| 摘 要： | 分析了钛白粉体在水中的分散机理,用重力沉降法研究了钛白粉体在水溶液中pH、粉体粒度分布、分散剂种类、分散剂加入数量等因素对钛白粉水分散性的影响。调节钛白浆料的pH在7.0以下,7.0~7.9,8.0~9.0,9.1~11.0,11.0以上这5个范围,得到分散性较好的pH范围在8.0~11.0。通过研究3种钛白粉体粒度对分散性的影响,发现粒度越小,分散性越好。通过研究分散剂六偏磷酸钠、铝酸钠、三羟甲基丙烷、无水乙醇、六偏磷酸钠+聚乙二醇(按体积比为1∶1)、六偏磷酸钠+无水乙醇(按体积比为1∶1)等6种分散剂的分散效果以及最佳分散剂的加入量,得出六偏磷酸钠+无水乙醇(按体积比为1∶1)的分散性最好,其最佳加入量为0.5%(质量分数)。

| Abstract: | Dispersion mechanism of titanium dioxide in water was analyzed.Influences of the factors,such as pH value of titanium dioxide powder in aqueous solution,powder particle size distribution,and type and dosage of dispersing agent on water dispersion of titanium dioxide powder were studied by gravity sedimentation method.Through adjusting pH values of the slurry of titanium dioxide in the ranges of 7.0 below,7.0~7.9,8.0~9.0,9.1~11.0,and 11.0 above,it was obtained that the pH range for better dispersion was at 8... |
