本工作用锡和锌两种溶胶对硅灰石进行表面处理。用酸碱测定、X-射线光电子能谱(XPS)、傅里叶变换红外光谱(FT-IR)、粒度分析、比表面测定和扫描电子显微分析(SEM)等方法研究了溶胶处理对硅灰石表面化学性质和物理性质的影响情况。结果表明经过溶胶处理,锡或锌是以氧化物的形式包覆在硅灰石的表面,使得硅灰石的表面组成、形貌和酸碱性都发生了变化。
This work with tin and zinc two sol on wollastonite surface treatment. The effect of sol treatment on the surface of silicon was studied by acid-base determination, X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FT-IR), particle size analysis, surface area measurement and scanning electron microscopy (SEM) The influence of the chemical and physical properties of the surface of the graystone. The results show that after sol treatment, tin or zinc is coated on the surface of wollastonite in the form of oxide, which changes the surface composition, morphology and acid-base of wollastonite.
