What is polyacrylamide (PAM)?

PAM, or anionic Polyacrylamide, is a very long chain, high molecular weight organic polymer produced from natural gas, with characteristics which make it useful as a soil amendment to control runoff and soil loss.

What are the different types of polyacrylamide water treatment?

Description: According to ionic characteristics, it can be divided into four types, non-ionic polyacrylamide NPAM, anionic polyacrylamide APAM, cationic polyacrylamide CPAM and amphoteric polyacrylamide. At present, the PAM water treatment is generally anionic type.

What is the standard state of polyacrylamide?

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated.

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 polyacrylamide polymer?

Polyacrylamide, also briefly referred as PAM, is commonly a polymer with acrylamide monomers bonded connected by end to end configuration; it is a hard glassy solid at room temperature. Because of the difference in production methods, the products can be white powder, translucent beads and flaky like.

What is anionic polyacrylamide used for?

Anionic polyacrylamide can be used as a cytoplasm additive in the paper industry with better retention and drainage effect. It has a particularly dispersing effect for long-fiber pulp when its molecular weight is greater than 3.5 million. In addition, it can also be used as a water treatment agent.
