| 摘 要： | 过滤介质的透水实验表明 ,清洁过滤介质的透水速率随时间延长而降低。水中所溶解的气体会吸际于过滤介质的纤维表面 ,并将滤布的孔隙堵塞 ,从而使过滤介质的透水速率逐渐降低。过滤介质的孔隙越小 ,纤维的疏水性越强 ,此现象越明显。

| Abstract: | The results of a series of permeation experiments prove that the permeation rate of clean filter media decreases with the permeation time increaese.Soluble air bubbles in non ion water absorb on surface of fibres woving filter media and clug proes in filter media,so that the permeation rate decreases.The phenomenon is much more obvious for the mini pore filter media woven by hydrophobic fibres. |
