Study abroad polyacrylamide Status: In other countries, the United States Exxon Research and Engineering Company DNSchulz et al, McCormick et al., And Bock, who hydrophobic association study temperature and salt polyacrylamide copolymer done a lot. McCormick and other University of Southern Mississippi American people by sodium dodecyl sulfate as a surfactant, potassium persulfate as the initiator synthesized hydrophobic side chains of different length and different monomer content of AM / N- polyacrylamide, and copolymer aqueous solution at different concentrations, different salinity, temperature, nature of shear rates tested. In the experiments, the hydrophobic chain length increases, the viscosity of the aqueous solution of polyacrylamide decline. An timber C, AM and AM / C ,. AM copolymer Baoshan District cationic polyacrylamide, polyacrylamide hydrophobic monomer feed more than 0.75 when dissolved in water is still, more than 1.0 will no longer soluble in water. When increasing the proportion of hydrophobic monomers, the apparent viscosity of the solution of concentration-dependent increase. When the concentration of the solution reaches a critical concentration, the apparent viscosity jump occurs, which is due to hydrophobic association polyacrylamide caused. When polyacrylamide hydrophobic monomer feed was 0.75 (mole fraction), AM / C Baoshan District cationic polyacrylamide. Polyacrylamide formulated at the concentration of 2mg / L solution of cationic polyacrylamide in Baoshan District o. NaCl solution 342mo / L, the apparent viscosity of polyacrylamide solutions at 25 redundant conditions is 9mPa · s, polyacrylamide Flooding in line with requirements. 1) polyacrylamide: colorless or light yellow thick gel, odorless, neutral, soluble in water, soluble in ethanol, acetone, the temperature exceeds 120 ℃, decomposition, flocculation, sedimentation, Baoshan District, cationic polyacrylamide, reinforcing and so on polyacrylamide classified polyacrylamide Description: polyacrylamide (PAM) is water-soluble polymers, insoluble in most organic solvents, has good flocculation, can reduce the frictional resistance between the liquids, by ion Characteristics of sub divided into non-ionic, anionic, cationic and amphoteric four types. Polyacrylamide Product Details: PAM water-soluble polymers, insoluble in most organic solvents, has good flocculation, can reduce the frictional resistance between the liquid, according to the ionic character of sub-divided into non-ionic, anionic, cationic and four types of gender. Baoshan District polyacrylamide polyacrylamide manufacturers _ _ export enterprises (quality businessmen) provided by the Henan water purification Material Co., Ltd. Spirit. Spirit Henan water purification Material Co., Ltd. (www.gyssjs.com) located in Gongyi City, Henan Province, North Industrial Park Yamaguchi.
