Polyacrylamide is a water-soluble linear polymer formed by free radical initiated polymerization of acrylamide (AM) monomer. It has good flocculation and can reduce the friction resistance between liquids. According to ionic characteristics, it can be divided into four types: non-ionic, anionic, cationic and amphoteric.

Polyacrylamide is a widely used high molecular polymer, which has the characteristics of thickening, resistance reduction, adhesion, flocculation and so on. Different characteristics make it used in different industries. So how is polyacrylamide produced? What is the raw material for producing polyacrylamide?

The production methods of polyacrylamide are mainly divided into copolymerization and homopolymerization. The polymerization process determines the molecular weight of the finished product and the gap between the use effect. The raw materials required by different production methods are also different. For example, the raw material of homopolymerization method is acrylamide monomer (AM), while the raw material of acrylamide monomer production is acrylonitrile. The raw materials of copolymerization method are acrylamide and acrylic acid or sodium acrylate. The copolymerization method does not need hydrolysis process, and the production cycle is short, without ammonia pollution.

Our company is a science and technology development enterprise integrating the R & D, production and sales of polyacrylamide. It mainly produces cationic, anionic and non-ionic polyacrylamide. The company has a professional analysis laboratory, which can scientifically analyze the sewage that users need to be treated, and select the appropriate drugs to achieve lower treatment cost and better treatment effect.
