紫外光老化试验箱_紫外线老化试验仪_紫外灯老化测试箱
紫外光老化试验箱主要用于模拟对紫外线辐射阳光、潮湿和温度对材料的破坏作用;材料老化包括褪色、失光、强度降低、开裂、剥落、粉化和氧化等。紫外线老化试验仪通过模拟阳光、冷凝、模仿自然潮湿,试样在模拟的环境中试验几天或几周的时间,可再现户外可能几个月或几年发生的损坏。
UV紫外灯老化测试箱中,紫外灯的荧光紫外等可以再现阳光的影响,冷凝和水喷淋系统可以再现雨水和露水的影响。整个的测试循环中,温度都是可控的。典型的测试循环通常是高温下的紫外光照射和相对湿度在100%的黑暗潮湿冷凝周期;典型应用在油漆涂料、汽车工业、塑胶制品、橡胶、木制品、胶水等。
模拟阳光
阳光中的紫外线是造成大多数材料耐久性能破坏的主要因素。我们使用紫外灯来模拟阳光中的短波紫外部分,它产生很少的可见光或红外光谱能量。我们可以根据不同的测试要求选择不同波长的UV紫外灯,因为每种灯在总的紫外线辐照能量和波长都不一样。通常,UV灯管可分为UVA和UVB两种。
紫外光老化试验箱QUV灯管:
UVA-340灯管:UVA-340 灯管可地模拟太阳光中的短波紫外光,即从365 纳米到太阳光截止点295 纳米的波长范围。
UVB-313灯管:UVB-313灯管发出的短波紫外光比通常照射在地球表面的太阳紫外线强烈,从而可以的加速材料老化。然而,该灯管可能会对某些材料造成不符合实际的破坏。UVB-313灯管主要用于质量控制和研究开发,或对耐候性的材料运行测试。
UVA-351灯管:模拟透过窗玻璃的阳光紫外光,它对于测试室内材料的老化有效。
潮湿冷凝环境
在很多户外环境中,材料每天的潮湿时间可长达12小时。研究表明造成这种户外潮湿的主要因素是露水,而不是雨水。QUV通过的冷凝功能来模拟户外的潮湿侵蚀。在试验过程中的冷凝循环中,测试室底部蓄水池中的水被加热以产生热蒸气,并充满整个测试室,热蒸汽使测试室内的相对湿度维持在100%,并保持一个相对高温。试样被固定在测试室的侧壁,从而试样的测试面曝露在测试室内的环境空气中。

试验条件:
1.试验样品固定装置于试验架上,面对荧光灯当试样未将样品架填满时,则需用黑板将样品架填满,保持试验箱内壁封闭。
2.试验温度。光照时可采用50、60、70℃三种温度,优先推荐采用60℃;冷凝阶段的温度为50℃,温度的容差均匀度为±3℃。
4.光照各冷凝的周期可选择4H光照、4H冷凝或8H光照、4H冷凝两种循环。
在次光照400~450H后,每排灯管需更换一支荧光灯,其它灯管按照灯循环和替换方式来补偿灯管老化造成的损失。这样的运行模式确保每支灯管的使用寿命在1600~1800H。
5.在更换灯管时,应擦干盛水盘和进行清洁,避免形成水垢。
