Abstract

소수성 수지로 된 분리막으로 형성시키는 경우 현저하게 발수성이 되어 분리막이 물과 친화성이 없어지기 때문에 투과성능을 충분하게 발휘하지 못하고 제약이나 식품공업 등에서 적용시 분리물질의 흡착등으로 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 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. When applied in pharmaceuticals or food industry, the permeation performance is operated due to adsorption of the separation material. 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 폴리술폰으로 제조된 분리막에 대한 것으로서, 중공사막을 퍼술페이트 금속염에 침지하여 친수성 물질을 막의 표면, 이면 및 내부에 고르게 부착시켜 영구적으로 친수화시킴으로써 막의 투과성이 건조시나 장기 운전시에도 충분히 발휘될 수 있도록 하기 위한 폴리술폰으로 제조된 한외여과성 건조 분리막의 제조방법에 대한 것이다.Therefore, the present invention relates to a membrane made of hydrophilized polysulfone, the hollow fiber membrane is immersed in a persulfate metal salt to attach the hydrophilic material evenly to the surface, the back and the inside of the membrane permanently hydrophilized by permanently hydrophilic, so that the permeability of the membrane during drying or long-term The present invention relates to a method of manufacturing an ultrafiltration dry separator made of polysulfone so as to be sufficiently exerted even during operation.
