摘　　要：依据电力系统污区分布,通过静态接触角的测量及HC喷水分级法研究了涂层的厚度、盐密及灰密对涂层憎水迁移性的影响。结果表明:涂层的厚度、盐密对PRTV涂层的憎水迁移性影响较小,而涂层灰密对其憎水迁移性影响较大,灰密越大涂层的憎水迁移越困难。研究结果对涂层在污秽地区的运行具有指导意义,并为深入探讨灰密和盐密对防污闪涂料电气性能的影响提供理论依据。According to the distribution of dirty area in power system,the influence of coating thickness and density of salt and dust on migration of hydrophobicity coating is analyzed by measuring the static contact angle and using HC water spray classification method.The results show that coating thickness and density of salt have little effect on migration of hydrophobicity for PRTV coating while the density of dust have large effect;the lager the density of dust is,the more difficulty the PRTV coating moves.The study results provide an important guiding meaning for the coating operation in dirty area and a basis theory for investigating the influence of density of salt and dust on electricity property of anti-flashover coating.
