What is nonionic polyacrylamide used for?

4. Application 1) Coal washing: nonionic polyacrylamide can be used for the centrifugal separation of the coal washing tailing, used in the sediment, and the filtration processes of the coal dust and the coal slurry. It can help to improve the recovery rate of the coal dust and the filtration rate.

What are the characteristics of nonionic polyacrylamide?

1. Characteristics of nonionic polyacrylamide Nonionic polyacrylamide is a high polymer with a high molecular weight and a low ion exponent, which has the function of flocculation, dispersal, thickening, bonding, film-forming, relating, and colloidal stability.

Can nonionic polyacrylamide be used as oilfield blocking agent?

additives, nonionic polyacrylamide can be used as the oilfield blocking agent. 8) Soil water-absorbent agent: nonionic polyacrylamide Can be used as the water-absorbent agent for soil water conservation and sand stabilization, seeding grass, and planting trees on slopes and sand dustproof.

Is polyacrylamide a water soluble polymer?

Polyacrylamide (PAM) is a water-soluble linear high-molecular polymer formed by the polymerization of acrylamide monomers initiated by free radicals. At the same time, it is also a kind of polymer water treatment flocculant.

What are the different types of polyacrylamide water treatment?

Description: According to ionic characteristics, it can be divided into four types, non–ionic polyacrylamide NPAM, anionic polyacrylamide APAM, cationic polyacrylamide CPAM and amphoteric polyacrylamide. At present, the PAM water treatment is generally anionic type.

What is a high molecular weight polyacrylamide (PAM)?

Low molecular weight PAM can be used as a paper strengthening agent. Medium molecular weight polyacrylamide PAM is used as a retention and drainage aid. And high molecular weight polyacrylamide is used as a flocculant in the treatment of papermaking wastewater. At present, anionic PAM is most used in the paper industry.
