| 摘 要： | 选用3种不同煤化程度的煤和2种添加剂制备水煤浆，研究煤化程度对制浆性质的影响；用木质素磺酸钠（sodium-lignosulphonate,SLS）与萘磺酸钠甲醛缩合物（NSF）及其复配分散剂进行制浆试验，研究这2种分散剂对制浆性能的影响及其协同作用。通过对3种煤进行成浆试验，结果表明：对于3种不同煤化程度的煤样，SLS分散剂的成浆性能比NSF差；低变质煤样成浆性较差，且通过分散剂的复配并不能够明显提高其成浆性；高变质煤样的成浆性较好，且通过分散剂的复配能够明显提高其成浆性。 |
| 关 键 词： | 煤化学工程；复配分散剂；成浆性；煤化程度；流动性；稳定性 |

| Abstract： | In this paper, the promoter action of different dispersants on coal�s slurry ability has been studied by using 3 kinds of coals in different ranks, to study the influence of coal rank on character of coal�s slurry. The experiment uses sodium-lignosulphonate(SLS) and naphthalenesulfonic acid-formaldehyde condensate (NSF) as additives. The synergistic effects of SLS and NSF and their compound dispersants have been researched yet. The results show that: the SLS dispersant has lower slurry property than the NSF to the three coal samples with different ranks; the low-rank coal has low slurry property, which can not be obviously increased by recomposing dispersants; and the high-rank coal has high slurry proerty, which can be obviously increased by recomposing dispersants. |
