By SEM, different component have great effect on flocculent structure. Zn have trend to form network, Al and Mg form sheetlike to around. Structure characterizations of PSAZ and PSMZ is different of common IPF, it has nicer flocculation efficiency and stability.

扫描电镜分析表明不同组分对絮凝剂结构具有较大的影响，发现增加锌的含量，有利于生成网状物，铝、镁的向四周发展的片状结构，聚硅酸铝锌和聚硅酸镁锌的结构不同于一般的絮凝剂，其特殊的片状结构决定了絮凝的优良的絮凝效果。
