硅灰石表面改性实验研究

Study on Surface Modification of Wollastonite

实验以湖北大冶硅灰石为原料 ,初步探讨了硅灰石表面改性的工艺条件。经沉降体积法、表面接触角、红外光谱等方法检测和填充橡胶试验证实 ,硅灰石得到了改性且其填充性能有明显的提高。

In this article, the processing conditions of surface modification of Hubei Daye wollastonite are studied. The modified wollastonite is evaluated by some measurement methods such as sedimentation height in different solvent medium, surface contact angle method, infra red spectrometry and rubber packing test. The results indicate that the wollastonit is modified effectively and the filling performances of the modified wollastonites are greatly improved, which has been verified by the application experiments.
