摘　　要：海泡石的表面电性对加工及开发应用有很大的影响 ,因此有必要对海泡石的表面电性进行研究。本文考察了纤维状及土状海泡石原料的 ζ电位 ,以及悬浮液酸度、分散剂种类、不同加工方法、阳离子活性剂用量等因素对ζ电位的影响 。The surface electrical property of sepiolite has great influence on the processing process and exploitation of sepiolite. The influences of some major factors,such as the ζ potential of fibrous and clayed sepiolite raw materials,the acidity of suspension,the kinds of dispersers,the processing methods and the dosage of cationic surfactant etc. on surface electrical property of sepiolite were examined,and their reasons are briefly explored in this paper.
