由钠型蒙脱土悬 浮体和水解聚丙烯酰胺组成的体系有负触变现象, 对负触变性的形成条件和影响因素作了初步探讨. 并对微观结构作了一些推测.

关键词: 聚丙烯酰胺, 悬浮体, 蒙脱石, 触变性

The fluidity and thixotropy of montmorillonite suspensions containing added hydrolyzed polyacrylamide show unusual thixotropic behavior in that they show in their natural state a neg. thixotropy (the fluidity of the suspensions increases with time). This neg. thixotropic behavior is time-dependent and exhibits clockwise hysteresis loops. The consistency of the suspension has a considerable influence on this unusual behavior and addns. of salts destroy the ability of the materials to build up a structure possessing a neg. thixotropic behavior.

Key words: POLYACRYLAMIDE, SUSPENSION, MONTMORILLONITE, THIXOTROPY
