  • 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 [ , , ].
  • 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).
  • Can polyacrylamide be used for drilling?
  • However, polyacrylamide with high molecular weight can be a good candidate at lower concentrations to meet the drilling requirements. The viscosity of polyacrylamide at all concentrations decreases with increasing temperature, according to Magzoub et al. (2021).
  • What is modified polyacrylamide drilling fluid?
  • Indeed, modified polyacrylamide drilling fluid has been proven to be of great interest for use in the construction of bored piles and diaphragm walls in recent years. 1. Introduction Drilling fluid is a critical component in exploration and excavation, classified into water-based, oil-based, synthetic-based, and gas-based.
