近年来,国内聚合氯化铝生产急剧上升,主要用作净水剂,具有独特优良性能。聚合氯化铝的凝聚性能主要是由其碱化度和Al_2O_3含量所决定,碱化度太低,则氢氧根OH过少,不利于形成聚合体,而碱化度太高,则生成Al_2O_3沉淀,为水不溶物。因此生产过程中碱化度和Al_2O_3含量的控制对于聚合氯化铝的质量至关重要。目前,测定碱化度的方法有许多,有的
In recent years, the production of polyaluminum chloride has risen sharply in China, which is mainly used as purifying agent and has unique and excellent performance. Polymeric aluminum chloride agglomeration performance is mainly determined by its degree of alkalinity and Al 2 O 3 content, alkalinity is too low, the hydroxyl OH is too small, is not conducive to the formation of polymers, and the degree of alkalinity is too high, then generate Al 2 O 3 Precipitation, insoluble in water. Therefore, the control of the degree of alkalinity and Al 2 O 3 content in the production process is of crucial importance to the quality of polyaluminum chloride. At present, there are many ways to determine the degree of alkalinity, some
