针对卡明斯基仪测定毛细高度方法在应用中的一些问题,该文利用卡明斯基毛细仪原理,进行了测定毛细上升高度的试验,确定渗透速度与毛细高度的关系,对比不同粒径毛细高度达到稳定时的渗透速度。结果表明,随着渗透速度的减小,毛细高度减小,减小到一定数值时,毛细高度趋于稳定;不同粒径毛细高度达到稳定时的渗透速度也不同。
Aiming at some problems in the application of the method of measuring the capillary height by the Kaminsky instrument, this paper uses the principle of Cumminski capillary instrument to test the height of the capillary, and determines the relationship between the penetration velocity and the capillary height. The capillary height reaches the steady state penetration rate. The results show that the capillary height decreases with the decrease of the penetration velocity, and the capillary height tends to be stable when the capillary height decreases to a certain value. The penetration velocities of the different particle sizes with the capillary height stable are also different.
