It is a water-soluble and linear organic polymer with high molecular weight copolymerized by cation monomer and acrylamide C1250CF； C1260CF； C1270cf has high organic matter content or wastewater treatment of pharmaceutical factories such as penicillin and erythromycin C1280CF； Separation of titanium ore cracking solution C8020CF； C8030BF； C8030CF； Industrial wastewater or mixed industrial and domestic wastewater C8035BF； C8035CF； C8040BF； C8040cf municipal sewage plant sludge dewatering, digested sludge C1205CF； C8015CF； C8020CF； Papermaking wastewater treatment Cationic polyacrylamide can be used in industrial and municipal sewage treatment. Generally, products with medium or low ionic degree, medium or high molecular weight are used for the treatment of industrial wastewater or mixed industrial and domestic wastewater. Products with medium or high ionic degree, medium or high molecular weight are used for the treatment of domestic sewage, and products with high ionic degree are better for the digestion sludge. After concentration and flotation, cationic polyacrylamide can effectively remove the organic matter in wastewater.
