松香基水煤浆分散剂的合成、应用及其吸附性能
Synthesis, application and adsorption property of a dispersing agent based on rosin for coal water mixture
摘要
Abstract
A rosin derivant dispersant,maleopimaric acid taurine amide (MTA) was prepared with rosin,maleic anhydride and taurine as raw materials,and employed as the dispersing agent of the coal water mixture (CWM) fabricated from Shenfu coal.The CWM application property examination shows that the MTA has better capacity in diminishing CWM viscosity and making the slurry steady than the naphthalene sulfonate formaldehyde condensate dispersant (NSF,a commercial dispersant).The physicochemical performance detection of the two dispersants reveals that the adsorption behaviors of the both dispersants on coal surface obey the Langmuir mode.The adsorption quantity of the MTA at coal-water interface is higher than that of NSF,and the synthetic dispersant has stronger wetting and charging capability of coal surface than NSF.It suggests that the superior application performances of MTA could be related to its adsorption mode of standing upright on coal.关键词
