[交流] 表征水分对尼龙66机械特性的影响

66 Nylon is one of many polymers known to be hydroscopic and to have its physical properties significantly influenced by absorbed moisture. Dynamic Mechanical Analysis (DMA), which measures the modulus (stiffness) and damping properties of materials, provides a convenient method for rapidly quantifying the adverse effects of absorbed moisture.
Observations from the DMA analysis can be used to correlate with specific end-use properties of the material to permit:
        Selection of optimum in-use environment
        Prediction of mechanical stability as a function of humidity
        Correlation of impact stability with damping and humidity
        Quality control of incoming raw materials
