UV老化測試
UV老化測試適用于非金屬材料的耐陽光和人工光源的老化試驗。試驗模擬陽光、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。紫外光老化試驗箱通過模擬陽光、冷凝、模仿自然潮濕,試樣在模擬的環境中試驗幾小時甚至幾天的時間,可再現戶外可能幾個月或幾年發生的損壞。
陽光中的紫外線是造成大多數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,它產生很少的可見光或紅外光譜能量。我們可以根據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。
在紫外光耐氣候測試中,紫外燈的熒光紫外等可以再現陽光的影響,冷凝和水噴淋系統可以再現雨水和露水的影響。在整個的測試循環中,溫度都是可控的。

UV aging test
UV aging test is applicable to the aging test of non-metallic materials against sunlight and artificial light source. The test simulates the destructive effect of sunlight, humidity and temperature on materials; Material aging includes fading, light loss, strength reduction, cracking, peeling, pulverization and oxidation. The ultraviolet light aging test chamber can reproduce the damage that may occur in months or years outdoors by simulating sunlight, condensation, and natural humidity, and by testing samples in a simulated environment for hours or even days.
The ultraviolet ray in sunlight is the main factor that causes the damage to the durability of most materials. We use ultraviolet lamps to simulate the short wave ultraviolet part of sunlight, which generates little visible or infrared spectral energy. We can choose different wavelength UV lamps according to different test requirements, because each lamp has different total UV radiation energy and wavelength.
In the ultraviolet weather resistance test, the fluorescent ultraviolet of the ultraviolet lamp can reproduce the influence of sunlight, and the condensation and water spray system can reproduce the influence of rain and dew. During the whole test cycle, the temperature is controllable.
