What is a high molecular weight polyacrylamide (PAM)?

Low molecular weight PAM can be used as a paper strengthening agent. Medium molecular weight polyacrylamide PAM is used as a retention and drainage aid. And high molecular weight polyacrylamide is used as a flocculant in the treatment of papermaking wastewater. At present, anionic PAM is most used in the paper industry.

What is cationic polyacrylamide (CPAM)?

Cationic Polyacrylamide. In general, CPAM is white powder in appearance with an ionic degree ranging from 20% to 55%. It has the characteristics of high polymer electrolyte and is suitable for the treatment of wastewater with negative charge and rich in organic matter.

What type of polyacrylamide is Apam?

Amphoteric Polyacrylamide. APAM is formed by hydrolysis and copolymerization of vinyl amide and vinyl cationic monomer acrylamide monomer. It is an irregular zwitterionic polymer with both positive and negative charges on the molecular chain. Non-ionic Polyacrylamide.

What is Pam polymer?

PAM is one of the most widely used water-soluble polymer species with a large number of pendant amide groups presenting on its molecular backbone. Amide group has a high chemical activity which can forms a series of derivatives with many kinds of compounds.

What is cationic Pam used for?

Cationic PAM is suitable for the treatment of wastewater with high organic colloid content in industries, such as dyeing, papermaking, food, construction, metallurgy, beneficiation, coal powder, oil field, aquatic product processing and fermentation industrial fields.
