摘要
利用自行设计的微型可视化反应器研究了液体石蜡-水、乙苯-水体系的界面性质。实验测得静置的液体石蜡-水体系的界面相厚度为9.5μm,界面与器壁的接触角为36.97°;静置与扰动过的乙苯-水体系的界面相厚度分别为45.68μm、73.27μm。为液液界面相厚度与接触角的可视化测量提供了一种新的测量方法。
Interface properties of liquid paraffin-water and ethylbenzene-water are studied with visualization micro-reactor designed by us. The interface phase thickness for liquid paraffin-water system is 9.5μm,and the contact angle between the interface and wall is 36.97°. Interface phase thickness for undisturbed and disturbed ethylbenzene-water system is 45.68μm and 73.27μm, respectively. A new method for visualization measurement of interface phase thickness and contact angle for liquid-liquid system was put forward.
