复配添加剂对水煤浆性能的影响

The effects of combined additives on the features of coal water slurry

选用三种商用分散剂与造纸黑液磺化、缩合处理液 ,通过复配使用研究了表面张力的变化以及对水煤浆性能的影响 ,实验结果表明 ,添加剂之间的匹配直接影响水煤浆的性能 。

Three dispersants and the additive prepared from black liquor were combined together to study the changes of interfacial tension and the slurry ability of coal water. Through the determination of interfacial tension of the combined additives solution which are at different concentration and the performance of coal water slurry, it is found that the combined additives can obviously improve the slurry ability of coal water slurry, especially in static stability.
