超细白云石矿粉润湿接触角的测定

摘要

根据Washburn方程，采用毛细管上升法，自行设计了简单的实验装置。提出了相对润湿接触角的概念，测定了3个超细CaCO3粉体在水中的润湿接触角。%A series of simple experimental apparatus, based on the Washburn equation and by means of the capillary ascending method, has been designed in this work. The concept of relative wetting contact angle (RWCA) has been put forward and values of RWCA for three series of ultra-fine CaCO3 powder have been measured.
