High purity polyacrylamide is a polymer containing more than 50 percent acrylamide. First, polyacrylamide is an acrylamide molecule and monomer. Acrylamide is moderately toxic and is absorbed mainly through the skin, endangering the nervous system! The molecular weight of polyacrylamide is different, divided into Yin, Yang, non-ion and other types! In addition, polyacrylamide is non-toxic, but contains residual acrylamide monomers during polymerization. Pay attention when using!
When there is too much high purity polyacrylamide, PAM forms and dissolves. Since PAM cannot continue on its own, it can be adsorbed on the surface of the sediment to better achieve flocculation operations. Due to the flocculation of high purity polyacrylamide, dual ionic pressure will be generated in the process of treatment, which leads to the decrease of particle aggregation stability.
High purity polyacrylamide binds to particles under molecular attraction, and the dispersed anions can be replaced by polymer anion groups. The polyacrylamide molecular chains are fixed on the appearance of different particles, and each solid particle can form a polymerization bridge. The high purity polyacrylamide polymer may react with the substance in natural water and the suspended matter in water. The application of polyacrylamide in sludge dewatering should be suitable for sludge properties and dewatering machine type.
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
