Abstract

본 발명은 폴리설폰중공섬유막 및 그 제조방법에 관한 것으로, 막 내부구조의 외측 및 내측사이에는 공동을 갖는 망상구조를 가지며, 미세기공을 갖고, 막 외표면에는지름0.5내지2μ의 기공을 막 내표면에는 0.5내지2μ의 스릿트형 이룬 폴리설폰중공섬유막이며, 폴리설폰수지와 수용성 고분자로 된 방사원액을 2중관형노즐로 방사할때 내부응고액의 응고가를 22내지 30으로 하고, 방사높이를 35내지 80cm로 하여 방사하는 제조방법으로, 내표면의 스릿트형 기공 및 막내부의 공동에 의해 고투수성을 가지며, 막내부의 망상구조로 인해 막의 기계적성질 특히 강.신도가 우수하다The present invention relates to a polysulfone hollow fiber membrane and a method of manufacturing the same, having a network structure having a cavity between the outside and inside of the membrane inner structure, having micropores, and having a pore having a diameter of 0.5 to 2 mu on the outer surface of the membrane. On the surface, it is 0.5 ~ 2μ split polysulfone hollow fiber membrane, and when the spinning solution made of polysulfone resin and water-soluble polymer is spun with double tube nozzle, the coagulation value of the internal coagulation solution is 22 to 30. It is a manufacturing method for spinning from 35 to 80cm. It has high permeability due to the split-type pores on the inner surface and the cavity inside the membrane, and has excellent mechanical properties, especially strength and elongation, due to the network structure inside the membrane.
