摘 要: 采用滴液法、 正向滲透法和反滲濕潤法分別研究了3種陰離子型濕潤劑對10種硫化礦粉塵的濕潤效果， 比較了不同實(shí)驗(yàn)裝置研究濕潤劑濕潤粉塵的相關(guān)性。 結(jié)果表明： 溫度約20 ℃時， 使用上述3種實(shí)驗(yàn)方法對相同的試劑和粉塵做濕潤實(shí)驗(yàn)沒有相關(guān)性， 許多情況下還出現(xiàn)完全相反的結(jié)果； 而對于相同的實(shí)驗(yàn)裝置， 3種濕潤劑都具有較好的相關(guān)性。 由此可以看出， 實(shí)驗(yàn)室研究濕潤劑所采用的方法在原理上要與應(yīng)用現(xiàn)場的特征相適應(yīng)， 否則就將適得其反。

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.
