Anionic polyacrylamide has been known for its high viscosity and molecular weight, superior to cationic polyacrylamide. Polyacrylamide is known to have a high viscosity, so its flocculation effect will be very good. Do you know what conditions affect its viscosity?
Anionic polyacrylamide has high viscosity. When the number of electrons in the outer layer of the molecule is greater than that in the inner layer, it becomes negatively charged and the negatively charged polyacrylamide becomes unstable. Anionic polyacrylamide will be because of too many external electrons and adsorption around cationic molecules, its viscosity will also be zeng large with molecular weight. Anionic polyacrylamide is viscous in aqueous solution. In general, the higher the molecular weight, the higher the viscosity. Since anionic polyacrylamide macromolecules are long and thin chains, the resistance to movement in solution is great. Its essence is to reflect the friction force in solution, also known as the coefficient of internal friction. The solution viscosity of various organic compounds in polymer flocculant is higher and increases with the increase of molecular weight.
As mentioned above, we should have a general understanding of the conditions that affect the viscosity of anionic polyacrylamide. Viscosity plays a big role in water treatment, so we need to have a thorough understanding of it, which will be very convenient for future work.
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
