PE熔体质量流动速率测量不确定度评定

Evaluation of Uncertainty in Measurement of PE Melt Mass Flow Rate

采用熔体流动速率仪对PE100混配料的熔体质量流动速率(MFR)进行测试,并对测量过程中的不确定度,如重复测量、温度、负荷等进行分析与计算。

The melt flow rate meter was used to test the melt mass flow rate(MFR)of polyethylene(PE),and the uncertainty in the measurement process,such as repeated measurement,temperature,load,etc.,was analysed and calculated.
