摘　　要：本文研究了聚电解质分散剂ＰＭＡＡ－ＮＨ４对ＺｎＯ悬浮体流变性的影响。结果表明：ｐＨ在９￣１０．５，分析剂用量为０．２￣０．３ｗｔ％时，ＺｎＯ悬浮体粘度最低。此条件下，可制得固相量达４３ｖｏｌ％（８１ｗｔ％）、粘度仅为２３７ｍＰａ·Ｓ的稳定悬浮体。In the paper, the effect of polyelectrolyte on the rheological properties of zinc oxide aqueous suspen　sion was studied.The results showed that the viscosity of suspension was lowest when the pH value between 9　to10. 5, and the amount of the disperat about 0.2 ~ 0.3wt%. At this condition, the viscosity of zinc oxide aqueous　suspension was only 237mPa·S while its volume fraction was 43 percent.
