摘要

摘要: 研究了TiO₂颗粒"打浆分散-砂磨"组合工艺分散技术。采用黏度和粒度表征TiO₂颗粒的分散状况,通过透射电镜观察分散前后TiO₂颗粒大小和形貌的变化情况。探讨了分散剂种类、分散剂加量、砂磨介质粒径和砂磨时间对TiO₂颗粒分散效果的影响。结果表明,TiO₂颗粒的最佳分散工艺为:硅酸钠作为分散剂,添加量为TiO₂质量分数的0.2%,采用粒径为0.4μm的氧化锆珠砂磨25 min,平均粒径为265 nm,粒度大小均匀,分散效果稳定。

Abstract: The "dispersing and grinding"combined process was studied for dispersing TiO₂.The dispersity of TiO₂ particles was characterized as viscosity and particle size.The particle size and morphology of TiO₂ before and after dispersing were observed using TEM.Effects of the dispersing agents and their addition amount,the size of grinding medium and grinding time on the dispersion of TiO₂ were discussed.The results show that the optimum process conditions for dispersing TiO₂ are as follows:sodium metasilicate as the dispersing agent with addition amount of 0.2%(mass ratio) for TiO₂,ZrO₂ as grinding medium with size of 0.4 μm and 25 min of the grinding time.The average particle size of TiO₂ obtained under the optimum conditions is 265 nm with uniform particle size distribution and steady dispersing effect.
