Synthesis and properties of comb-like polyacrylamidedispersants for coal-water slurry
摘要
Abstract
The structure and thermal stability of the dispersing agent were characterized by infrared spectrum,gel permeation chromatography,thermal and differential thermal method.The dispersion,stable performance of different length of side chain polyamide dispersants on Shenfu coal slurry were analyzed by coal-water slurry viscometer,analysis of water rate method.The wetting properties of dispersant on coal surface and zeta potential of CWS were studied by video contact angle analyzer and zeta potential instrument.The results show that the best dispersion is PAM-1000,when the molecular weight of dispersant is 3.32×104,the concentration of CWS on Shenfu coal can reach 65%,when the optimum dosage of dispersant is 0.35%,it has best viscosity reduction,the viscosity is 417 mPa · s,after 7 days the analysis of water rates is 2.88%,better dispersion stability than naphthalene sulfonate.关键词
