Effect of Anionic Polyacrylamide on the Structural
However, the effect of flocculants on the structural stability of thickened tailings slurries in pipeline transportation still needs further exploration. Anionic polyacrylamide (APAM) is a widely used organic polymer flocculent in tailings thickening and shows good performance and high efficiency at low cost, particularly in the treatment of
In the present study, particular emphasis was put on the effects of the type of functional groups of anionic and cationic polyacrylamide (PAM) and solution pH on the mechanism of polymer adsorption on the surface of dispersed alumina. The polymer-adsorbed amount, surface charge density and zeta potential of solid particles without and with PAM, as well as the stability of Al2O3 suspension

- 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 .
- Which comonomer is used for the production of anionic polyacrylamides?
- The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid. These anionic polymers can be prepared as various mono- and divalent metal salts and other positively charged inorganic and organic counterions of the polymerization of acrylic acid with acrylamide (see Fig. 34.4 ).
- What is a polyacrylate comonomer?
- Polyacrylates Polyacrylates are a class of anionically charged polyelectrolytes where acrylic acid and its salts are the primary monomer used in their preparation. Other comonomers can be and are incorporated into the polymer chain to alter the molecular weight and physical properties and performance of the resulting polymers.
- Is polyacrylamide a coagulant or a dispersant?
- This is very much system-dependent. Most solution polyacrylamides fall into the category of coagulants, dispersants, fixatives, and paper strength resins due to the limits of the chemistry, desired active polymer content, desired charge, molecular weights, and shelf-life.
