Title (EN) POLYSULFONE-BASED HOLLOW FIBER FILM HAVING EXCELLENT STRENGTH AND WATER PERMEABILITY, AND METHOD FOR MANUFACTURING SAME
(FR) FILM EN FIBRES CREUSES À BASE DE POLYSULFONE PRÉSENTANT UNE TRÈS GRANDE RÉSISTANCE ET UNE TRÈS BONNE PERMÉABILITÉ À L'EAU, ET SON PROCÉDÉ DE FABRICATION
(KO) 강도 및 수투과도가 우수한 폴리설폰계 중공사막 및 그 제조방법
Abstract: front page image
(EN)The present invention relates to a polysulfone-based hollow fiber film having 20-25 wt% of a polysulfone resin (A), 45-55 wt% of an organic solvent (B), and 30-35 wt% of a hydrophilic additive (C), the hollow fiber film having an asymmetric sponge structure, in which pore sizes increase continuously going from an outer surface layer to an inner surface layer, and the ratio of the pore sizes of the outer surface layer and the inner surface layer is 1:10-1:10000, and a method for manufacturing the polysulfone-based hollow fiber film comprises the steps of: preparing a spinning undiluted solution including a polysulfone-based resin (A), an organic solvent (B), and a hydrophilic additive (C); preparing an inner coagulant; spinning the spinning undiluted solution and the inner coagulant; forming pores; and winding, wherein the step for forming the pores is spun when the total retention time in the coagulation set and washing set exceeds 90 seconds.
(FR)La présente invention concerne un film en fibres creuses à base de polysulfone comportant 20 à 25 % en poids d'une résine de polysulfone (A), 45 à 55 % en poids d'un solvant organique (B) et 30 à 35 % en poids d'un additif hydrophile (C), ledit film en fibres creuses présentant une structure spongieuse asymétrique, dans laquelle la taille des pores augmente sans interruption en allant d'une couche superficielle extérieure vers une couche superficielle intérieure, le rapport entre la taille des pores de la couche superficielle extérieure et celle de la couche superficielle intérieure variant de 1/10 à 1/10 000. L'invention concerne également un procédé de fabrication dudit film en fibres creuses à base de polysulfone comprenant les étapes consistant à préparer une solution non diluée de filage contenant une résine à base de polysulfone (A), un solvant organique (B) et un additif hydrophile (C) ; à préparer un coagulant interne ; à filer la solution non diluée de filage et le coagulant interne ; à former des pores ; et à procéder à un bobinage, l'étape de formation des pores étant achevée lorsque le temps de séjour total dans le bain de coagulation et le bain de lavage dépasse 90 secondes.
(KO)본 발명은 폴리설폰계 수지(A) 20 내지 25 중량%, 유기용매(B) 45 내지 55 중량% 및 친수성 첨가제(C) 30 내지 35 중량%를 포함하는 폴리설폰계 중공사막으로서, 상기 중공사막은 외부 표면층에서 내부 표면층으로 갈수록 연속적으로 기공크기가 증대되는 비대칭 스폰지 구조이고, 외부 표면층과 내부 표면층의 기공크기의 비율이 1:10 내지 1:10000인 것을 특징으로 하는 폴리설폰계 중공사막을 제공하며, 상기 폴리설폴계 중공사막의 제조방법은 폴리설폰계 수지(A), 유기용매(B), 및 친수성 첨가제(C)를 포함하는 방사원액을 준비하는 단계; 내부응고액을 준비하는 단계; 상기 방사원액 및 내부응고액을 방사하는 단계; 기공 형성 단계; 및 권취단계를 포함하고, 상기 기공을 형성하는 단계는 상기 응고조 및 세정조에서 총 체류시간이 90초를 초과하여 방사되는 것을 특징으로 하는 폴리설폰계 중공사막의 제조방법에 관한 것이다.
