  • 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.
  • 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.
  • What is cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamide (CPAM) is a synthetic polymer, and its excellent control properties make it widely used in the pulp and paper industry (Hubbe et al. 2010, Cadotte et al. 2008, Swerin 1996.
  • When should a retention aid polymer be added to a paper machine?
  • when they are added as late as practical to the paper machine system. As shown by interaction between the retention aid polymers a nd solid surfaces in a fibrous suspension. macromolecules in a flatte r adsorbed conformation. Hubbe and Wang (2002) used through the pressure screen system of a t ypical paper machine. The latter strategy,
