摘要: 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。 |

Abstract: An experimental study was carried out to investigate the technique of coating Mg(OH)2 on the surface of wollastonite by means of determining the isoelectric point of hydrous metal oxide.The factors which effect over the coating such as pH,concentration of Mg(OH)2 colloid,equilibrium time,liquid/solid weight ratio and so on.were determined.The better conditions are pH=10,colloidal concentration =1/mol·l-1,Taq=1h.The isoelectric point change regularlyalong with the change of Mg(OH)2 colloidal concetration was derived also.Thus a dependable method was supplied to predict the surface modification of some mineral. |
