氙灯耐气候试验箱原理及作用:氙灯耐气候试验箱采用能模拟全阳光光谱的氙弧灯来再现不同环境下存在的破坏性光波,可以为科研、产品开发和质量控制提供相应的环境模拟和加速试验。

氙灯耐气候试验箱具有光照、淋雨、湿度、凝露及军标150等六个环境因素,而且可以独立调整,采用氙灯作光源,具有与太阳光近似的光谱分布,因此以氙灯光模拟太阳光。同时温度和湿度较宽的调节范围供调节,淋雨采取独立循环系统,因此在必要时,可以在淋雨的供水源处加入有害气体物质。改变样架冷却水温,可以调整样品表面的凝露量及试样表面温度,因此,氙灯耐气候试验箱可作多因素耐气候的组合试验。

1.每个试验条件或每个暴露阶段的试样数量由暴露后的性能测试方法确定。(注:力学性能的测试,氙灯耐气候试验箱*两倍于相应测试方法所需的试样。这是因为塑料老化后的力学性能在测试时会有较大的分散性。)

2.按初始值的测试需要量和暴露阶段数来确定试样总数量。

3.如果使用的测试方法没有规定暴露试样的数量,*每个暴露阶段的每种材料至少准备三个重复试验的试样。

4.每个暴露试验应包括一个已知耐侯性的参照试样。这样有助于补偿试验与试验之间的差异,并将有助于在材料研制发展或质量控制工作中对材料的耐侯性作出评价。如果要进行实验室之间对比,事先需确定一致的参照标准。

5.气候环境对有机物物的老化,颜料褪色,金属的腐蚀有较大的影响。因此氙灯耐气候试验箱老化试验愈来愈受到橡胶、塑料、油漆、石油化工、汽车、纺织等行业的重视。气候环境因素很多,如太阳光照、温度、湿度、雨淋、凝露;有害气体,粉尘等,仅仅通过某个单一环境因素的试验来评定材料的性能是不够全面的,往往要通过多个因素的组合试验,尽可能模拟自然条件才能做出较为正确的评定。虽然室外的暴露试验具有较好的真实性,但由于不同地区,不同季节气候条件各不相同。因此试验的重要性较差,同时,随着样品材料质量的不断提高,暴露试验的周期越来越长,不能满足科研和生产不断发展的需要。
