摘要
阐述了用蜡浸法处理样品,以蒸馏水为测试介质,采用比重瓶法测试固体颗粒密度。对(直径)3—7mm 的不同形状的颗粒样品,其测定结果与汞容量法基本一致。是一种成本低廉、操作简便、精度较高、无汞、无毒的颗粒密度测试方法。
This paper describes a method for determining apparent density of porous gr-anules by pycnometer using wax in place of mercury.For 3—7mm granules withvarious shapes,the results obtained by the method agree with those obtained bymercury volumetric method.The method is a more convenient one with low cost,high accuracy and without mercury hazard.
