in diameter is prepared and then made into a papery form by a paper making machine. The papery substance thus obtained is dried and resinated to obtain the filter paper. Thus, the gas filter paper which is excellent in heat resistance and dust collecting efficiency can be obtained because it contains as much as 25% ceramic wool.
