层压是保护和保存材料免受破坏或变质的有效方法。本文介绍了一种测定层压袋膜与纸张粘合质量的方法。在这种方法中，用闪光灯快速加热粘合在纸上的层压板膜表面，然后用热像仪观察表面温度的动态变化。该方法利用了层压板与纸张粘合不良导致的动态热传递差异。我们对模拟不良结合的试件进行了验证实验，发现与良好结合的区域相比，不良结合区域的温度更低。在这里，我们概述了检测粘结不良的理论基础，并描述了以温度高于周围材料为特征的不同类型的粘结不良。最后，讨论了观测方法的应用和局限性。
Lamination is an effective way to protect and preserve materials from destruction or deterioration. In this paper, a method for determining the quality of bonding between a laminate pouch film and paper is described. In this method, rapid heating of the surface of the laminate film bonded to paper by a light flash was followed by thermographic observation of the dynamic changes in surface temperature. The method exploits the differences in dynamic heat transport caused by poor bonding between the laminate and the paper. We carried out verification experiments on test pieces constructed to simulate poor bonding and found that the temperatures in regions of poor bonding were lower compared to regions of good bonding. Here, we outline the theoretical basis of the detection of the poor bonding, and also describe different types of insufficient bonding characterized by a temperature higher than the surrounding material. Finally, we discuss the applications and limitations of the observation method.
