Polyaluminium chloride is a kind of inorganic polymer flocculants , abbreviations for PAC. Due to the effect of bridge of the hydroxyl ions and polyvalent anions polymerization production, charge higher molecular weight of inorganic polymer water treatment agent.
Poly aluminum Chloride referred to as PAC. Often called Basic or a coagulant such as aluminum chloride, which is between ALCL3 and AL (OH) 3 ,as a water-soluble inorganic polymers, the chemical molecular is [AL2 (OH) NCL6 - NLm] ,where m on behalf of polymerization degree, n said that the neutral level of PAC products. The color is yellow or light yellow, dark brown, dark gray resin-like solid. The product has a strong bridge adsorption performance, during the hydrolysis process, Occurs with cohesion, adsorption and precipitation and other physical chemical processes.
