Introduction of Humidity Resistance Test Standards of Coatings
-
摘要: 介绍了现行国标、ISO标准、ASTM标准中涂层耐湿性主要测试方法,对各标准中测试方法进行了归纳总结。湿热、箱内冷凝、喷水雾均为高温高湿环境,形成冷凝水的推动力较小;单侧冷凝温差较大,引起涂层破坏的推动力较大,在同样试验温度下,冷凝更易发生。在需要快速获得涂层耐湿性试验结果时,尤其是涂层耐冷凝性能时,可以优先选用单侧冷凝试验方法。Abstract: Humidity resistance test methods in GB standards, ISO standards and ASTM standards were introduced, and the test methods were summarized. Heat and humidity, condensation(in-cabinet exposure) and water fog were all in test atmosphere of high temperature and humidity, whose impetus for condensation was relatively smaller. While the temperature difference was large with the condensation(single-sided exposure), and the impetus for coating damage was large, so with the same test temperature, condensation was easier to happen. The condensation(single-sided exposure) was a preferred option when the humidity resistance result of coating, especially resistance performance to condensation, was urgently needed.
