Title (EN) POLYAMIDE-BASED WATER-TREATMENT SEPARATION MEMBRANE HAVING EXCELLENT SALT REMOVAL RATE AND PERMEATION FLUX CHARACTERISTICS AND METHOD FOR MANUFACTURING SAME
(FR) MEMBRANE DE SÉPARATION À BASE DE POLYAMIDE POUR LE TRAITEMENT DE L'EAU AYANT UN EXCELLENT TAUX D'ÉLIMINATION DE SEL ET D'EXCELLENTES CARACTÉRISTIQUES DE FLUX DE PERMÉATION ET SON PROCÉDÉ DE FABRICATION
(KO) 염제거율 및 투과유량 특성이 우수한 폴리아미드계 수처리 분리막 및 그 제조 방법
Abstract:
(EN) The present invention relates to a method for manufacturing a water-treatment separation membrane having improved salt removal rate and permeation flux characteristics and to a water-treatment separation membrane prepared by the manufacturing method, the method comprising the steps of: forming an aqueous solution layer containing an amine compound on a porous support; bring into contact an organic solution containing an acyl halide compound and a first organic solvent with the aqueous solution layer to form a polyamide active layer; and coating a second organic solvent having lower volatility than the first organic solvent on the polyamide active layer.
(FR) Cette invention concerne un procédé de fabrication d'une membrane de séparation pour le traitement de l'eau ayant un taux d'élimination de sel et des caractéristiques de flux de perméation améliorés et une membrane de séparation pour le traitement de l'eau préparée par ledit procédé de fabrication, le procédé comprenant les étapes suivantes : la formation d'une couche de solution aqueuse contenant un composé d'amine sur un support poreux ; la mise en contact d'une solution organique contenant un composé d'halogénure d'acyle et un premier solvant organique avec la couche de solution aqueuse pour former une couche polyamide active ; et l'application d'un second solvant organique ayant une volatilité plus basse que le premier sur ladite couche polyamide active.
(KO) 본 발명은 다공성 지지체 상에 아민 화합물을 포함하는 수용액층을 형성하는 단계; 상기 수용액층 상에 아실 할라이드 화합물과 제1 유기용매를 포함하는 유기용액을 접촉시켜 폴리아미드 활성층을 형성하는 단계; 및 상기 폴리아미드 활성층 상에 상기 제1 유기용매 보다 휘발성이 작은 제2 유기용매를 도포시키는 단계를 포함하여 염제거율 및 투과유량이 향상된 수처리 분리막의 제조방법 및 상기 제조방법으로 제조된 수처리 분리막에 관한 것이다.
