The difference between high purity polyacrylamide and polyacrylamide

2023-06-02 17:07:08


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.
