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 Pam used in papermaking?

In papermaking, PAM is employed as a retention and drainage aid. It enhances the retention of fine particles during the papermaking process, leading to improved paper quality. The improved drainage properties result in better water removal, accelerating the drying process and increasing overall production efficiency.

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.

How does polyacrylamide (PAM) reduce drag?

Polyacrylamide (PAM) can effectively reduce the frictional resistance of fluids, and adding a small amount of polyacrylamide (PAM) to water can reduce drag by 50-80%. Polyacrylamide (PAM) has thickening effects under both neutral and acidic conditions, and when the pH value is above 10, polyacrylamide (PAM) is easily hydrolyzed.

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.
