The effect of post- heating temperature and time on tee ooating thickness of phosphates TiOA and PNP9 on the surface of talc and the relationship between the coating thickness and phosphate concentration were studied by quantitative Drifts analysis.

• 应用DRIFTS定量分析方法考查了热处理温度和时间对磷酸酯T10A和PNP9在滑石粉表面包覆量的影响；以及磷酸酯用量与包覆量的关系.
