Since polyaluminum chloride can be regarded as an intermediate product in the process of gradually hydrolyzing AlCl3 into Al(OH)3, that is, various products in which Cl- is gradually substituted by hydroxy OH-. The degree of hydroxylation in a certain form of polyaluminum chloride is the degree of alkalization, which is the ratio of the hydroxyl equivalent of the polyaluminum chloride to the equivalent of aluminum.

 

Practice has shown that the degree of alkalization is one of the most important indicators of polyaluminum chloride. The degree of polymerization, charge, coagulation effect, pH value of the finished product, dilution rate during use, and storage stability of the polyaluminum chloride are all It is closely related to the degree of alkalization. The degree of alkalization of commonly used polyaluminum chloride is usually 50% to 80%.
