| Objective To study the marine environmental effect of a few encapsulating materials in South China Sea. Methods The exposure test of a few encapsulating materials was carried out under shelter on Yongxing Island of Xisha in South China Sea for 24 months. The environmental effect and the environmental adaptability were analyzed. At the same time, the high temperature test and the humidity-heat test were completed. The correlativity between the environmental test and the artificial simulation test was compared and analyzed. Results There were 5 kinds of materials with better environmental adaptability and 10 kinds of materials with medium environmental adaptability in the tested 16 materials; the correlation between high temperature test and marine atmosphere expose test was medium or lower than medium, and there were 11 kinds of materials, which acceleration factor of dielectric constant and volume resistance were more than 2 times; there were 11 kinds of materials, which correlation between humidity-heat test and marine atmosphere expose test was medium or higher than medium, and there were 10 kinds of materials, which acceleration factor of surface resistance were more than 3 times, and there were 14 kinds of materials, which acceleration factor of volume resistance were more than 3 times. Conclusion The environmental adaptability of the tested encapsulating materials was medium under shelter on Xisha of South China Sea. The correlation between humidity-heat test and marine atmosphere expose test were preferable, and the humidity-heat test has better performance degradation acceleration effect. |
