초록

Melt-blown 섬유 방사시스템을 사용하여 수처리용 폴리프로필렌(polypropylene, PP) 카트리지 전처리 필터를 제조하였다. Melt-blown 섬유 방사시스템의 공정인자들이 폴리프로필렌 카트리지 전처리 필터의 섬유구조와 충진밀도에 미치는 영향을 고찰하고자 하였으며, 공급 공기분출속도와 고분자 토출량(polymer throughout rate, g/hole/min) 등과 같은 melt-blown 공정인자들을 변화시켜 제조된 폴리프로필렌 필터소재의 여과특성 변화를 연구하였다. Single 노즐이 장착된 melt-blown 섬유 방사시스템에서 고분자 토출량이 감소할수록, 공급 공기분출속도가 증가할수록 폴리프로필렌 방사 섬유의 직경이 감소하였다. 실험 결과, melt-blown 섬유 방사시스템에서의 공정인자를 조절함으로써 melt-blown 섬유 방사시스템에 의해 제조되는 수처리용 폴리프로필렌 카트리지 전처리 필터의 평균기공크기와 여과특성 조절이 가능함을 알 수 있었다.

A polypropylene(PP) cartridge pre-filter media for water purification was obtained from a melt-blown extrusion method. The effect of melt-blown processing conditions on the fiber structure and the packing density of polypropylene cartridge filter element were investigated. And the filtration characteristics of them made in the various conditions of the melt-blown processing parameters, such as the air velocity and polymer throughout rate, were studied. The fiber diameters of what made with the melt-blown extrusion method which was equipped the single-nozzle decreased as the air velocity increased, however increased as the polymer throughout rate increased. The experimental results show the possibility of controling the mean pore size and filtration characteristics of polypropylene (PP) cartridge filter element for water purification with controlling of the processing conditions using the melt-blown extrusion method.
