本文通过Ｚｅｔａ电位和流变性能的测量，研究了ｐＨ值及聚合物电解质对纳米Ｙ－ＴＺＰ粉体浆料分散的影响。结果表明，Ｙ－ＴＺＰ的Ｚｅｔａ曲线呈正弦波形式，在等电点附近，浆料易产生聚沉，在强酸强碱性条件下也不利于浆料的分散。综合考虑Ｚｅｔａ电位、沉降高度及粘度等流变行为，认为高Ｚｅｔａ电位是获得稳定浆料的必要条件，加入ＤａｒｖａｎＣ（聚甲基丙烯酸氨）可显著提高浆料的Ｚｅｔａ电位及碱性条件下的稳定性，通过运用静电位阻稳定机理，可获得分散良好的浆料。
In this paper, the influence of pH value and polymer electrolyte on the dispersion of nano-Y-TZP powder slurry was studied by measuring Zeta potential and rheological properties. The results show that the Zeta curve of Y-TZP is in the form of a sine wave. The slurry tends to aggregate near the isoelectric point and is not conducive to the dispersion of the slurry under strong acid and alkaline conditions. Taking Zeta potential, sedimentation height and viscosity into account, the high Zeta potential is considered as a necessary condition to obtain stable slurry. Addition of DarvanC (ammonia polyacrylamide) can significantly increase the Zeta potential of the slurry and alkaline conditions Stability, through the use of electrostatic steric stabilization mechanism, you can get decentralized slurry.
