分散剂结构对水煤浆性能的影响

Influence of dispersant structure on the performance of coal- water slurry

介绍了水煤浆和常见分散剂的特点,阐述了制备高浓度水煤浆的影响因素、分散剂同煤粒的作用机理,重点综述了分散剂结构对水煤浆性能产生的影响和规律。另外,给出了理想分散剂可能具有的结构以及合成它的一些建议。

Characteristics of coal - water slurry （CWS） and conventional dispersants for its preparation were introduced. Factors that affect the preparation of highly concentrated CWS and mechanism for action of the dispersant on the pulverized coal were described. Influence and principle of molecular structure of different dispersants on performance of the CWS were emphatically summarized. In addition, model for possible molecular structure of a perfect dispersant as well as the way for its synthesis was proposed.
