摘　　要：在固-液悬浮体系中固体颗粒的动电性质及动电电位(ζ电位)的测量研究中,显微电泳法是一种较好的测定方法,本文介绍了水泥颗粒在减水剂溶液中的动电电位测定研究结果,硅酸盐水泥在水溶液中的ζ电位为一8mv--10mv,随着萘系高效减水剂浓度的加大,水泥颗粒的ζ电位升高到-40mv--50mv;在木钙减水剂溶液中,只达到-15mv。The microelectrophoresis is proved to be a better way for determination of the electrokinetic property and ζ- potential of the solid grain in the solid - liquid suspension system. This paper gave a general introduction to its principle of determination and the testing results of ζ - potential when cement in the water and super water - reducer liquid.
