试验通过在ZrO2颗粒悬浮液中添加分散剂聚丙烯酸(简称PAA)改变其剪切应力,研究了PH值变化、纳米粉体添加量和分散剂添加量对悬浮液剪切应力的影响。
In the experiment, the shear stress was changed by adding polyacrylic acid (PAA) as dispersant to the suspension of ZrO2 particles. The influence of the change of PH value, the amount of nano-powder and the dispersant dosage on the shear stress were studied.
