摘要
在分析研磨法制备煤样测定煤水接触角优缺点的基础上,采用压制煤样试片制备方法,压制了两组具有光滑表面的煤样试片。利用FTA-200新型动态接触角分析仪分别在两组煤样试片表面测定了其接触角,并对测定结果的标准差数值分析,结果表明:在压制煤样试片上测得的接触角比较准确,工作量小,可重复性好。
In the analysis of coal samples prepared by grinding the contact angle measured on the basis of advantages and disadvantages of using compressed coal sample specimen preparation methods, suppression of the two coal samples with smooth surface specimens. Using FTA - 200 contact angle analyzer with new-type dynamic to measure the surface contact angle of two coal samples respectively, and analyze the standard deviation of determination. The results showed that： the contact angle is accurate, small workload and reproducible in the suppression of coal specimen.
