Title (EN) REVERSE OSMOSIS MEMBRANE AND PRODUCTION METHOD THEREFOR
(FR) MEMBRANE D'OSMOSE INVERSE ET SON PROCÉDÉ DE FABRICATION
(KO) 역삼투막 및 이의 제조방법
Abstract: front page image
(EN)The present invention relates to a reverse osmosis membrane using a polyolefin-based microporous membrane and a production method therefor. The present invention relates to a method for forming a polyamide layer by interfacial polymerization on a polyolefin-based microporous membrane without separate hydrophilization treatment, wherein reaction solutions are fed in a specified order upon the interfacial polymerization to effectively form the polyamide layer on a polyolefin-based microporous membrane having hydrophobicity.
(FR)La présente invention concerne une membrane d'osmose inverse utilisant une membrane microporeuse à base de polyoléfine et son procédé de production. La présente invention concerne un procédé de formation d'une couche de polyamide par polymérisation interfaciale sur une membrane microporeuse à base de polyoléfine sans traitement d'hydrophilisation séparé. Les solutions de réaction sont introduites dans un ordre spécifié lors de la polymérisation interfaciale pour former efficacement la couche de polyamide sur une membrane microporeuse à base de polyoléfine ayant une hydrophobicité.
(KO)본 발명은 폴리올레핀계 미세다공막을 이용한 역삼투막 및 이의 제조방법에 관한 발명이다. 본 발명은 폴리올레핀계 미세다공막을 별도의 친수화 처리 없이 계면중합에 의해 폴리아미드층을 형성하며, 계면중합 시 반응용액의 투입순서를 특정함으로써 소수성을 갖는 폴리올레핀계 미세다공막에 폴리아미드층을 효율적으로 형성시키는 방법에 관한 것이다.
