Method for preparing Polyamide Membranes without Skin, licuofilas and insoluble in alcohol

摘要

Method for producing Polyamide Membranes without Skin, licuofilas and insoluble in alcohol.Is dissolved in a Solvent of polyamide from 0.01 to 5% of a Polyamide Resin insoluble in alcoholWe have a relationship between CH: nhco 7: 1 and 1: 12; induce nucleation controlled by addition of a non Solvent of the Polyamide Resin; extend the solution on a substrate; Film Cooling until the Dissolution temperature of gelation; contacting and thin film A non Solvent Liquid; washing and drying the resulting membrane.These Membranes have Applications including Filtration media to eliminate Fluid particles and Microorganisms in suspension.
