manufacturer polyacrylamide pam in nigeria with factory price
polyacrylamide (iupac poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as pam) is a polymer (-ch 2 chconh 2-) formed from polyacrylamide subunits. it can be synthesized as a simple linear-chain structure or cross-linked, typically using n,n’-methylenebisacrylamide.

- Can cationic polyacrylamide be used in oilfield wastewater treatment?
- Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
- Can cationic-surfactant polyacrylamide be used as a viscosifier in drilling fluid?
- Likewise, Shettigar et al. (2018) designed a cationic-surfactant polyacrylamide as viscosifier in drilling fluid, which showed the improvement of rheology and cutting effect due to the hydrophobic and electrostatic interaction between the surfactant (cetyltrimethyl ammonium bromide) and polymer.
- 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 ).
