Nonionic polyacrylamide is a linear polymer with the chemical formula (C3H5no) n that has a variety of functions such as thickening, flocculation, sedimentation, filtration, thickening, retention and purification. It can also extend many important downstream products, widely used in oil, paper, water treatment, textile and many other industries.
Nonionic polyacrylamide is the general term for linear water-soluble polymer chemicals that are homogeneous or copolymerized with other monomers with mass fraction greater than 50%. Its special physical and chemical properties come from its molecular structure. Because the structural units contain amide groups, easy to form hydrogen bonds, so it has good water solubility. It can be easily grafted or crosslinked to obtain a variety of branched or reticulated modified products.
Preparation method and influencing factors of non-ionic polyacrylamide:
Steps: The obtained acrylamide aqueous solution is heated and purified, vacuum flash, resin is added to deionize, nitrogen is filled to deoxygenate, and pure acrylamide aqueous solution is extracted. Adding water and initiator to the obtained pure acrylamide solution, the polymerization reaction was carried out under the irradiation of halogen lamp. The irradiation temperature was 75 ~ 79℃, the reaction time was 3.8 ~ 4.2 hours, and the non-ionic polyacrylamide was generated. The obtained polyacrylamide was coarse-granulated and fine-granulated to obtain polyacrylamide granules. The obtained non-ionic polyacrylamide particles are dried, screened, ground and packed into storage.
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
