Abstract

구금의 외부에는 소수성 수지, 첨가제, 용매로 이루어진 방사원액을, 내부에는 용매. 물로 이루어진 내부 응고제를 토출, 방사하여 외부응고제에 침적시켜 중공사 형태의 분리막을 제조하고, 상기 분리막을 세정액으로 세정하고 연속적으로 친수화제 처리, 가교제 처리한 후 권취하여 중공사막을 제조하고, 상기 중공사막을 열처리하여 제조되는 소수성 수지계 건조 분리막은 건조시에도 투과성능이 우수하고, 파울링이나 농도분극 현상이 기존 소수성 분리막에 비해 크게 개선되어 단백질이나 유기물이 많이 존재하는 수용액 처리시나 장기 운전시에도 충분히 발휘될 수 있는 우수한 소수성 수지계 건조 분리막이다.The spinneret is composed of a hydrophobic resin, an additive, and a solvent on the outside of the detention, and a solvent on the inside. The internal coagulant made of water was discharged and spun and deposited on the external coagulant to prepare a hollow fiber-type separator, and the membrane was washed with a washing solution, and subsequently treated with a hydrophilic agent, a crosslinking agent, and wound to prepare a hollow fiber membrane. The hydrophobic resin-based dry membrane produced by heat treatment of the desert has excellent permeability even during drying, and fouling and concentration polarization are greatly improved compared to the existing hydrophobic membrane, so that it is sufficient even when treating an aqueous solution containing a lot of protein or organic matter or during long-term operation. It is an excellent hydrophobic resin-based dry separator that can be exerted.
