Product Description

Product Description

Polyaluminum chloride (PAC) is an inorganic substance, a new water purification material and inorganic polymer coagulant, which is referred to as polyaluminum for short. It is a water-soluble inorganic polymer between AlCI3 and Al(OH)3, and its general chemical formula is [Al2(OH)nCl6-n]m, where M represents the degree of polymerization and N represents the neutral degree of PAC products. N=1~5 is a highly charged polymeric ring chain with Keggin structure, which has a high degree of electric neutralization and bridging effect on colloids and particles in water, and can strongly remove trace poisons and heavy metal ions, with stable properties. The inspection method can be according to the national standard GB 15892--2003. Due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions, the produced polyaluminium chloride is an inorganic polymer water treatment agent with higher molecular weight and higher charge.

 

The raw materials of yellow polyaluminium chloride are calcium aluminate powder, hydrochloric acid and bauxite, which are mainly used for sewage treatment and drinking water treatment. The raw materials used for drinking water treatment are aluminum hydroxide powder, hydrochloric acid and a little calcium aluminate powder. The process adopted is plate-frame filter pressing process or spray drying process. For the treatment of drinking water, the state has strict requirements on heavy metals, so both raw materials and production technology are better than brown polyaluminium chloride. Yellow polyaluminium chloride is generally produced by roller drying or spray tower drying, and has two solid forms: flake and powder.
