  • What is anionic polyacrylamide (Apam)?
  • 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
  • What type of polyacrylamide is used in oil industry?
  • The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
  • 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 poly acrylamide-co-acrylic acid (Apam) used for?
  • Poly (acrylamide- co-acrylic acid) copolymers and their sodium salts (APAM) are widely used as a thickening agent, binder, superabsorbents, soil conditioner, filtering aid, a flocculating agent, cross-linker, suspending agent, lubricant, and oil recovery agent. One of its largest uses is wastewater treatment.
