碱化

In addition, the interaction between polysilicic acid and hydrolysis aluminum species in PASiS was discussed.

水处理实验结果表明，PASiS的絮凝效果优于PAC，PAS，PASC和PAM等絮凝剂，而又以共聚法制备的PASiS的絮凝效果更佳；不同碱化度、硅酸聚合度及铝硅摩尔比的PASiS表现出不同的絮凝性能，吸附架桥及捕获沉淀是其主要絮凝机理。

The experimental results show that the interaction between polysilicic acid characterized negative charge and hydrolyzed aluminum species results in the decrease in the charge-neutralizing ability of PASC, in comparison with PAC.

研究结果表明，在 PASC 中，由于带负电荷的聚硅酸与铝水解聚合产物间的相互作用，使得 PASC 的电中和能力较 PAC 有所下降，其下降程度与 PASC 的碱化度和 Al/Si 摩尔比密切相关，B 值和 Al/Si 摩尔比越小，则 PASC 的电中和能力就越弱。

The research conclusions above mean that polysilicic acid can react with hydrolyzed aluminum species to form aluminum-silicate polymer composite, which made the species distribution in PASC changed.

但对PASC而言，情况有所不同，在低碱化度和低Al/Si摩尔比情况下，Al13和Alb之间不存在对应关系，Al13和Alb比值远远小于1.0，随着B值和Al/Si摩尔比的升高，Al13/Alb比值逐渐趋近于1.0。
