PRODUCING METHOD OF REVERSE OSMOSIS MEMBRANE BY USING SACCHARIDE

摘要

PURPOSE: A producing method of a reverse osmosis membrane is provided to prevent the decrease of flux when producing a thin film, not to have a bad impact on the characteristic of the thin film while drying and to have a harmless characteristic on a human body. CONSTITUTION: A multi-functional amine solution is sprayed on the surface of a fine porous type, and an excessive solution is removed. Then, a solution contained with an acid halide, a multi-functional sulfone halide or multi-functional isocyanate is sprayed, and a reverse osmosis membrane is produced by after-processing a complex film obtained by interface-polymerization. Accordingly, when producing the reverse osmosis membrane, the safety of a product is secured by not using a harmful material on a human body in an after-process.
