Marine environmental Effect of a Few encapsulating materials in Xi-sha

Abstract

objective To study the Marine environmental effect of a few encapsulating materials in South on the sea. Methods The exposure test of a few encapsulating materials was carried out under shelter on yongxing Island of Xisha in South for 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 kinds of materials with medium environmental adaptability in the tested; The correlation between high temperature test and marine atmosphere expose test is medium or lower than medium, and there Were kinds of materials, which acceleration factor of dielectric constant and volume resistance were more than 2 time S; There were kinds of materials, which correlation between humidity-heat test and marine atmosphere expose test was Medi Um or higher than medium, and there were kinds of materials, which acceleration factor of surface resistance were than 3, and there were kinds of materials, which acceleration factor of volume, resistance were than more 3 times. conclusion the environmental adaptability of the tested encapsulating Materials was medium under shelter on Xisha of South. The correlation between humidity-heat test and marine atmosphere expose test were preferable, and the humidity-heat test H As better performance degradation acceleration effect.
