摘要
详细介绍了聚苯乙烯塑料样品在中美两国四个典型自然气候曝露试验场的曝露试验情况,测量了样品曝露试验前后的黄色指数变化,并对这些数据进行了统计分析,研究了不同曝露开始时间造成的曝露季节变化对试验结果的影响,比较了这四个气候曝露试验场对聚苯乙烯的气候严酷性,结果为:海南琼海曝露试验场>佛罗里达曝露试验场>亚利桑那曝露试验场>广州花都曝露试验场。
This article gives a detailed presentation of the exposure test process of polystyrene specimens in Chinese and American natural exposure test sites. Test results include the change of Yellowness Index for every specimen after the exposure test, the effect of seasonal variation due to different start times, the statistic analysis of data, and weather severity comparison of these exposure sites for polystyrene. The weather severity ranks of these exposure sites for polystyrene were given as follows： Hainan exposure site 〉 Florida exposure site 〉 Arizona exposure site 〉 Guangzhou exposure site.
