摘要： 利用Zetasizer Nano ZS 90 粒度仪、TURBISCAN Lab 专家型分散稳定性分析仪、透射电镜(TEM)3
种纳米粒径测量仪器, 研究了拟薄水铝石酸化胶溶过程中的溶胶粒径的变化规律及其影响因素。结果表明, 通过
Zetasizer Nano ZS 90 确定了拟薄水铝石酸胶溶的最佳酸铝物质的量比在0 .15～ 0 .30, 溶胶粒径在77 nm 左右;在相
同的胶溶条件下得到的拟薄水铝石溶胶, 利用TEM 测量得到的溶胶粒径值最小, 另外两种测量手段测定的溶胶粒
径值相差不大;增大酸铝物质的量比、提高胶溶温度都有利于胶溶反应的进行。

Abstract:

The change rule of sol size during the pseudo-boehmite peptization were explored by using experimental apparatus such as Zetasizer Nano ZS 90 , TURBISCAN Lab infrared dispersion steady indicator and TEM.The results show that the optimal range of [H+]/[AlOOH] molar ratio is 0.15 to 0.30, the sol size is about 77 nm. In the three kinds of pseudo-boehmite sol size measurement method, the smallest sol size measured by TEM, followed by the two others.Increase the [H+]/[AlOOH] molar ratio and peptization temperature are both in favor of peptization reactivity.
