Is PHPA a water soluble polymer?

PHPA is a co-polymer of anionic character and high molecular weight. It is a water-soluble polymer, which is primarily used as a highly efficient fluid loss reducer, Viscosifier and protective colloid for shale’s and cutting in fresh water, calcium, sodium brines and KCL mud systems.

What is partially hydrolyzed polyacrylamide (PHPA)?

Partially hydrolyzed polyacrylamide (PHPA), consisting of neutral acrylamide and anionic acrylate groups, is suitable for use in water with <25,000 mg/L TDS 12, 15.

What is dewatered polyacrylamide emulsion?

.Dewatered emulsionsDewatered polyacrylamide emulsions differs from standard by the fact that they contain less than 6% water, with the result that the hydrogel has become almost the dry polymer itself. The consistency of the polymer is simi ar to plastic material. Most dewatered polyacrylamide emulsions from SNF ha

Can a polyacrylamide emulsion be diluted with water?

r solutionFundamentalsPolyacrylamide emulsions are not simple concentrated solutions of polymer, so a simple dilution i water is not possible. When preparing a polymer solution from an emulsion, there are two physical phenomena (phase inversion and dissolution) which take place and need specific conditi

What is hydrolyzed polyacrylamide (HPAM)?

Hydrolyzed polyacrylamide (HPAM), a derivative resulting from the hydrolysis of PAM, demonstrates significant thickening capabilities in freshwater and at relatively lower temperatures (<75 °C) due to strong intra- and inter-chain electrostatic repulsion of carboxylate groups 14.

Can modified polyacrylamide be used in drilling technology?
