Abstract

The correlation between the diffusion permeability of thermoplastic polyurethanes by kerosene and kerosene volatility is studied. The kinetic dependences of kerosene mass loss in a diffusion cell differ from the conventional dependences that confine the application of commonly accepted parameters in estimating the diffusion permeability of polymers and the natural loss prediction model. An approach to estimating the rate of natural kerosene loss under storage is proposed. The correlation between the natural loss rate at different kerosene storage temperatures and the kerosene vapor pressure at room temperature is established to simplify the method of estimating the diffusion permeability of thermoplastic polyurethane by kerosene.

从煤油的饱和蒸气压估算热塑性聚氨酯的燃料渗透性

摘要

研究了热塑性聚氨酯对煤油的扩散渗透性与煤油挥发度之间的相关性。扩散池中煤油质量损失的动力学依赖性不同于传统的依赖性，传统的依赖性限制了在估计聚合物扩散渗透性和自然损失预测模型中普遍接受的参数的应用。提出了一种估计储存过程中天然煤油损失率的方法。建立了不同煤油储存温度下的自然损失率与室温下煤油蒸气压之间的相关性，以简化估算煤油对热塑性聚氨酯扩散渗透性的方法。
