| 摘 要： | 考察了聚合AlCl3制备过程的影响因素，得出了小试实验的最佳条件，研究了制备过程各因素的影响规律，结果表明：高岭土在650℃下焙烧3h，按3：1的摩尔比加入浓度为15%的盐酸，于85℃浸取5h,浸出率可达36.2%。聚合过程pH值控制在4.40，液态PAC碱化度达78.2%，产品质量明显优于目前市场上的同类产品质量指标。

| Abstract: | In this paper, the factors influencing preparation process of PAC have been investigated, the optimum condition for lab test have been obtained and the influencing rules for the factors in the process have been studied. The results show:At the temperature of 650 ℃ and by 3 hours torrefaction for kaolin, adding hydrochloric acid of 15% in concentration and 3∶1 in HCl/Al2O3mole ratio to it, after 5 hours soaking at the temperature of 85 ℃, the soaking ratio reaches to 36.2%; by controlling the value of pH at 4.40 in polymerization, the alkalinity of the liquor PAC is over 78.2%. |
