People who have knowledge of polyacrylamide know that it is mainly used for sewage treatment and has significant effects in preventing secondary pollution. So what should be noted during the use of polyacrylamide?

Polyacrylamide is a linear polymer mainly divided into two forms: dry powder and colloid. According to their average molecular weight, they can be divided into three categories: low, medium, and high molecular weight. According to its structure, it can be further divided into non-ionic, anionic, and cationic types.

In the papermaking industry, as a papermaking chemical, its effectiveness cannot be compared to a single characteristic of PAM, especially in terms of retention and filtration, it can improve the speed of offline filtration and reduce the loss of fiber fillers. It has a promoting and compensating effect on the smoothness and strength of the finished paper.

Mainly used for municipal sludge dewatering and activated sludge treatment: generally using medium to high electricity, medium molecular weight cationic acrylamide.

Polyacrylamide is a linear polymer with the chemical formula (C3H5NO) n. At room temperature, it is a hard glassy solid, and its products include glue, latex, white powder, semi transparent beads, and thin films.
