摘要
本文介绍了薄板毛细渗透技术测定粉体表面接触角和粉体表面能的理论基础、实验方法及其新进展 ,与传统的透过法相比 ,该法测得的接触角数据相对准确 ,而且基于不同探针液体的接触角获得的粉体表面能的成分彼此一致。
The determination of contact angle and the surface free energy components of the small particles by thin-layer wicking technique was introduced.Compared with the measurement of the permeating height, the total surface tension and the surface tension components of the particles obtained by wicking with different probe liquid were in good agreement with each other.
