The blistering phenomenon is one of the major damages in bituminous pavement during a hot summer. The phenomenon was believed to be caused by water permeating from outside via channels of connected p...
温度对气调包装薄膜透气性的影响（Effects of Temperature on Gas Permeability of Films for Modified Atmosphere Packaging）
气调包装 薄膜材料 透气系数
2010/2/26
通过小袋法测定了不同材料薄膜分别在2、8、14、20℃下的薄膜透气系数，分析了温度对薄膜透气系数和透气系数比的影响。试验得出：随着温度的升高果蔬包装薄膜的透气系数增大，薄膜材料LDPE的透气系数比显著上升，但薄膜材料PVC的透气系数比在试验温度范围内呈现不同的变化趋势。薄膜透气系数与绝对温度之间满足Arrhenius方程，透气系数的自然对数值与绝对温度的倒数值之间呈显著的线性关系。 The gas...
