  • What is cationic polyacrylamide (CPAM) adsorption behavior?
  • Cationic polyacrylamide (CPAM), a typical drilling fluid shale inhibitor can prevent the clay swelling and maintain the wellbore stable. Understanding the adsorption behavior of CPAM on montmorillonite (MMT) surfaces is of great significance in explaining the excellent performance of cationic inhibitors.
  • Is polyacrylamide a cationic or nonionic polymer?
  • Recently, polyacrylamide was introduced in geotechnical engineering into the process of clay treatment . Regarding the type of polymer charge, polyacrylamide can be divided into three types: nonionic (PAM), anionic (APAM), and cationic (CPAM).
  • What is organic polymer flocculant cationic polyacrylamide (CPAM)?
  • The organic polymer flocculant cationic polyacrylamide (CPAM) has the characteristics of a low additive amount, good turbidity removal and water purification effect, and high COD removal efficiency, and it has become the most commonly used polymer flocculant in the oilfield wastewater treatment process [ 11, 12, 13, 14, 15 ].
  • How does cation monomer DMC affect CPAM reactivity?
  • The content of the cation monomer DMC directly influenced the molecular weight and cationic degree of the resulting product. The molecular weight of the CPAM decreased with an increase in cationic degree, attributed to the lower reactivity of the cation monomer compared to the acrylamide monomer.
