本工作用测定水合金属氧化物等电点的方法,作为评定在硅灰石表面镁的包膜技术,为硅灰石的一物多用提供了新的途径;亦为在硅灰石表面包覆其他金属氧化物找到了一种新的方法。 本工作还研究了影响镁包覆的几种因素,结果表明,在硅灰石表面镁包膜的最佳条件为:pH=10,氢氧化镁溶胶的浓度为0.1mol·1~(-1),平衡时间为1小时,液固质量比为10以上。
This work hydrometallurgical determination of isoelectric point method, as the evaluation of the surface of the wollastonite coating technology for the wollastonite a multi-purpose provides a new way; also covered in wollastonite surface Other metal oxides found a new way. The results showed that the optimal conditions of magnesium coating on the surface of wollastonite were: pH = 10, the concentration of magnesium hydroxide sol was 0.1mol · 1 ~ (-1) ), The balance time of 1 hour, liquid-solid mass ratio of 10 or more.
