摘要: 通过表面张力实验、接触角实验和煤尘润湿性沉降试验研究煤尘润湿性能并优选润湿剂。研究表明:合适的表面活性剂可以大大提高润湿性能,矿井水具有更好的润湿性能;初选的9种表面活性剂对比试验得出阴离子和非离子表面活性剂的润湿性能优于阳离子和两性离子表面活性剂;表面活性剂的润湿性能不一定和表面活性剂的浓度成正比,30℃时表面活性剂润湿性能更好;通过接触角和煤尘润湿性沉降试验,得出浓度0.35%的快渗T是最优润湿剂。

Abstract: In this paper, the experimental surface tension, contact angle experiments and experimental study of coal dust settling dust wettability wetting properties and preferred wetting agent. Studies have shown that: Suitable surfactants can greatly improve the wetting properties, distilled water and mine water test results mine water has better wetting properties; nine kinds of surfactants derived comparative tests primaries anionic and non-ionic surfactants the superior performance of cationic wetting agent and a zwitterion surfactant; wetting properties of the surface active agent is not necessarily proportional to the concentration of the surfactant, while the results at 30 ℃ better wetting properties of the surfactant; By wetting contact angle and dust settling tests, the final concentration of 0.35% come fast infiltration T is the optimal wetting agent.

Key words: Dust, Surfactant, Wettability, Sedimentation test, The contact angle, Surface tension
