On the basis of the analysis,coating test with different quantities of SiO_2 on the surface of TiO_2 are carried out and applicable properties of samples in these tests have been detected including acid solubility,oil absorption value,tint-re- ducing power,whiteness.
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TiO_2表面包覆致密SiO_2膜的最小包膜量与最大包膜量;同时进行TiO_2表面包覆不同量SiO_2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TiO_2表面包覆致密SiO_2适宜的包膜量。
The advantages of the agent are: good plugging,easy usage,high acid solubility,and so on,and can be used for formation damage.
