聚合氯化铝 Polyaluminum chloride

   Polyaluminum chloride (PAC) is an inorganic substance, a new water purification material and inorganic polymer coagulant, which is called polyaluminum for short. It is a water-soluble inorganic 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 neutrality of PAC products. N=1~5 is a highly charged polymer 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 micro poisons and heavy metal ions, with stable properties. The inspection method can be tested according to the national standard GB 15892--2003. Due to the bridging effect of hydroxyl ions and the polymerization of multivalent anions, polyaluminum chloride produced is an inorganic polymer water treatment agent with relatively large molecular weight and high charge.

   Polyaluminum chloride has the properties of adsorption, condensation, precipitation and so on. Its stability is poor and corrosive. If it is accidentally splashed on the skin, it should be immediately rinsed with water. Production personnel should wear work clothes, masks, gloves and long rubber boots. Polyaluminum chloride has the advantages of good spray drying stability, wide adaptability to water area, fast hydrolysis speed, strong adsorption capacity, large alum formation, fast dense sedimentation, low effluent turbidity and good dehydration performance. Using spray drying products can ensure safety, reduce water accidents, and is very safe and reliable for residents' drinking water. Therefore, polyaluminum chloride, also known as high-efficiency polyaluminum chloride, high-efficiency PAC or high-efficiency spray drying polyaluminum chloride. Polyaluminum chloride is suitable for raw water with various turbidity and a wide range of pH
