项目摘要
The present work is aimed at developing and proposing the testing methods on performance of various membrane filters for dilute liquidborne particles with diameter of submirometer. Particle panetrations of membrane filters with various structures were measured with light-scattering type particle counters. Major conclusion obtained by this work are ;1. Interception effect acts on the filtration of particles with diamter smaller than the pore size of membrane filters.2. Since the difference of porosity among filters can have influence on the shape of electrostatic double layr around their collection body in deionized water system.3. For fiber-like membrane filters, particle penetration are subject to decrease because high ion concentration of filtration liquid compresses the electrostatic double layr around their collection body.These understandings suggest that it is necessary to introduce a new index accounting for physical properties such as fiber diameter, packing density and filter thickness instead of pore size rated by the bubble point method in order to predict their collection efficiency for particles with diameter smaller than the pore size.
目前的工作旨在开发和提出有关各种膜过滤器的性能的测试方法,以稀释液体颗粒,并直径为含量计。用光散射类型的粒子计数器测量具有各种结构的膜过滤器的颗粒化。这项工作获得的重大结论是; 1。截距效应作用于小于膜过滤器的孔径的颗粒的过滤2。由于过滤器之间的孔隙率差异可能会影响静电系统周围静电双层的形状。3。对于纤维样膜过滤器,颗粒渗透会导致降低,因为过滤液的高离子浓度压缩了静电双层液体周围的静电双层。这些理解表明,有必要在物理特性中引入新的索引,以征收纤维直径,诸如填料密度和孔径较大的孔径的尺寸,而不是孔子尺寸的尺寸,而不是孔的尺寸,以预测其收集量,以预测其较大的收集效率。
