摘　　要：本文研究了分散剂种类及数量、pH值对陶瓷微滤膜涂膜液分散性能的影响,找出了适宜的分散剂及其使用条件。结果表明:在pH=9～11时,加入0.2wt%～0.8wt%的PAA,制出的涂膜液具有良好的稳定性。In this paper, the influence of different kinds and contents of dispersants and pH values of membrane suspensions on the stabilities of the suspensions were studies. The suitable dispersants and the utilizing conditions were obtained(pH=9～11, 0.2～0.8wt%PAA), which can well disperse suspentions for ceramic microfiltration membranes.
