Q8/UV紫外光加速老化試驗(yàn)機(jī)主要用于模擬對(duì)陽(yáng)光、潮濕和溫度對(duì)材料的破壞作用；材料老化包括褪色、失光、強(qiáng)度降低、開(kāi)裂、剝落、粉化和氧化等。紫外光老化試驗(yàn)箱通過(guò)模擬陽(yáng)光、冷凝、模仿自然潮濕，試樣在模擬的環(huán)境中試驗(yàn)幾天或幾周的時(shí)間，可再現(xiàn)戶外可能幾個(gè)月或幾年發(fā)生的損壞。
Q8/UV紫外光加速老化試驗(yàn)機(jī)中，紫外燈的熒光紫外等可以再現(xiàn)陽(yáng)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(gè)的測(cè)試循環(huán)中，溫度都是可控的。典型的測(cè)試循環(huán)通常是高溫下的紫外光照射和相對(duì)濕度在100％的黑暗潮濕冷凝周期；典型應(yīng)用在油漆涂料、汽車工業(yè)、塑膠制品、木制品、膠水等。 |

模擬陽(yáng)光
陽(yáng)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(lái)模擬陽(yáng)光中的短波紫外部分，它產(chǎn)生很少的可見(jiàn)光或紅外光譜能量。我們可以根據(jù)不同的測(cè)試要求選擇不同波長(zhǎng)的UV紫外燈，因?yàn)槊糠N燈在總的紫外線輻照能量和波長(zhǎng)都不一樣。通常，UV燈管可分為UVA和UVB兩種。
Q8/UV燈管
UVA-340燈管：UVA-340 燈管可極好地模擬太陽(yáng)光中的短波紫外光，即從365 納米到太陽(yáng)光截止點(diǎn) 295 納米的波長(zhǎng)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(yáng)紫外線強(qiáng)烈，從而可以*大程度的加速材料老化。然而，該燈管可能會(huì)對(duì)某些材料造成不符合實(shí)際的破壞。UVB-313 燈管主要用于質(zhì)量控制和研究開(kāi)發(fā)，或?qū)δ秃蛐詷O強(qiáng)的材料運(yùn)行測(cè)試。www.hongzhangroup.com
UVA-351燈管：模擬透過(guò)窗玻璃的陽(yáng)光紫外光，它對(duì)于測(cè)試室內(nèi)材料的老化*為有效。
潮濕冷凝環(huán)境
在很多戶外環(huán)境中，材料每天的潮濕時(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*多的是冷凝方法，它是模擬戶外潮濕侵蝕的*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)。
溫度控制
在每個(gè)循環(huán)中，溫度都可控制在一個(gè)設(shè)定值。同時(shí)黑板溫度計(jì)可以監(jiān)控溫度。溫度的提高可以加速老化的進(jìn)程，同時(shí)，溫度的控制對(duì)于測(cè)試的可再現(xiàn)性也是很重要的。
水噴淋系統(tǒng)
對(duì)于某些應(yīng)用而言，水噴淋能更好地模擬*終使用的環(huán)境條件。水噴淋在模擬由于溫度劇變和由于雨水沖刷所造成的熱沖擊或機(jī)械侵蝕是非常有效的。在某些實(shí)際應(yīng)用條件下，例如陽(yáng)光下，聚集的熱量由于突降的陣雨而迅速消散時(shí)，材料的溫度就會(huì)發(fā)生急劇變化，產(chǎn)生熱沖擊，這種熱沖擊對(duì)于許多材料而言是一種考驗(yàn)。Q8/UV的水噴淋可以模擬熱沖擊和/或應(yīng)力腐蝕。
噴淋系統(tǒng)有12個(gè)噴嘴，在測(cè)試室的每一邊各有6個(gè)；噴淋系統(tǒng)可運(yùn)行幾分鐘然后關(guān)閉。這短時(shí)間的噴水可快速冷卻樣品，營(yíng)造熱沖擊的條件。
照射強(qiáng)度控制：可選
選配照射強(qiáng)度控制選件可得到**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**控制照射強(qiáng)度；同時(shí)也可以延長(zhǎng)熒光燈的使用壽命
