  2. 准备样品:用千分之一的天平称量样品,称量样品的量(m)由松装密度来定,详见下表。
  3. 松装密度(g/cm3) 量筒容积(cm3)

  4. 将称量好的粉末装入清理干净的量筒内,应注意尽量使粉末表面处于水平状态,然后将量筒固定在座上拧紧。具体操作步聚如下图所示:

  7.  

    计算振实密度:同一个样品连续测试三次,分别计算出每次的振实密度ρ1、ρ2和ρ3,将三次测试结果进行平均得到改样品的振实密度结果。单次振实密度的计算方法如下:
    ρ1= m/V1
    ρ2= m/V2
    ρ3= m/V3
       其中,ρi:振实密度,单位为g/cm3 

               m:YANGPINZHILIANG,DANWEIWEIg  

              Vi:振实体积,单位为 cm3(ml)


       最终振实密度ρ的计算方法如下:

    三肖选一肖一码                           ρ= (ρ1+ρ2+ρ3)/3
