摘　　要：用透射电镜观察比较了聚硅氯化铝(PASC)与聚合氯化铝(PAC)混凝剂的结构形貌,探讨了碱化度(B)、Al/Si摩尔比、及制备工艺对PASC结构形貌的影响。研究结果表明,PASC较PAC具有更大的聚集度和枝化度。PASC的聚集度随B值的升高和Al/Si摩尔比的降低而增大;共聚法制备的PASC较复合法制备的PASC具有更大的聚集度。Morphology of polyaluminum silicate chloride (PASC) flocculant and polyaluminum chloride(PAC) has been studied and compared by transmission electron microscope(TEM). Effect of basicity(B), Al/Si molar ratio and preparation procedure on morphology of PASC were also investigated. The experimental results showed that the size of PASC was larger than that of PAC. The size of PASC increased with increasing of B value and decreasing of Al/Si molar ratio. In comparison with PASC products prepared by composite technique, PASC products prepared by copolymerization technique were characterized by having bigger size.
