Brief introduction of Anionic polyacrylamide
Anionic polymer flocculant is mainly used for the treatment of solid minerals in the neutral suspension. It is used to improve the removal effect of the suspended solids, Skype:frank99886600 COD and phosphate in the urban and industrial wastewater treatment. In the drinking water and wastewater treatment, it is used in the surface water clarification.
General overview of the product
The product adopt the technics of adding alkali in the propenamide and then make them homopolymerization and hydrolysis, after granulation, drying and crushing, it appears as a small white powder of granular solids.

II. Cationic polyacrylamide
Brief introduction of cationic polyacrylamide
Cationic polymer flocculant is a water soluble linear polymer,and its molecular weight is between 400-1200million. It also can be dissolved in methanol and ethanol, but can not be dissolved in ketones, esters, hydrocarbons and other organic solvents. Skype:frank99886600 Cationic CPF showed electropositive in acidic or alkaline medium, thus it is effective in the treatment of coagulation and sedimentation with the suspended particles in the negatively charged sewage water. Such as the production of grain alcohol wastewater, papermaking wastewater, wastewater of urban sewage treatment plants, beer-production wastewater, wastewater of monosodium glutamate factory, sugar-production wastewater, high content of organic wastewater, beverages-production wastewater, and printing and dyeing wastewater. In addition, cationic cpf also can be used as chemicals in oilfield, such as clay anti-swelling chemicals and thickening chemicals used in oilfield acidification , as well as enhancer chemicals used in papermaking.
