Alumina Chloride (PAC)

Polyaluminum Chloride (PAC) is an inorganic substance and a new type of water purification material.Inorganic polymerCoagulant, commonly referred to as polyaluminum. It is an intermediate product between AlCl3With Al(OH)3A water-soluble inorganic polymer, chemical formula [Al]2(OH)nCl6-n]m, whereinmRepresents the degree of aggregation.nIndicates the neutrality of PAC products.n1-5 are highly charged polycyclic ring chains with Keggin structure, which exhibit strong electro-neutralization and bridging effects on colloids and particulates in water, and can effectively remove trace toxicants and heavy metal ions. They are characterized by stable properties. Inspection methods can be carried out according to the national standard GB 15892-2003. Due toHydroxide ionThe bridging effect and aggregation of polyvalent anions contribute to the production of polymerized aluminum chloride, which is an inorganic polymer with a relatively high molecular weight and charge.Water Treatment Agent。
