Synthesis of two new dispersants for coal water slurry and its performance in making slurry

Two new coal-water slurry dispersants synthesized by methyl acrylic acid(MAA),sodium allyl sulfonat(SAS),methacryloxyethyltrimethyl ammonium chloride(DMC) and styrene,are used for the preparation of coal water slurry.And the performance of the prepared coal-water slurry is analyzed.It is found that both dispersants have steady properties and can be used in harsh environment,and they can improve performances of coal water slurry to a different degrees,with satisfying effects of cutting down the visconsity and ability to enhance the static stability of coal water slurry.
