The essential difference between polyaluminum chloride and polyacrylamide is not a matter for customers, technicians in the operation of the goods, there will certainly be large and small problems. For example, the use of polyaluminum chloride in the process there will be a lot of you do not understand. Some customers will inquire: Polyaluminium chloride and polyacrylamide What is the difference, just use a sewage treatment can do? Speaking of water treatment materials, we all know that PAC and polyacrylamide, but who knows the essence of the difference between them in the end? What is the difference? Polyaluminum chloride and polyacrylamide are flocculants, are mainly used in the role of water purification, but with the essential difference. First, the appearance of different Poly aluminum chloride appearance of yellow, light yellow, brown. The appearance of polyacrylamide is white powder granular. Second, the process is different Poly aluminum chloride is bauxite, aluminum hydroxide, calcium, aluminum, hydrochloric acid and other raw materials, after neutralization, pyrolysis, acid, alkali, pressurized reaction and other processes And into. Mainly divided into spray-dried polyaluminum chloride, aluminum frame filter polymer and drum dry polyaluminum chloride. Polyacrylamide is made by copolymerization of acrylamide, acrylate, cationic monomer and other raw materials, relative molecular weight is relatively high, high purity, good solubility, according to the process and raw materials are divided into anionic polyacrylamide, cationic polypropylene Amide, non-ionic polyacrylamide. Third, the use (different details) Poly aluminum chloride, good stability, widely used in drinking water and paper, printing and dyeing, textile industry and domestic sewage purification. Polyacrylamide has the greater advantage over PAC and is less dilute and more versatile, capable of overcoming difficult wastewater and high concentrations of wastewater. Anionic polyacrylamide in the coal washing industry is widely used, cationic polyacrylamide is an essential sludge dewatering products, non-ionic polyacrylamide in the coating thickening industry has been widely used.
