Title
(JA) ろ過用微多孔膜、その製造方法、扁平なろ過材、及びガスろ過用品
Abstract
(JA)

本願は、構造が均一な高通気性のろ過用微多孔膜、扁平なろ過材、及びガスろ過用品を提供し、前記微多孔膜は、ポリエチレン100−110重量部、アクリロニトリル27−30重量部、ジクミルペルオキシド0.1−0.2重量部、可塑剤2−4重量部、三酸化アンチモン1−2重量部、ホウ酸亜鉛0.8−1重量部、酸化防止剤1−2重量部、熱安定剤0.8−2重量部、オクチルイソチアゾリノン1−2重量部、プロピオン酸カルシウム1−3重量部、イソシアヌル酸トリグリシジル0.7−2重量部、ジアセトンアルコール4−6重量部、オレイン酸ジエタノールアミド0.7−1重量部、ミリスチン酸ナトリウム石鹸0.5−1重量部及びグリコール酸1−2重量部から製造される。本願のプロセス技術は、従来の他のプロセスに比べて、プロセスが簡単で、生産量が高く、大規模な連続生産に適し、効果的な生産性は製造コストが低減される。且つ、ポリオレフィンを採用するため、原料が安価であり、最終的にガスろ過膜のコストが大幅に低下される。
