POLYAMIDE MEMBRANES

摘要

A method for preparing an alcohol insoluble polyamide membrane. An appropriate membrane-forming casting liquid containing the required polyamide is evaporated under conditions of high total humidity and an air flow of less than 305 m/min. (1000 ft/min) in order to form the membrane. Membranes of a single polyamide, e.g. Nylon 6,6 can be formed by the method.
