磷元素在钛白粉表面处理及应用中的影响

Effect of Phosphorus on Surface Treatment and Application of Titanium Dioxide

研究了磷含量对钛白粉应用性能的影响,发现随着磷元素的增加,产品的打浆黏度升高,白度普遍升高,在应用涂料体系中光泽度先升再降,遮盖力逐渐升高,涂料白度无明显变化,而在乳胶漆体系中增加了遮盖力,对消色力也有明显提升。

This paper studies the effect of phosphorus content on the application performance of titanium dioxide. It has been found that whiteness rises along with phosphorus-increased pulp viscosity products and the gloss in the coatings system rises firstly and then drops; as the hidixg power gradually increases, the c.oatings whiteness does not change obviously; while the hiding power increases in the latex coatings system, the achromatic force rises significantly as well.
