【Abstract】 The Paper introduces the synthesis method of Nephthalenesulfonate-formaldehyde condensate for a coal-water mixture (CWM). Three kinds of surfactants were examined for the ability to highly concentrate a CWM in Xinglongzhuang Coal Mine. As a result, it is found that they all contributed greatly to improving the fluidity and coal concentration of CWM, and surfactant mixtures are superior to the individual surfactant in high concentrating ability.更多还原
