Abstract

소수성 수지로 된 분리막으로 형성시키는 경우 현저하게 발수성이 되어 분리막이 물과 친화성이 없어지기 때문에 투과선능을 충분하게 발휘하지 못하고 제약이나 식품공업 등에서 적용시 분리물질의 흡착 등으로 인해 투과성능이 운전중에 크게 감소하게 된다. 특히 건조가 발생되면 수투과성능이 현저하게 감소하여 실지 적용시에 많은 문제점을 노출하게 된다.In case of forming a membrane made of a hydrophobic resin, the water repellency is remarkably water-repellent and the membrane is not compatible with water, so the permeation performance is not sufficiently exhibited. Greatly reduced. In particular, when the drying occurs, the water permeation performance is significantly reduced to expose a number of problems in practical applications.

따라서 본 발명에서는 친수화된 소수성수지로 제조된 분리막에 대한 것으로서, 중공사막을 염기성 수용액에 침지하거나 열처리하여 친수성 물질을 막의 표면, 이면 및 내부에 고르게 부착시켜 영구적으로 친수화시킴으로써 막의 투과성이 건조시나 장기 운전시에도 충분히 발휘될 수 있도록 하기 위한 소수성수지로 제조된 한외여과용 건조분리막의 제조방법에 대한 것이다.Therefore, the present invention relates to a membrane made of a hydrophilized hydrophobic resin, the hollow fiber membrane is immersed in a basic aqueous solution or heat treated to evenly attach the hydrophilic material to the surface, back and inside of the membrane permanently hydrophilized by drying the permeability of the membrane The present invention relates to a method for manufacturing a dry separator for ultrafiltration made of a hydrophobic resin to be sufficiently exerted even in long-term operation.
