Description

Technical Field

[0001] The utility model relates to the technical field of light aging testing, in particular to a light aging testing device for aluminum alloy after dyeing. Background Art

[0002] The surface of aluminum alloy is prone to form an oxide film under natural or artificial conditions. On the basis of the oxide film, the aluminum alloy is colored to obtain a film layer of various colors to improve the decorative effect of the aluminum alloy surface. However, due to the presence of tiny holes or gaps in some aluminum alloy parts, acid inevitably enters the gaps during the anodizing process and is not easy to be cleaned out. In the subsequent dyeing process, the acid will flow out, resulting in abnormalities such as dyeing color difference. Therefore, after the parts are anodized and before dyeing, the acid entering the holes or gaps is cleaned out by adding a surface conditioner to avoid abnormal dyeing. After adding the surface conditioner, the dyeing is more uniform and the light resistance is better. Then, the light aging resistance of the aluminum alloy surface after adding the surface conditioner is tested by an aging test chamber. Most of the existing aging test chambers can only be irradiated from the top when simulating ultraviolet aging. The test samples are stationary in the aging test equipment and cannot be fully exposed to the ultraviolet light, which reduces the accuracy of the detection. Utility Model Content
