摘　　要：以含铝矿和工业水玻璃为主要原料,制备一系列Si∶Al∶Fe摩尔比不同的聚硅酸铝铁钙(PSiAFCC)絮凝剂.采用化学分析方法及热重分析、扫描电镜等手段对该絮凝剂进行了性能表征,并对PSiAFCC中聚硅酸与铝、铁之间的相互作用、结构形貌及热稳定性进行了全面对比研究.结果表明,PSiAFCC是一种性能优良的絮凝剂.A series of PSiAFCC flocculants with different ion molar ratio of silica, aluminum and iron were prepared through the ores containing aluminum and the industrial water glass. Some advanced methods were used to measure the characteristics of PSiAFCC, such as chemical analysis, thermogravimetric analysis and SEM, etc.Also, some topics were discussed in this paper, including the inter-action of poly-silicic acid, aluminum and iron, structural topography and heating stability.The results show that PSiAFCC is one kind of great flocculants with good characteristics.
