空气过滤用滤材、过滤包、空气过滤单元、及空气过滤用滤材之制造方法
摘要
本发明提供一种维持较高之捕获效率并且保尘量大幅度提高之空气过滤用滤材、过滤包、空气过滤单元、及此种空气过滤用滤材之制造方法。;本发明之空气过滤用滤材具备主要包含氟树脂之第1多孔膜及第2多孔膜。第2多孔膜系配置于较第1多孔膜更靠气流之下游侧。第1多孔膜于使包含个数中值粒径0.25μm之聚α-烯烃粒子之空气以流速5.3cm/秒连续通风而压力损失上升250Pa时之聚α-烯烃粒子之保尘量大于第2多孔膜。空气过滤用滤材之特征在于:压力损失未达200Pa,粒径0.3μm之NaCl粒子之捕获效率为99.97%以上,且个数中值粒径0.25μm之聚α-烯烃粒子之保尘量为25g/m 2 以上。
