Product Description: zwitterionic polyacrylamide is formed by ternary copolymerization of cationic monomer, acrylamide monomer and hydrolytic agent. The molecular chain of the product contains amphoteric ions with both positive and negative charges Regular polymer. The appearance of the product is white fine particles or powdery solid. Application: it can be used as sludge dehydrating agent, especially for water with complex or frequent changes in water quality and sludge dewatering in oil refineries and chemical plants, with better effect. This product is used as water treatment floc The ability of coagulant to reduce surface tension is much greater than that of cation and anion alone under the same conditions. Zwitterionic polyacrylamide is formed by hydrolysis copolymerization because the molecule contains cationic and anionic groups. The advantage is that it has the use characteristics of general cationic flocculant. It is used for extracting ore with strong acid or recovering valuable metal from acid catalyst containing metal. Zwitterionic type is by no means a mixture of anionic type and cationic type. If cationic polyacrylamide is used with anionic polyacrylamide, it will react and precipitate. Therefore, zwitterionic products are the most ideal. Zwitterionic polyacrylamide has the characteristics of general cationic flocculant because its molecules contain cationic and anionic groups. The combination of cationic polyacrylamide and anionic polyacrylamide will react and precipitate. Therefore, zwitterionic products are the most ideal.
