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 polyacrylamide (PAM)?

Polyacrylamide (PAM), a versatile water-soluble polymer, plays a pivotal role in enhancing various processes within the paper industry. From pulp production to wastewater treatment, PAM proves to be an indispensable chemical aiding in the optimization of paper manufacturing.

Why is polyacrylamide used in water treatment?

With the increasing global water scarcity and escalating environmental pollution, efficient water treatment has become paramount. Polyacrylamide, as a versatile polymer compound, has demonstrated significant achievements in the field of water treatment. PAM is widely used as a coagulant and flocculant in wastewater treatment.

What is polyacrylamide used for?

Flocculate or coagulate solids in a liquid may be one of the largest uses for polyacrylamide which applies to wastewater treatment, and processes like paper making and screen printing. Polyacrylamide (PAM) can be supplied in a powder or liquid form, with the liquid form being subcategorized as solution and emulsion polymer.

How polyacrylamide (PAM) is used in sewage treatment?

In sewage treatment, using polyacrylamide (PAM) can increase the recycling rate of water reuse. In petroleum extraction, polyacrylamide (PAM) is mainly used in drilling mud materials and for enhancing oil recovery, widely applied in drilling, well completion, cementing, fracturing, enhanced recovery, and other oil field extraction operations.

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.
