Because zwitterionic polyacrylamide contains cationic groups and anionic groups in the molecule, it has the characteristics of general cationic flocculants and exhibits more excellent performance. This type of flocculant can be used in a wide range of PH values, with higher water filtration and lower cake water content, and can also be used for strong acid leaching of ores or recovery of valuable metals from metal-containing acid catalysts.

1. Good water solubility, can be completely dissolved in cold water.
2. The floc is tight and the dosage is small.
3. The treated water has high clarity.
4. Good compatibility with inorganic coagulant.
5. The applicable PH range is large.
1. Profile control plugging agent. After the oil field test, the performance of this new zwitterionic profile control plugging agent is higher than that of other single ion characteristics profile control plugging agent.
2. A new type of water treatment agent. When treating sewage and water in many occasions, the performance of ACPAM to reduce surface tension is much greater than the ability of cations or anions to exist alone under the same conditions. If anionic polyacrylamide and cationic polyacrylamide are used, if they are used improperly, a white precipitate will be produced and the use effect will be lost. ACPAM has the characteristics of zwitterions. It can complete the synergy of anions and cations without the formation of any precipitates, especially if the water quality is more complicated or the water properties often change. Using ACPAM as a flocculant is more Convenient and better.
3. Sludge dehydrating agent, due to the increasingly complicated nature of urban sewage discharge, the requirements for sludge dehydrating agent in sewage treatment are getting higher and higher. The single cationic polyacrylamide is not suitable for dewatering some sludge. Therefore, our company has developed ACPAM, a zwitterionic sludge dewatering agent for this kind of situation. After dewatering tests and use of various sludges, it is superior to single ionic polyacrylamide. In particular, the use of zwitterionic polyacrylamide for sludge dewatering in oil refineries and chemical plants has a more prominent effect.
4. In the papermaking industry, as a papermaking chemical, its effect is more incomparable than the single-characteristic PAM, especially in retention and filtration, it can increase the water filtration speed under the net, reduce the loss of fiber filler, and affect the wet end system. It has a good effect, and promotes and compensates for the smoothness, strength and difference between the two sides.
5. Used for textile sizing agent, stable sizing performance, less sizing, low fabric breakage rate, and smooth cloth surface.
6. Used in food and tea packaging paper, other industries, food industry, cane juice clarification and phosphorus floatation extraction of syrup in the production of cane sugar and beet sugar.
In general, zwitterionic polyacrylamide is widely used in the sludge dewatering fields of urban sewage treatment plants, breweries, food plants, tanneries, paper mills, petrochemical plants, oil fields, metallurgy, chemical industry and cosmetics.
