Anionic Polyacrylamide Various Conditions
Nov 01, 2017

Anionic polyacrylamide has a variety of classification methods, Anionic Polyacrylamide according to the shape can be divided into colloids, dispersions, emulsions and dry powder four, according to the type of ion can be anionic, cationic, nonionic and zwitterionic anionic polyacrylamide, Anionic Polyacrylamide then different species Is there any difference in the shelf life of anionic polyacrylamide?

 First of all to remind everyone that the usual most commonly used is dry powder anionic polyacrylamide, because of its solid content is the highest, under normal circumstances, Anionic Polyacrylamide dry powder anionic polyacrylamide in a dry, cool place can be stored for more than two years, But dubbed the solution, the storage time is very limited. In general, when the solution concentration is 0.1%, Anionic Polyacrylamide the anion anionic polyacrylamide solution is not more than one week; the cationic anionic polyacrylamide solution is not more than one day, and the solution stability is also related to the concentration of the solution, 3% to 5%) of the solution storage time longer, but 3% to 5% of the solution can not be directly to the sewage treatment, Anionic Polyacrylamide dilution before use, cationic anionic polyacrylamide solution PH value of less than 5.5 when more stable, greater than 6.0 Will be due to hydrolysis and quickly failed. Water medium dispersion type anionic polyacrylamide shelf life of six months!

It is necessary to pay attention to the preservation of anionic polyacrylamide under various conditions and taboos. PAM is sensitive to iron ions, calcium ions and magnesium ions than anionic polymers. Iron ions are the catalysts that cause chemical degradation of all anionic polyacrylamide. Anionic Polyacrylamide Therefore, Transfer, storage of anionic polyacrylamide solution, to try to avoid iron ions into contact with the solution is best to use stainless steel, plastic, glass or steel coating or surface coating resin.

Polyacrylamide is used as a starch plant and alcohol plant for the loss of starch and distillate recovery. Now a lot of starch plant discharged from the waste water is very high, Anionic Polyacrylamide after the impact of the environment, waste of resources, plus PAM, so that starch precipitation, sedimentation filter press filter into a cake can be used for feed, alcohol plant a lot of distiller's grains is With this process of processing, an alcohol factory in Heilongjiang is polyacrylamide as a flocculant, Anionic Polyacrylamide the recovery of distiller's grains and achieved great economic benefits.

Polyacrylamide for the oil field profile control water shutoff agent, three oil recovery agent. Polyacrylamide is used as a papermaking agent. Anionic Polyacrylamide PAM is widely used in papermaking, and it can be used as a long fiber paper dispersant, wet and dry enhancer, retention agent, filter aid and flocculant for papermaking wastewater.
