Abstract

The solubility and diffusion (desorption) coefficients of gaseous formaldehyde in 14 materials have been measured at different temperatures. Cellulose, paper, polyamide (Nylon 6), polyester and natural rubber (latex) show very high values of formaldehyde solubility and very low diffusion coefficients, with a weak or inversed influence of the temperature, leading to the conclusion that a chemical reaction occurs with the formaldehyde. The behaviour of the other polymers follows the classical laws of solubility and diffusion of gases except for silicone rubber which shows two-phase desorption curves.

摘要

已在不同温度下测量了气态甲醛在14种材料中的溶解度和扩散（解吸）系数。纤维素、纸张、聚酰胺（尼龙6）、聚酯和天然橡胶（乳胶）显示出非常高的甲醛溶解度值和非常低的扩散系数，温度影响微弱或呈反向影响，由此得出结论，甲醛发生了化学反应。除了硅橡胶呈现两相解吸曲线外，其他聚合物的行为遵循气体溶解度和扩散的经典规律。
