紫外老化试验机并不是模拟全光谱太阳光,但是却模拟太阳光的破坏作用。通过把荧光灯管的主要辐射控制在太阳光谱的紫外波段来实现。实验设备采用紫外线荧光灯模拟阳光,同时开可以通过冷凝或喷淋的方式模拟湿气影响。用来评估材料在颜色变化、光泽、裂纹、起泡、催化、氧化等方面的变化。
UV aging test machine does not simulate the full spectrum of sunlight, but simulate the destructive effects of sunlight. By controlling the main radiation fluorescent tubes in the solar spectrum ultraviolet to achieve. The test equipment simulated sunlight ultraviolet fluorescent lamp, but also thr influence of moisture can be simulated manner by condensation or spray. Materials used to assess changes in color change, gloss, cracking, blistering, catalytic oxidation or the like.

测试标准 TEST STANDARDS
ISO 4892.3;GB/T 16422.3; ASTM G 154 ; ASTM D 4674
