摘要：

为明确煤尘粒径对表面活性剂复配溶液润湿能力的影响,以径长范围为小于74、74 ~104、104 ~147μm的3种红柳煤样为研究对象,开展沉降试验。选取十二烷基硫酸钠(SDS)、脂肪酸甲酯乙氧基化物磺酸盐(FMES)、脂肪醇聚氧乙烯醚硫酸钠(AES)、异辛醇聚氧乙烯醚(JFC)和辛癸基葡糖苷(APG)5种表面活性剂,将其以质量比1∶1两两复配成10种复配组合,分别对单体和复配溶液作沉降试验,探究不同粒径煤尘在复配溶液和组成它们的表面活性剂单体溶液中的沉降速度变化特征。结果表明:煤尘粒径不会影响表面活性剂之间的协同润湿作用,但会影响表面活性剂之间的协同润湿程度;不同复配组合之间的润湿能力强弱不因煤尘粒径改变而变化;相较小粒径煤尘,复配溶液质量分数提高对大粒径煤尘润湿能力的提升更为明显;SDS与JFC复配组合对不同粒径煤尘均有很好的润湿效果,通过表面活性剂处理前后煤样的红外光谱分析推测,SDS与JFC能够协同提高煤尘的润湿性。

Abstract:

To study the effect of coal dust particle size on the wetting ability of surfactant compound solutions, three Hongliu coal samples with diameter length ranges of less than 74, 74-104, and 104-147 μm were used for the sedimentation test. Five surfactants, sodium dodecyl sulfate (SDS), fatty acid methyl ethoxylate sulfonate (FMES), sodium alcohol ether sulphate (AES), isooctyl ethoxylate (JFC) and octyldecyl glucoside (APG), were selected and compounded pairwisely at a mass ratio of 1∶1 to form 10 compound combinations, and the sedimentation tests were conducted on the monomer and compound solutions, respectively, to investigate the effect of different particle sizes on the wetting ability of coal dust in the compound solutions and in the compound solutions. The settling rate of coal dust in the compound solution and the surfactant monomer solution was investigated. The results show that: the particle size of coal dust does not affect the synergistic wetting effect between surfactants, but affects the degree of synergistic wetting between surfactants. The wetting ability of different combinations does not change due to the change in particle size of coal dust. The increase in the concentration of the compound solution improves the wetting ability of large particle size coal dust more obviously than that of small particle size coal dust. The combination of SDS and JFC has good wetting effect on different particle sizes of coal dust. The IR spectra of the coal samples before and after surfactant treatment showed that SDS and JFC could synergistically improve the wettability of coal dust.
