摘要
介绍了实验室评价PVC-U异型材耐候性的两种试验方法:人工氙弧灯老化法和QUV快速紫外线老化法。虽然人工氙灯老化法评价结果更准,但硬件投入大,运行时间长。
Two laboratory experimental methods to evaluate the weather resistance of PVC- U profile materials were introduced,i, e. artificial xenon arc light aging method and QUC accelerated ultraviolet aging method. Although the evaluating results were more accurate, artificial xenon arc light aging needed big invesment of hardwares and long operation time.
