What are the reasons for the poor use of anionic polyacrylamide

Anionic polyacrylamide (APAM) is a white powder with a molecular weight ranging from 6 million to 25 million. It has good water solubility and can be dissolved in water in any proportion and insoluble in organic solvents. The effective pH range is from 7 to 14. It has the characteristics of high polymer electrolyte in neutral alkaline medium, is sensitive to salt electrolyte, and can be cross-linked with high-valent metal ions to form an insoluble gel. What factors will affect the sewage treatment effect of anionic polyacrylamide? Through the above analysis and solution, it is proved that the viscosity of anionic polyacrylamide will be affected by pH. In order to avoid any impact on the use effect, it is recommended Customers who use Anionic polyacrylamide must pay attention during use, and Chimelong is willing to give you more awareness of related technologies. Non-ionic PAM is easily hydrolyzed. In aqueous solution, when the pH value changes from acidic to alkaline, the non-ionic amide group turns into an anionic amide group. The antelope gene has a negative charge to generate repulsion, causing the macromolecular chain to be fully stretched, so the viscosity is increased. When the degree of hydrolysis increases, the viscosity of PAM anionic polyacrylamide solution increases. When the pH value is too low, the acidity is too strong, which is easy to cause explosion polymerization, forming a cross-linked insoluble matter, and the molecular weight of the gained anionic polyacrylamide is also low: with the increase of the DH value, the acidity of the reaction solution gradually weakens and the alkalinity gradually increases , the molecular weight of the obtained Anionic polyacrylamide gradually decreases, and the solubility becomes better.
