摘　　要：研究了聚合硅酸硫酸铝对高岭土悬浮液的絮凝性能。结果表明,聚合硅酸硫酸铝对高岭土悬浮液具有极好的絮聚作用,其絮凝效果与聚合硅酸硫酸铝的碱化度、加入量和高岭土悬浮液的pH值有关;其絮凝机理主要为吸附架桥与卷扫等作用。The flocculation and coagulation of polyaluminum silicate sulfate on kaolin suspension is investigat-ed.The results show that polyaluminum silicate sulfate can cause very effective flocculation/coagulation of kaolin suspension,which is affecte d by the basicity and dosage of polyaluminum silicate sulfate as well as the pH of the kaolin suspension.The mechanism of flocculation/coagulation is related to absorption,bridging and sweeping of polyaluminum silicate sulfate on kaolin particles.
