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 are the advantages of polyacrylamide as a paper dispersing agent?

When the production speed 800m/min, the concentration 0.6%, the paper ash content 20%, the introduction of the PAM retention agent can reach 80% first processing retention and 50% first pass ash retention. When the polyacrylamide is used as the paper dispersing agent, it can improve the sheet formation.

What is the retention rate of cationic polyacrylamide?

To use the cationic PAM as the retention agent, the retention rate is 98%. The tiny fiber and the lignin in the pulp has better combination with the cationic polyacrylanmide than the anionic polyacrylamide, the cationic polyacrylamide has strong effect on the retention efforts.

What are the advantages of cationic polyacrylamide?

The tiny fiber and the lignin in the pulp has better combination with the cationic polyacrylanmide than the anionic polyacrylamide, the cationic polyacrylamide has strong effect on the retention efforts. Modify the PAM with the resin gum, the gelatin and the titanium dioxide, it could be used as the wet end additives.

What is polyacrylamide used for?

Polyacrylamide (PAM) is a collective term for polymers obtained by the homopolymerization or copolymerization of acrylamide monomers under the action of an initiator. It can be used as a coagulant, retention aid, sludge dewatering agent, and flocculant sedimentation agent, among other uses, and has a wide range of applications.

How does polyacrylamide (PAM) work?

Polyacrylamide (PAM) can cause suspended substances to flocculate through electric neutralization and bridging adsorption. It can act as an adhesive through mechanical, physical, and chemical means.
