摘要:研究了云母纸生产过程中水质（包括生产用水中各种金属阳离子、固体悬浮物以及pH值）对云母鳞片间作用力的影响。通过抄造的云母纸性能的变化进一步验证各种水质对云母纸强度的影响，并提出可用调节pH值、EDTA去除杂质离子、聚丙烯酰胺絮凝的方法改善水质，并取得了较好的效果，提高了云母纸的产品质量。

Abstract:Mica paper is broadly used as insulation material of electric industry, which is formed by electrostatic attraction and Van der Waals force. Influences of cations, SS and pH value of the process water on mica paper making are studied in this paper. The changes of mica paper properties proves the influences of water quality. Methods of improving the quality of water are proposed, which are adjustment of pH value, removing of cations with EDTA and removing of SS with polyacrylamide. Those methods have achieved good results, with upgrading the strength of mica paper.
