滤布的过滤性能试验研究

以4种常用工业滤布为过滤介质，分别进行了透过空气、清洁水和酞氰蓝染料悬浮液的渗透性试验，测得了滤布的透气阻力、透水阻力和透过悬浮液的过滤介质阻力，并推出了它们之间的关系。通过悬浮液的过滤试验，提出了一种理论预测滤布的颗粒截留能力的方法。

An Experimental Investigation on the Performance of the Filter Cloths

The osmosis tests of the air osmosis,of the clean water osmosis, of the suspension liquid osmosis of phthalocyanine dye were separately made with the filter medium of the four common industry filter cloths,and the air resistance, the water resistance,the suspension liquid resistance to the filter cloths were measured.The relation between them was pointed out,a method was proposed of predicting the trap ability of the filter cloths for particles in theory through the fiher test of the suspension liquid.
