摘要
研究了用液相沉积法在高岭土颗粒表面包覆二氧化钛膜的工艺。结果表明 ,改性温度和改性时间、基体悬浮液浓度、搅拌速度和煅烧温度是影响包覆效果的关键因素。运用遮盖力对最终产品进行测试 ,当在高岭土表面包覆一定厚度二氧化钛膜时 ,可大幅度地提高高岭土的遮盖力 。
The technology of coating TiO 2 film on the surface of kaolin p articles was studied by liquid deposition method.It is shown that the reaction temperature,reaction time,pulp density,stirring velocity and calcination temperature are the important factors influencing the effect of the coating.Use covering property to test the coating product.The results showthat titanium dioxide film on the kaolin powder can greatly improve the covering property of kaolin.It can supply reference for the coating product as a substitute for titanium white.
