Summarizing the difference between the performance of polymeric aluminum sulfate and polyaluminum chloride Summary Poly aluminum sulfate and polyaluminum chloride performance differences between the polymer flocculant What are the different types of polymeric flocculant different types and characteristics are not exactly the same, The main representatives of this group are polymeric aluminum sulfate and polyaluminum chloride, which can reflect the generality of polymeric flocculants. Since they are artificially made products, first of all, they have excellent morphology, and they are required to maintain their morphology after being put into the treated water and immediately exert the coagulation-flocculation effect. Therefore, the polymerization flocculant need strong or rapid mixing or scintillation mixing, long time the mixing reaction but rather redundant or unfavorable. Most of the traditional coagulant is a general salt, hydrolysis will occur after dosing, to hydrolyze the form or floc aggregation - flocculation process. Therefore, the original process of dissolution, mixing, reaction facilities often require longer residence time. Its operating parameters do not apply to polymeric flocculants. Polyaluminium sulphate and polyaluminum chloride are considered as more important and common agents, however, although both polymeric aluminum sulphate and polyaluminum chloride belong to the family of aluminum salts and also to iron salts, they have many salts However, since it is a kind of medicine, it shows that it must have its own difference. Compare the properties of polymeric aluminum sulfate and aluminum chloride. Compare the retention of the two, filter aid and sizing effect. The results show that polyaluminum chloride is a more effective cationic aggregator than polyaluminum sulfate. Well, we must understand that in the circumstances under which the polymeric aluminum sulfate can fully exert its effect and effect. The first is that the polymeric aluminum sulfate must be used under acidic conditions to be effective, causing corrosion of the papermaking system and poor durability of the paper . In addition, CaCO3 filler under acidic conditions will be chemical reaction CaO and CO2, resulting in a large number of foam, which can not be used, adding excess aluminum sulfate will precipitate the problem.
