HIGH CHEMICAL RESISTANT RO MEMBRANE AND METHOD OF PREPARING THE SAME

摘要

PURPOSE: An additive is not used in other words without after treatment in the amine solution. The chlorine resistance is improved polyamide hollow fiber reverse osmosis membrane is manufactured. The manufacturing method of the hollow fiber reverse osmosis membrane with a superior chemical resistance is offered. CONSTITUTION: The manufacturing method of the hollow fiber reverse osmosis membrane with a superior chemical resistance. The step of the radiation hollows fiber. The polysulfone solution is spread in the hollow fiber emitting. It performs phase transition while passing through cistern. The step manufacturing the porous fiber(30).
