摘要: 从包覆成膜时热力学所决定的包膜量以及工艺本身引入的盐分对包膜量的影响出发,分别探讨了TiO₂表面包覆致密SiO₂膜的最小包膜量与最大包膜量;同时进行TiO₂表面包覆不同量SiO₂时实验样品的酸溶性、吸油量、消色力、白度等性能的研究,在此基础上,确定了TiO₂表面包覆致密SiO₂适宜的包膜量。

Abstract: Infulence of thermodynamics and salinity as agent on film formation are discussed,the minimum and maximum coating quantity of compact SiO₂ on the surface of TiO₂ are pointed out in this paper.On the basis of the analysis,coating test with different quantities of SiO₂ on the surface of TiO₂ are carried out and applicable properties of samples in these tests have been detected including acid solubility,oil absorption value,tint-reducing power,whiteness.Then the optimum coating of sillica on surface of TiO₂ is found.
