Q8 UV Accelerated Weathering Tester
 

ASTM G154测试标准   http://www.oven.cc/oven_Article_11107117.html 


       Q8/UV紫外光加速老化试验机主要用于模拟对阳光、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。紫外光加速老化试验机通过模拟阳光、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。    
        Q8/UV紫外光加速老化试验机中,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、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。www.oven.cc 通常,UV灯管可分为UVA和UVB两种。     
Q8/UV灯管      
    UVA-340灯管:UVA-340 灯管可极好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,从而可以较大程度的加速材料老化。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,或对耐候性极强的材料运行测试。
    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最为有效。   

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。Q8/UV通过独特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。试样向外的一面暴露在自然环境中具有冷却效果,导致试样内外表面具备温差,这一温差的出现导致试样在整个冷凝循环过程中,其测试面始终有冷凝生成的液态水。
    由于户外曝晒接触潮湿的时间每天可以长达十几小时,因此典型的冷凝循环一般持续几个小时。Q8/UV提供两种潮湿模拟方法。应用最多的是冷凝方法,它是模拟户外潮湿侵蚀的最好方法。所有的Q8/UV型号都可运行冷凝循环。因为有些应用条件也要求使用水喷淋以达到实际的效果,所以有些Q8/UV型号既可运行冷凝循环又可运行水喷淋循环。     
温度控制     
    在每个循环中,温度都可控制在一个设定值。同时黑板温度计可以监控温度。温度的提高可以加速老化的进程,同时,温度的控制对于测试的可再现性也是很重要的。     
水喷淋系统     
    对于某些应用而言,水喷淋能更好地模拟最终使用的环境条件。水喷淋在模拟由于温度剧变和由于雨水冲刷所造成的热冲击或机械侵蚀是非常有效的。在某些实际应用条件下,例如阳光下,聚集的热量由于突降的阵雨而迅速消散时,材料的温度就会发生急剧变化,产生热冲击,这种热冲击对于许多材料而言是一种考验。Q8/UV的水喷淋可以模拟热冲击和/或应力腐蚀。      
    喷淋系统有12个喷嘴,在测试室的每一边各有6个;喷淋系统可运行几分钟然后关闭。这短时间的喷水可快速冷却样品,营造热冲击的条件。     
照射强度控制:可选     
    选配照射强度控制选件可得到精确型和重复性好的测试结果;光强控制系统允许用户根据不同的测试要求设置不同的光照强度。通过其反馈回路装置精确控制照射强度;同时也可以延长荧光灯的使用寿命
