Polyaluminium chloride(pac), referred to as high-efficiency polyaluminium chloride, or high-efficiency PAC. The most advanced production technology is adopted and high-efficiency high-quality raw materials are used for reaction polymerization. The production shall be carried out in accordance with the requirements of national standard gb15892-2009. Polyaluminium chloride is processed by spray drying process, so it can also be called high efficiency spray drying polyaluminium chloride.
Due to the good stability of spray drying, the PAC has the advantages of wide adaptability to water, fast hydrolysis speed and strong adsorption capacity, and has the advantages of large alum, dense and precipitated precipitates, low turbidity and good dewatering performance. Under the same water quality, the dosage of spray drying polyaluminum chloride is reduced, especially under the condition of poor water quality. The volume of spray drying products can be reduced by half compared with that of the drum drying polyaluminum chloride, which not only reduces the labor intensity of workers, but also more importantly, reduces the user’s water production cost. In addition, spray drying products can ensure safety and reduce water accidents, which is very safe and reliable for drinking water.
Polyaluminium chloride is an inorganic polymer flocculant. Inorganic polymers with high molecular weight and high charge are produced by the action of hydroxyl ion functional groups and multivalent anion polymerization functional groups. The adaptable pH value range is 5.0-9.0, and the optimal pH value is 6.5-7.6
It can be applied to the treatment of river water, lake water and groundwater; Treatment of industrial water and industrial circulating water; Wastewater treatment, coal mine scouring wastewater and porcelain industry wastewater recovery; Printing plants, printing and dyeing plants, leather factories, breweries, meat processing plants, pharmaceutical factories, paper mills, coal washing, metallurgy, mining areas, as well as the treatment of wastewater containing fluorine, oil and heavy metals; Wrinkle resistance of leather and cloth; Suitable for cement setting and molding; The refining of pharmaceuticals, glycerol and sugars can be used as a good catalyst and bonding of papermaking.
