潮濕冷凝環(huán)境 紫外光加速老化試驗(yàn)機(jī),紫外線加速耐候試驗(yàn)機(jī),紫外光耐氣候試驗(yàn)箱,紫外老化測(cè)試儀
在很多戶外環(huán)境中，材料每天的潮濕時(shí)間可長(zhǎng)達(dá)12小時(shí)。研究表明造成這種戶外潮濕的主要因素是露水，而不是雨水。Q8/UV通過(guò)獨(dú)特的冷凝功能來(lái)模擬戶外的潮濕侵蝕。在試驗(yàn)過(guò)程中的冷凝循環(huán)中，測(cè)試室底部蓄水池中的水被加熱以產(chǎn)生熱蒸氣，并充滿整個(gè)測(cè)試室，熱蒸汽使測(cè)試室內(nèi)的相對(duì)濕度維持在100％，并保持一個(gè)相對(duì)高溫。試樣被固定在測(cè)試室的側(cè)壁，從而試樣的測(cè)試面曝露在測(cè)試室內(nèi)的環(huán)境空氣中。試樣向外的一面暴露在自然環(huán)境中具有冷卻效果，導(dǎo)致試樣內(nèi)外表面具備溫差，這一溫差的出現(xiàn)導(dǎo)致試樣在整個(gè)冷凝循環(huán)過(guò)程中，其測(cè)試面始終有冷凝生成的液態(tài)水。
由于戶外曝曬接觸潮濕的時(shí)間每天可以長(zhǎng)達(dá)十幾小時(shí)，因此典型的冷凝循環(huán)一般持續(xù)幾個(gè)小時(shí)。Q8/UV提供兩種潮濕模擬方法。應(yīng)用最多的是冷凝方法，它是模擬戶外潮濕侵蝕的最好方法。所有的Q8/UV型號(hào)都可運(yùn)行冷凝循環(huán)。因?yàn)橛行?yīng)用條件也要求使用水噴淋以達(dá)到實(shí)際的效果，所以有些Q8/UV型號(hào)既可運(yùn)行冷凝循環(huán)又可運(yùn)行水噴淋循環(huán)。
照射強(qiáng)度控制：可選 紫外光加速老化試驗(yàn)機(jī),紫外線加速耐候試驗(yàn)機(jī),紫外光耐氣候試驗(yàn)箱,紫外老化測(cè)試儀
選配照射強(qiáng)度控制選件可得到精確型和重復(fù)性好的測(cè)試結(jié)果；光強(qiáng)控制系統(tǒng)允許用戶根據(jù)不同的測(cè)試要求設(shè)置不同的光照強(qiáng)度。通過(guò)其反饋回路裝置精確控制照射強(qiáng)度；同時(shí)也可以延長(zhǎng)熒光燈的使用壽命
