Can cationic polyacrylamide emulsions with ultra-high concentration save transportation costs?

Cationic polyacrylamide emulsions with ultra-high concentration (CPAME-uhc) can obviously save transportation costs, but their molecular weight, solubility, and temperature/salt resistance need to be further improved. Therefore, this study attempted to improve the molecular weight of CPAME-uhc by optimizing the preparation conditions.

Is cationic polyacrylamide emulsion a flocculant for paper mill wastewater treatment?

" Cationic polyacrylamide emulsion with ultra-high concentration as a flocculant for paper mill wastewater treatment ," BioRes. 15 (2), 3173-3189. Cationic polyacrylamide emulsions prepared with ultra-high concentration (CPAME-uhc) have the advantages of fast dissolution, convenient operation, and low transportation cost.

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 the chemical structure of cationic polymer emulsion?

The cationic polymer emulsion with a concentration of 60% was precipitated by a mixture of ethanol and acetone with a mass ratio of 1:1. After drying, the chemical structure of the polymer emulsion was characterized by FT-IR, as shown in Fig. 11.

Which emulsion is used to test interfacial tension of polyacrylamide?

An emulsion of the polyacrylamide (termed RSE) with ester compounds as the continuous phase was obtained. An SDT-500C spinning drop tensiometer was used to test the isoamyl caprylate–water interfacial tension using 0.5% solution prepared with emulsifiers with different hydrophilic–lipophilic balance (HLB) values.
