MANUFACTURING METHOD OF ANTIBIOTIC ULTRAFILTRATION

摘要

The utrafiltering membrane is manufactured by (a) making polyprophylene master batch containing nonporous inorganic ceramic with 2-50% metal compound such as silver and zirconium being able to sterilize; (b) making polyprophylene fabric with 0.1-5 wt% nonporous inorganic ceramic; (c) coating fine porous layer with polysulfone, polyestersulfone or polycarbonate. This antibiotic polyprophylene fabric can be used to purify water.
