表麵活性劑是否對斥水性土壤的潤濕性有影響？——結論、致謝！

結論
不像人工創造的穩定的驅蟲表麵或多孔 介質，拒水土壤表現出潤濕動力學，由此 最初疏水的土壤隨著時間的推移變得親水 與水接觸時。 初始潤濕動力學 排斥土壤通常歸因於 固液界麵能 (γSL)，或液汽界麵能 (γLV) 的降低，或兩者兼而有之。 γLV 的減少 建議是由於土壤表麵溶解 活性有機化合物進入與水接觸的水中 土壤。 在這項研究中，91视频网址软件測試了土傳表麵的影響 潤濕動力學的活性物質，並發現，與廣為接受的範式相反，土壤釋放表麵 活性化合物不會加速潤濕過程。 因此很明顯，固體界麵能的變化 表麵（γSL 或 γSV），而不是液汽 表麵 (γLV) 必須在驅動不穩定排斥性土壤的潤濕動力學方麵起主導作用。
