high Molecular Weight Zwitterionic polyacrylamide (ZPAM)

Zwitterionic polyacrylamide Widely applicable High-Efficiency

 ZPAM is a novel amphoteric polymer with irregular configuration. IR analysis indicates that carboxyl group (negatively charged) and vinyl group (positively charged) coexist on the ZPAM chains, which is far better than the ability of single existence of anionic PAM and cationic PAM under the same condition.

Application:

1 polymer flocculants for water treatment

1 polymer flocculants for water treatment:

ZPAM is a novel kind of polymer flocculants for water treatment. In many cases, combined use of anionic PAM and cationic PAM can significantly provide coordinated effect and lower the surface tension, but improper use of the oppositely charged PAM may lead to white precipitates, thus rendering failure of treatment, which can be avoided by use of ZPAM. Therefore, amphoteric polymer ZPAM is an ideal choice in water treatment especially suitable for complicated or changing water samples.

2 profile control and water shut-off agent in oil drilling:

ZPAM can be used as novel profile controlling and water plugging agent in oil drilling. It has been proved through experiment in oil field that it is more effective than any other ionic PAM agent.

3 sludge dehydrating agent:

ZPAM is a more effective sludge dehydrating agent than any other ionic PAM. Dehydrating agents are facing challenge that composition of waste water has become more and more complicated. Ionic PAM has been losing effects. ZPAM that we provide has been proved to be more applicable, in dehydrating sludge from oil refinery and chemical plants.

4 retention and filtration agents used in papermaking:

ZPAM as retention and filtration agents in papermaking can increase the filtration speed and reduce the loss of fiber and can also improve the smoothness and strength and help reduce side difference of paper.
