Description

Technical Field

[0001] The utility model relates to the field of coating damage, and more specifically, to an ultraviolet accelerated damage test device for coatings. Background Art

[0002] As an important means to protect the substrate from environmental erosion, the weather resistance of the coating is one of the key indicators for evaluating the coating quality. In the natural environment, ultraviolet rays are one of the main factors causing coating aging. Therefore, developing an accelerated damage test device that can simulate the influence of ultraviolet rays in the natural environment is of great significance for quickly evaluating the weather resistance of coatings.

[0003] At present, there are various types of ultraviolet accelerated aging test chambers on the market. They simulate the ultraviolet part of sunlight by using ultraviolet lamps with different wavelengths, and adjust environmental factors such as temperature and humidity through a control system to accelerate the coating aging process.

[0004] The existing test devices can test fewer coatings synchronously, and the test plates with coatings are not very convenient to install. When subjected to vibration, the test plates are likely to fall off, affecting the test results. Summary of the Utility Model
