产物描写
广州紫外光耐天气尝试箱
      Q8/UV广州紫外光耐天气尝试箱首要用于摹拟对阳光、湿润和温度对资料的粉碎感化;资料老化包含退色、失光、强度下降、开裂、剥落、粉化和氧化等。紫外光加快老化尝试机经由历程摹拟阳光、冷凝、仿照天然湿润,试样在摹拟的情况中尝试几天或几周的时候,可再现户外能够几个月或几年发生的粉碎。     
        Q8/UV广州紫外光耐天气尝试箱中,紫外灯的荧光紫外等能够再现阳光的影响,冷凝和水喷淋体系能够再现雨水和露珠的影响。全部的测试轮回中,温度都是可控的。典范的测试轮回凡是是高温下的紫外光照耀和绝对湿度在100%的暗中湿润冷凝周期;典范利用在油漆涂料、汽车产业、塑胶成品、木成品、胶水等。 摹拟阳光      
    阳光中的紫外线是形成大大都资料经久机能粉碎的首要身分。咱们利用紫外灯来摹拟阳光中的短波紫外局部,它发生很少的可见光或红外光谱能量。咱们能够按照差别的测试请求挑选差别波长的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 凡是,UV灯管可分为UVA和UVB两种。      
Q8/UV灯管       
    UVA-340灯管:UVA-340 灯管可极好地摹拟太阳光中的短波紫外光,即从365 纳米到太阳光停止点 295 纳米的波长规模。     
    UVB-313灯管:UVB-313 灯管收回的短波紫外光比凡是照耀在地球外表的太阳紫外线激烈,从而能够*大水平的加快资料老化。但是,该灯管能够会对某些资料形成不合适现实的粉碎。UVB-313 灯管首要用于品质节制和研讨开辟,或对耐候性极强的资料运转测试。
    UVA-351灯管:摹拟透过窗玻璃的阳光紫外光,它对测试室内资料的老化*为有用。   
湿润冷凝情况      
    在良多户外情况中,资料天天的湿润时候可长达12小时。研讨标明形成这类户外湿润的首要身分是露珠,而不是雨水。Q8/UV经由历程怪异的冷凝功效来摹拟户外的湿润侵蚀。在尝试历程中的冷凝轮回中,测试室底部蓄池塘中的水被加热以发生热蒸气,并布满全部测试室,热蒸汽使测试室内的绝对湿度坚持在100%,并坚持一个绝对高温。试样被牢固在测试室的侧壁,从而试样的测试面曝露在测试室内的情况氛围中。试样向外的一面裸露在天然情况中具备冷却成果,致使试样表里外表具备温差,这一温差的呈现致使试样在全部冷凝轮回历程中,其测试面一直有冷凝天生的液态水。 
    因为户外曝晒打仗湿润的时候天天能够长达十几小时,是以典范的冷凝轮回普通延续几个小时。Q8/UV供给两种湿润摹拟体例。利用*多的是冷凝体例,它是摹拟户外湿润侵蚀的*好体例。一切的Q8/UV型号都可运转冷凝轮回。因为有些利用前提也请求利用水喷淋以到达现实的成果,以是有些Q8/UV型号既可运转冷凝轮回又可运转水喷淋轮回。     
温度节制      
    在每一个轮回中,温度都可节制在一个设定值。同时黑板温度计能够监控温度。温度的进步能够加快老化的历程,同时,温度的节制对测试的可再现性也是很首要的。     
水喷淋体系      
    对某些利用而言,水喷淋能更好地摹拟*终利用的情况前提。水喷淋在摹拟因为温度巨变和因为雨水冲洗所形成的热打击或机械侵蚀是很是有用的。在某些现实利用前提下,比方阳光下,堆积的热量因为突降的阵雨而敏捷消失时,资料的温度就会发生急巨变更,发生热打击,这类热打击对很多资料而言是一种磨练。Q8/UV的水喷淋能够摹拟热打击和/或应力侵蚀。       
    喷淋体系有12个喷嘴,在测试室的每一边各有6个;喷淋体系可运转几分钟而后封闭。这短时候的喷水可疾速冷却样品,营建热打击的前提。     
照耀强度节制:可选      
    选配照耀强度节制选件可获得**型和反复性好的测试成果;光强节制体系许可用户按照差别的测试请求设置差别的光照强度。经由历程其反应回路装配**节制照耀强度;同时也能够耽误荧光灯的利用寿命
