摘 要: 采用滴液法、 正向渗透法和反渗湿润法分别研究了3种阴离子型湿润剂对10种硫化矿粉尘的湿润效果， 比较了不同实验装置研究湿润剂湿润粉尘的相关性。 结果表明： 温度约20 ℃时， 使用上述3种实验方法对相同的试剂和粉尘做湿润实验没有相关性， 许多情况下还出现完全相反的结果； 而对于相同的实验装置， 3种湿润剂都具有较好的相关性。 由此可以看出， 实验室研究湿润剂所采用的方法在原理上要与应用现场的特征相适应， 否则就将适得其反。

Abstract: By using dropping liquid, downward penetration and upward capillary seep experiments to test three anionic wetting agents to ten dust samples of sulfide ores, their relevance of wetting effects was investigated. The results show that there is no relevance in wetting effects among three devices when the solution temperature is near 20 ℃. Furthermore, completely inverse results can be achieved in wetting effects in most cases. For the same device and various wetting agents, the wetting effects are in good coincidence. Therefore, experimental principle of the applied device in laboratory should be similar to the field if an effective wetting agent is developed. Otherwise the wetting agent may have no function in field application.
