介绍了国内测定无机化工产品中堆积密度的几种方法,通过试验方法分析对比,说明各方法的优缺点。目前国际上公认的方法是国际标准ISO3595:1993《金属粉末振实密度的测定方法》,用振实仪器进行测定,该方法科学、准确。我国已经将该国际标准等同转化为国家标准,现已经完成标准制定工作,该标准方法达到了国际先进水平。同时也将测定松密度方法转化成国家标准,标准现已经批准发布,该标准达到国内先进水平。
The domestic methods for determining the bulk density of inorganic chemical products are introduced. The comparative analysis of the test methods and the advantages and disadvantages of each method are given. At present, internationally accepted method is the international standard ISO3595: 1993 “metal powder tap density determination method”, with vibrating instrument for determination, the method is scientific and accurate. China has transformed the international standard into a national standard, and now it has completed the standard-setting work and the standard method has reached the international advanced level. At the same time, the method of determining the bulk density is also transformed into a national standard. The standard has now been approved for release and the standard has reached the domestic advanced level.
