紫外光老化試驗箱是**檢測儀器，適用于通過光 水曝露加速老化試驗，預(yù)測油漆 、涂料、塑料等非金屬材料的相對耐久性，尤其適合觀察特別耐用材料的物理性能破壞，如光澤降低、霧影、強度降低、粉化、開裂、起泡、脆化和褪色等。
Ultraviolet light aging test box is a testing instrument. It is suitable for accelerated aging test by light and water exposure. It predicts the relative durability of non-metallic materials such as paint, coatings and plastics. , Haze, reduced strength, chalking, cracking, blistering, embrittlement and fading.
紫外光老化試驗箱采用的旋轉(zhuǎn)樣板架設(shè)計可以很好地補償由于燈管老化和各批次差異等諸多因素帶來的光輻射不均勻缺陷，省卻了一般儀器需定期按順序互換樣板位置的繁重工作量。
由于水分是加速老化的重要破壞因素，本裝置采用水噴淋方式模擬濕氣的影響。通過對噴淋時間的設(shè)定，可以比較接近某些A終使用的環(huán)境條件，如溫度劇變或雨水沖刷所造成的機械侵蝕等。
同其它實驗室加速試驗一樣，不能利用本裝置的試驗結(jié)果替代天然曝曬來判定材料的實際耐久年限，但本裝置提供的對比試驗條件，對快速評估材料的抗老化性能、篩選或改進新老配方、監(jiān)控產(chǎn)品質(zhì)量是相對實用的。由于紫外光是造成戶外產(chǎn)品耐用度下降的主要光照因素，加上熒光燈管相對穩(wěn)定的光譜能量分布和低廉的價格，紫外光老化試驗箱以快捷、便利和經(jīng)濟的優(yōu)勢成為世界上目前使用A為廣泛的耐候測試機種。本裝置作為簡易機型，特別適合經(jīng)濟條件有限的實驗室選用。
The design of the rotating sample frame used in the UV aging test chamber can well compensate for the defects of uneven light radiation caused by many factors such as lamp aging and differences between batches, eliminating the need for regular instruments to regularly switch the position of the template in order. Heavy workload.
Since moisture is an important destructive factor for accelerated aging, this device uses water spraying to simulate the effects of moisture. By setting the spray time, it can be relatively close to the environmental conditions of some end use, such as sudden temperature changes or mechanical erosion caused by rain.
As with other accelerated laboratory tests, the test results of this device cannot be used instead of natural exposure to determine the actual durability of the material. Monitoring product quality is relatively practical. Because UV light is the main illumination factor that causes the durability of outdoor products to decrease, coupled with the relatively stable spectral energy distribution of fluorescent tubes and low prices, UV light aging test boxes have become the world's current use of A wide range of weathering test models. As a simple model, this device is especially suitable for laboratories with limited economic conditions.
