熔體流動速率計(jì)算公式:

MFI值:即為分子量流動與剪切速率之間的關(guān)系。
  
熔體流動指數(shù)值國際通用單位是:g/10min;意思即為每10分鐘流出多少克?就是指塑膠在熔融狀態(tài)下,600秒時間擠出來的量,

熔體(質(zhì)量)流動速率儀用MFR表示,單位為:克/10分鐘(g/min)公式表示:MFR(θ、mnom )
                       =tref  .m/t
式中: θ——  試驗(yàn)溫度
          mnom—  標(biāo)稱負(fù)荷Kg
           m ——  切斷的平均質(zhì)量g
          tref ——  參比時間(10min), S ( 600s )
           t  ——  切斷的時間間隔s
     舉例:一組塑料試樣,每30秒鐘切取一段,各段質(zhì)量的結(jié)果是:0.125克、0.132克、0.138克、0.129克、0.135克取。

平均值m =(0.125+0.132+0.138+0.129+0.135)÷5=0.131(克)
代入公式:MFR=600×0.131/30=2.620(克/10分鐘)
MI值=2.620g/min
