Introduction:
Polyaluminum chloride is a kind of water purification material, inorganic polymer coagulant, also referred to as polyaluminum, and the English abbreviation is PAC. The molecular weight is produced due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions Larger, higher charge inorganic polymer water treatment agent. In terms of form, it can be divided into solid and liquid. The solid is divided into brown, beige, golden and white according to different colors. The liquid can be colorless and transparent, slightly yellow, light yellow to yellowish brown. Different colors of polyaluminum chloride also have big differences in application and production technology.
