Can polyacrylamide be used as paper dispersant?

Polyacrylamide could be used as paper dispersant, paper residence filter aid. The paper fibers and fillers in pulp are hydrophobic and tend to flocculate into clusters. It is difficult to produce paper with uniform properties and good strength. The addition of polyacrylamide promotes the dispersion of paper fibers and the formation of paper.

Why is polyacrylamide used in paper industry?

Polyacrylamide (PAM) in paper industry is widely used as retention agent, filter aid, homogenizer, and water treatment agent and so on. Its function is to improve the quality of paper, improve the pulp dehydration performance, improve the retention of fine fibers and fillers, and reduce the consumption of raw materials and environmental pollution.

What is anionic polyacrylamide (Apam)?

Anionic polyacrylamide (APAM) is a hydrophilic polymer which is easy to be carbonized (Choi et al., 2004). The amide group (−CONH 3) on APAM can form hydrogen bond with the uncondensed amine groups on surface of g-C 3 N 4 (Schwinghammer et al., 2014).

What is cationic polyacrylamide used for?

Polyaluminium chloride, anionic or cationic polyacrylamide are commonly used in the recovery of white water from papermaking, while cationic polyacrylamide is commonly used in air flotation treatment.
