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 benefits of polyacrylamide in printing coating based paper?

To use the polyacrylamide in the printing coating based paper as the retention agent can improve the retention of the fillers and the fine fibers, can accelerate the dehydration speed, can settle the sewage and can reduce the pollution. So, it is important for the environment protection and the economic benefit improvement.

What are the uses of polyacrylamide?

The polyacrylamide can be used to make the heat resistant and waterproof paper as the reinforced agent.

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 the tearing strength of acrylamide paper?

Add the acrylamide, the acrylic acid and the copolymer of the acrylic acid hydroxyl ethylester and the cationic cassava starch graft into the Canadian standard beating pulp of 500ML, and add Al2 (SO4)3, make the quantitative 74.2g/m2 paper product, the tearing strength is 8950g, the strength of the middle layer is 148g, the tear factor is 135.
