Is polyacrylamide an anti-erosion additive?

Kay-Shoemake, Jeanine L., et al. Soil Biology and Biochemistry 30.13 (1998): 1647-1654. High molecular weight linear polyacrylamide (PAM) with anionic charge is added to agricultural soils as an anti-erosion additive.

Why is polyacrylamide added to agricultural soils as an anti-erosion additive?

High molecular weight linear polyacrylamide (PAM) with anionic charge is added to agricultural soils as an anti-erosion additive. Studies have shown that soil microorganisms are able to utilize PAM as a nitrogen source and that inorganic nitrogen pools are altered in some soils treated with PAM.

What is polyacrylamide polymer?

Polyacrylamide, also briefly referred as PAM, is commonly a polymer with acrylamide monomers bonded connected by end to end configuration; it is a hard glassy solid at room temperature. Because of the difference in production methods, the products can be white powder, translucent beads and flaky like.

What is Pam polymer?

PAM is one of the most widely used water-soluble polymer species with a large number of pendant amide groups presenting on its molecular backbone. Amide group has a high chemical activity which can forms a series of derivatives with many kinds of compounds.

Can polyacrylamide be miscible?

Polyacrylamide can also quickly miscible with non-ionic, cationic and anionic surfactants, though with certain surfactants affecting the viscosity. Viscosity: The viscosity of polyacrylamide solution has a linear correlation with its molecular weight; in addition, the higher the temperature, the lower the viscosity.

What is anionic polyacrylamide used for?

Anionic polyacrylamide can be used as a cytoplasm additive in the paper industry with better retention and drainage effect. It has a particularly dispersing effect for long-fiber pulp when its molecular weight is greater than 3.5 million. In addition, it can also be used as a water treatment agent.
