【摘要】：广东地区所处的亚热带气候环境对室温硫化硅橡胶(RTV)防污闪涂料的运行具有重要影响。为此,对广东地区不同环境下运行了4~7 a的RTV防污闪涂料进行了试验,从涂料绝缘子表面状态、憎水性、憎水迁移性等方面分析了高温高湿、紫外线辐射及多雨水环境对RTV防污闪涂料运行性能的影响,并采用Fourier变换红外光谱分析了RTV涂料中有机硅含量的变化。结果表明,在高温高湿、强紫外线辐射、强降雨量的作用下,RTV防污闪涂料表面状态劣化较为严重。运行时间越长,RTV涂料的憎水性及憎水迁移性越差,市区附近运行了7 a的RTV涂料已丧失憎水迁移性。不同污染源对于RTV涂料的性能变化也有一定影响;相同运行时间下,运行于市区附近的RTV涂料性能要好于运行于水泥厂附近的RTV涂料。
[Abstract]:The environment of subtropical climate in Guangdong area has an important influence on the operation of RTV (room temperature vulcanized silicone rubber) anti-pollution flashover coatings. For this reason, the RTV anti-pollution flashover coating which has been operated for 4 ~ 7 years in different environments in Guangdong area has been tested. The high temperature and high humidity of the coating insulator are analyzed in terms of its surface state, hydrophobicity and hydrophobicity, etc. The effects of ultraviolet radiation and multi-Rain Water environment on the performance of the anti-pollution flashover coatings were studied. The changes of organosilicon content in the coatings were analyzed by Fourier transform infrared spectroscopy (FTIR). The results show that the surface condition of RTV anti-pollution flashover coating is worse under the action of high temperature and high humidity, strong ultraviolet radiation and strong rainfall. The longer the running time is, the worse the hydrophobicity and hydrophobicity of RTV coatings are. Under the same operating time, the performance of RTV coating running near urban area is better than that of RTV coating running near cement factory.
