Comparison of adsorption ability of PAM, APAM and CPAM on

Therefore, through molecular dynamics simulations, our focus in this work was mainly to compare, explain and summarize the parameters which achieve directly the adsorption mechanism of PAM (Nonionic Polyacrylamide), APAM (Anionic Polyacrylamide) and CPAM (Cationic Polyacrylamide) on sodium-MMT (Na-MMT) surface in aqueous solution, and to

Polyelectrolyte polymers¡ªTypes, forms, and function

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 [80]. Both high- and low-molecular-weight polymers are used as drilling fluid additives.

Inhibition mechanism of cationic polyacrylamide on

Since the last century, CPAM and its derivatives have been added to the water-based drilling fluids as a primary shale inhibitor to prevent the hydration of shale layers, maintain wellbore stability, and guarantee the drilling process safely. Zhong et al. [9] utilize CPAM as an additive to prepare a shale inhibitor with excellent performance.

Polyaluminium Chloride and Anionic Polyacrylamide Water

Polyaluminium chloride and anionic polyacrylamide water treatment residuals (PAC-APAM WTRs) as an amendment in three types of soils with the ratios (w/w) of 10%, 15%, and 20% were evaluated for phosphorus adsorption from aqueous solutions by batch studies. Compared with soils without PAC-APAM WTRs, the maximum adsorption capacity of phosphorus increased by 0.50 to 25.30% in silty clay soil
