离心浸没法测量颗粒的润湿接触角

Determination of Wet Contact Angle of Particles Using Centrifugal Immersion Method

提出了一种测量固体颗粒的固-水-气三相润湿接触角的方法(离心浸没法)。该方法可以适应各种形状的固体颗粒,文中列举了测量石墨、滑石、煤等所获得的润湿接触角的实例。

The centrifugal immersion method used for the determination of solid-water-air three-phase wet contact angle of particles is presented. The method is suitable for particles of various shapes. Some examples of wet contact angle determinations for graphite、talc、coal、etc. are given.
