采用分散法工艺制备了高浓度超细二氧化硅水性分散系，对分散系中粒子的表面Ｚｅｔａ电位以及分散系的流变行为进行研究，结果表明，采取母液法和高ｐＨ值的分散介质可以得到高度分散、高度稳定的胶态分散系。
The disperse method was used to prepare the aqueous dispersion system of high concentration ultrafine silica. The surface zeta potential of the dispersion and the rheological behavior of the dispersion system were studied. The results showed that the dispersion medium with mother liquor and high pH could Get highly dispersed, highly stable colloidal dispersion.
