摘　　要：为了提高无烟煤的润湿性,降低粉尘带来的危害,通过实验分析探究表面活性剂对无烟煤的润湿作用。拟选用10种表面活性剂,为了系统科学地获取无烟煤润湿液的最佳组分,先采用动态接触角实验对试剂进行单体优选。随后采用改良沉降实验对优选出的表面活性剂进行复配实验,得出无烟煤最佳复配润湿液。结果表明:通过改良的沉降实验得出,各试剂单体之间拮抗或协同效果,对无烟煤润湿效果最好的复配润湿液为AEO-9+NP-10(AEO-9的质量分数为0.4%,NP-10的质量分数为0.8%,体积比1∶1)。In order to improve the wettability of anthracite and reduce the harm caused by dust,the wettability of surfactant on anthracite was studied through experimental analysis.Ten kinds of surfactants are planned to be selected.In order to systematically and scientifically obtain the best components of anthracite wettability,dynamic contact angle experiment is first used for monomer optimization of reagent.Then the modified settlement experiment was used to carry out the compound experiment of the optimized surfactant,and the best compound wettability of anthracite was obtained.The results showed that the antagonistic or synergistic effect of each reagent monomer was obtained through the improved sedimentation experiment.The best compound wettability of anthracite was AEO-9+NP-10(the mass fraction of AEO-9 was 0.4%,the mass fraction of NP-10 was 0.8%,and the volume ratio was 1∶1).
