Product Description
Polyaluminum chloride (PAC) is an inorganic substance, a new water purification material, inorganic polymer coagulant, referred to as polyaluminium. It is a water-soluble inorganic high molecular polymer between AlCl3 and Al(OH)3, the general chemical formula is [Al2(OH)nCl6-n]m, where m represents the degree of polymerization, and n represents the PAC product neutral level. n=1~5 is a highly charged polycyclic chain body with Keggin structure, which has a high degree of neutralization and bridging effect on colloids and particles in water, and can strongly remove micro-toxic substances and heavy metal ions, with stable properties. The inspection method can be inspected according to the national standard GB 15892--2003. Due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions, the produced polyaluminum chloride is an inorganic polymer water treatment agent with relatively large molecular weight and high charge.
The color is yellow or light yellow, dark brown, dark gray resinous solid. The product has strong bridging and adsorption properties. During the hydrolysis process, physical and chemical processes such as coagulation, adsorption and precipitation will occur. The fundamental difference between polyaluminum chloride and traditional inorganic coagulants is that traditional inorganic coagulants are low-molecular crystalline salts, while the structure of polyaluminum chloride is composed of polyvalent carboxyl complexes with variable shapes, and the flocculation and precipitation speed is fast, suitable for The pH range is wide, non-corrosive to pipeline equipment, and the water purification effect is obvious. It can effectively remove color SS, COD, BOD and heavy metal ions such as arsenic and mercury in water. This product is widely used in drinking water, industrial water and sewage treatment. field
Application:
It is widely used in industrial wastewater treatment, drinking water treatment, starch and alcohol loss recovery, papermaking additives, tertiary oil recovery and displacement agent, profile control and water blocking agent, drag reduction agent, drilling fluid additives, fracturing additives.
