摘要
介绍了PVC涂层膜材料的光氧老化机理;系统地介绍了人工加速老化试验和自然老化试验方法及参照的国内外标准,并对材料老化后的测试方法做了介绍;最后分析了PVC膜材料在人工加速老化试验和自然老化试验下的相关性的研究现状及存在的问题。
The photo-oxidation mechanisms of PVC-coated membrane material is briefly explained. Both artificial accelerated and outdoor exposure tests on PVC-coated membrane material and standards related to PVC-coated membrane material as well as some testing methods after aging are introduced systematically. Finally the research of status quo and existing problems of the correlation between results from artificial accelerated ageing and that from outdoor ageing of PVC-coated membrane material are analyzed.
