摘要
总结了钛白粉白度的表示方法,介绍了甘茨白度、蓝光白度和亨特白度。另外,对影响钛白粉白度的因素,如杂质、粒径和粒度分布、颗粒形状和钛含量等做了研究。最后列举了对生产的指导,如选择好矿、改进水解方法、控制砂磨机气粉粒径等。
This paper summarizes the representation method of the whiteness of titanium dioxide, and also introduces Ganz whiteness, blue whiteness and Hunter whiteness. In addition, the factors affecting the whiteness of titanium dioxide are studied. including impurities, particle size and its distribution, particle shape and titanium dioxide content. The guidance for the production, such as how to select a good ore, to improve the hydrolysis method and to control the particle size of the sand mill are proposed.
