用熔体流动速率仪测试流变行为的数据处理

Data Processing of Rheological Behaviors Tested by Melt Indexer

推导了采用熔体流动速率仪测试流变行为的剪切速率、剪切应力和表观粘度的计算公式 ,以及砝码重量与剪切应力的关系、熔体流动速率与剪切速率的关系 。

Calculating formulae of shear rate,shear stress and apparent viscosity in rheological behaviors tested by melt indexer are deduced.Relationship between the weight and shear stress,melt flow rate and shear rate is dealt with,their reliabilities are tested.
