Amphoteric Polyacrylamide

Product details

The amphoteric-Polyacrylamide (NPAM) is formed through hydrolysis of a copolymer with both cationic and anionic groups within its molecules. Its advantages lie in possessing the characteristics of common cationic flocculants and demonstrating superior performance. This type of flocculant can be used within a wide range of pH values, featuring higher filtration capacity and lower cake moisture content. It can also be used for extracting minerals from strong acids or recovering valuable metals from acidic catalysts. Amphoteric ion type is not a mixture of anionic or cationic types. If cationic polyacrylamide is combined with anionic polyacrylamide, a reaction will occur resulting in precipitation. Therefore, amphoteric ion products are more ideal.amphoteric- polyacrylamide is widely used in the sludge dewatering fields of urban sewage treatment plants, breweries, food factories, tanneries, paper mills, petrochemical plants, oil fields, metallurgy, chemical industries and cosmetics.

Core advantages:

1. Synergistic effect of both types of groups: simultaneously exerting cationic electro-neutralization and anionic chelation and bridging effects;

2. Strong salt resistance: less affected by high salt content, suitable for complex water quality;

3. Wide applicable pH range: performs well in acidic, neutral, and weakly alkaline water;

4. Compact flocs: the formed flocs have a relatively stable size, and the separation of sludge and water is fast;

5. Good sludge reduction effect: the sludge cake after pressing has a lower water content, making it convenient for subsequent disposal;

Application scenarios:

1.The profile control and water-blocking agent has been tested in oil fields. This new type of amphoteric ionic profile control and water-blocking agent has superior performance compared to other single-ion characteristic profile control and water-blocking agents.

2.The new water treatment agent performs much better than other single-ion existing agents in reducing surface tension under the same conditions. For achieving the requirement of reducing surface tension, it is necessary to use both anionic polyacrylamide and cationic polyacrylamide simultaneously. However, if used improperly, it will produce white precipitates and lose its effectiveness. While ACPAM has the characteristics of amphoteric ions, it can complete the cooperative synergistic effect of anions and cations, without any precipitate generation. Especially for complex water quality conditions or water properties that frequently change, using ACPAM as a treatment flocculant is more convenient and has better effects.

3.The sludge dewatering agent. Due to the increasingly complex nature of urban sewage discharge, the requirements for sludge dewatering agents in wastewater treatment are getting higher and higher. The single cationic polyacrylamide is not yet suitable for some sludge dewatering in some cases. Therefore, our company has developed ACPAM, an amphoteric ionic sludge dewatering agent, in response to this situation. After conducting dewatering tests and usage on various sludges, it has outperformed single-ion characteristic polyacrylamide. Especially for sludge from refineries and chemical plants, using amphoteric polyacrylamide for sludge dewatering has more prominent effects.

4.In the paper industry, as a paper chemical, its effect is even beyond that of single-characteristic PAM. Especially in terms of retention and filtration aids, it can increase the filtration speed of the screen and reduce the loss of fiber fillers, and has a better effect on the wet system. It also promotes and compensates for the smoothness, strength, and difference between both sides of the paper.
