In addition, papermaking, mineral processing, coal washing, textile, metallurgy, cement enhancers, high water absorption agents, adhesives, leather retanning agents and other industries demand will also grow steadily. It is expected that the demand of cationic polyacrylamide in 2010 will exceed 40%, will drive scientific research institutions and production enterprises to develop and produce cationic polyacrylamide. It is expected that cationic polyacrylamide products will enter the golden development period in the next few years. Therefore, accelerating the settlement of particles in the suspension, accelerating the clarification of the solution and promoting filtration has a very obvious role. Anions, cations and ions. Among them, cationic polyacrylamide is an effective flocculant for sewage treatment. Therefore, it is of great significance to produce high molecular weight cationic polyacrylamide and apply it in some fields. Polyacrylamide can be divided into non-ionic type according to ionic properties. The project will produce a range of high molecular weight and molecular weight cationic and anionic polyacrylamide emulsion products. Cationic polyacrylamide main flocculation with negative charge colloid, with turbidity removal, decolorization, adsorption, adhesion, suitable for printing and dyeing, paper, food, construction, metallurgy, mineral processing, coal powder, oil fields, aquatic products processing and other industries, fermentation. It is suitable for the dewatering treatment of municipal sewage, municipal sludge, papermaking sludge and other industrial sludge.
