Claims (3)

  1. 이중관 구조의 중공사 제조용 노즐을 이용하고, 방사원액인 폴리설폰 수지와 유기용매 및 첨가제로 이루어진 방사용액을 방사하여 응고시킴으로써 중공사 분리막을 제조함에 있어서, 상기 중공사 제조시 방사원액으로서의 폴리설폰계 수지 10∼25중량%와 유기용매 45∼85중량%, 빈용매(poor solvent)첨가제 0∼30중량%, 용출성 고분자 첨가제 0∼20중량%, 무기염 첨가제 0∼8중량% 및 무기산 0∼1중량%로 이루어진 방사용액을 사용하되, 상기 방사용액의 방사시 내부 응고제의 온도는 상기 방사용액의 온도와 30℃이하의 차이를 유지하며 외부 응고제의 온도는 5∼60℃로 조절하여 응고시키고, 이때의 권취속도는 10∼45m/min으로 조절하여서 됨을 특징으로 하는 폴리설폰 중공사 분리막의 제조방법.
  2. 제1항에 있어서, 상기 빈용매 첨가제, 용출성 고분자 첨가제 및 무기염 첨가제의 총사용량은 40중량%이하가 되도록 하고, 이들 3가지 첨가제중 적어도 어느 한성분은 사용함을 특징으로 하는 중공사 분리막의 제조방법.
  3. 제1항에 있어서, 상기 외부 응고제를 이용한 응고 과정은 2단계로 실행하되 각 단계에서의 외부 응고제의 온도차가 80℃이하가 되도록 함을 특징으로 하는 중공사 분리막의 제조방법.
