紫外光老化試驗箱主要用于模擬對紫外線輻射陽光、潮濕和溫度對材料的破壞作用;材料老化包括褪色、失光、強度降低、開裂、剝落、粉化和氧化等。紫外線老化試驗儀通過模擬陽光、冷凝、模仿自然潮濕,試樣在模擬的環(huán)境中試驗幾天或幾周的時間,可再現(xiàn)戶外可能幾個月或幾年發(fā)生的損壞。
UV紫外燈老化測試箱中,紫外燈的熒光紫外等可以再現(xiàn)陽光的影響,冷凝和水噴淋系統(tǒng)可以再現(xiàn)雨水和露水的影響。整個的測試循環(huán)中,溫度都是可控的。典型的測試循環(huán)通常是高溫下的紫外光照射和相對濕度在100%的黑暗潮濕冷凝周期;典型應用在油漆涂料、汽車工業(yè)、塑膠制品、橡膠、木制品、膠水等。
模擬陽光
陽光中的紫外線是造成大多數(shù)材料耐久性能破壞的主要因素。我們使用紫外燈來模擬陽光中的短波紫外部分,它產(chǎn)生很少的可見光或紅外光譜能量。我們可以根據(jù)不同的測試要求選擇不同波長的UV紫外燈,因為每種燈在總的紫外線輻照能量和波長都不一樣。通常,UV燈管可分為UVA和UVB兩種。
紫外光老化試驗箱QUV燈管:
UVA-340燈管:UVA-340 燈管可地模擬太陽光中的短波紫外光,即從365 納米到太陽光截止點295 納米的波長范圍。
UVB-313燈管:UVB-313燈管發(fā)出的短波紫外光比通常照射在地球表面的太陽紫外線強烈,從而可以的加速材料老化。然而,該燈管可能會對某些材料造成不符合實際的破壞。UVB-313燈管主要用于質(zhì)量控制和研究開發(fā),或?qū)δ秃蛐缘牟牧线\行測試。
UVA-351燈管:模擬透過窗玻璃的陽光紫外光,它對于測試室內(nèi)材料的老化有效。
潮濕冷凝環(huán)境
在很多戶外環(huán)境中,材料每天的潮濕時間可長達12小時。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。QUV通過的冷凝功能來模擬戶外的潮濕侵蝕。在試驗過程中的冷凝循環(huán)中,測試室底部蓄水池中的水被加熱以產(chǎn)生熱蒸氣,并充滿整個測試室,熱蒸汽使測試室內(nèi)的相對濕度維持在100%,并保持一個相對高溫。試樣被固定在測試室的側(cè)壁,從而試樣的測試面曝露在測試室內(nèi)的環(huán)境空氣中。

試驗條件:
1.試驗樣品固定裝置于試驗架上,面對熒光燈當試樣未將樣品架填滿時,則需用黑板將樣品架填滿,保持試驗箱內(nèi)壁封閉。
2.試驗溫度。光照時可采用50、60、70℃三種溫度,優(yōu)先推薦采用60℃;冷凝階段的溫度為50℃,溫度的容差均勻度為±3℃。
4.光照各冷凝的周期可選擇4H光照、4H冷凝或8H光照、4H冷凝兩種循環(huán)。
在次光照400~450H后,每排燈管需更換一支熒光燈,其它燈管按照燈循環(huán)和替換方式來補償燈管老化造成的損失。這樣的運行模式確保每支燈管的使用壽命在1600~1800H。
5.在更換燈管時,應擦干盛水盤和進行清潔,避免形成水垢。
