分相膜的结构及它的分相性能

THE STRUCTURES OF TWO MEMBRANES OF PHASE SEPARATION AND THEIR CHARACTERISTICS FOR PHASE SEPARATION

本文用SEM 方法研究两种亲水膜的结构;用激光全息照相法测定亲水膜表面的纯水层厚度(t),还试验了这两种膜的除油效果。结果表明:分相膜的结构对纯水层厚度(t)和除油效果有影响,这对深入进行膜分相的机理研究和应用研究有重要意义。

In this paper,the structures of two hydrophilic membranes of phaseseparation were investigated by SEM,the thickness of pure water (t) on themembrane surface were measured by laser holography and oil-removingefficience of two membranes were tested.The results show that the thick-ness of pure water and oil-removing efficience are affected by the structuresof the hydrophilic membranes.These experimental results are very usefulfor both of futher study on the mechanism of membrane phase separationand applied study of the technique.
