Example Embodiment
[0023] Example 1: Hainan Wanning Experimental Station belongs to a hot and humid marine atmosphere, with climate characteristics of high temperature, high humidity, high salt fog, and high solar radiation. The design of the simulated accelerated test environment spectrum focuses on the comprehensive effect of the four environmental factors of solar radiation, salt spray, temperature and humidity that play a leading role in coating aging. The environmental spectrum block is composed of damp heat test, ultraviolet condensation test, and salt spray test. According to the established natural environment spectrum, the equivalent transformation determines the magnitude of the test parameter value, the action time and the action sequence to form a simulated accelerated test environment spectrum, see figure 1 ,among them:
[0024] The action sequence of the damp heat test-ultraviolet condensation test-salt spray test reflects the actual situation of the coating being exposed to high humid...
