防湿包装材料透湿过程数学模型探讨

Approaches to the Mathematical Model during the Water Vapor Transmission of Moistureproof Packaging

在特定的条件下,通过数理分析对于均质薄壁防湿包装材料论证了其透湿方程,并参照透湿度的实验方法建立了其在实验过程中的透湿数学模型。作为静态干燥封存包装湿热环境试验的一个具有代表性的状况及过程,该数学模型可为静态干燥封存包装计算机辅助设计提供一项防湿参数设计的分析计算依据。

This paper proves the water vapor transmission equation of homogenized thinwalled moisture-proof materials for packaging through mathematical analysis underspecific conditions and sets up the mathematical model from water vapor transmissionbased on the experiment. This model has laid an analytical and calculating basisfor moisture-proof parameter design in the CAD for the preservative packagingunder static drying conditions.
