在恒温恒湿条件下，湿杯法检测涂料游离涂膜的透汽性，从而建立了一种简捷实用的水蒸气透过率检测方法。
Under the condition of constant temperature and constant humidity, the water vapor penetration rate of the separate coatings film is tested by the wet cup method that is simple and practical.
这种膜对水蒸气有很高的透过性，因而也可用于有机蒸气的脱水，或空气干燥。
The polyimide membrane has high H_2O vapor permeability and can be applied to dehydration of organic vapors, or air drying.
