  • 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.
  • 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.
  • Does polymer distribution affect mechanical properties of cationic polyacrylamide dry-strength resin?
  • Mihara and Yamauchi showed the effect of polymer distribution on mechanical properties of paper sheets containing various amounts of cationic polyacrylamide dry-strength resin by DMA analysis performed in the 100–300 °C temperatures range in vibration mode at various frequencies [ 100 ].
  • What is a cationic polyacrylamide (CPAM) product?
  • A cationic polyacrylamide (CPAM) product was successfully synthesized as an aqueous dispersion with acrylamide (AM) and acryloyloxyethyltrimethyl ammonium chloride through dispersion polymerization in aqueous solution of ammonium sulfate.
