环境湿度对硅橡胶材料憎水迁移性的影响
Influence of Ambient Humidity on Hydrophobicity Transfer of Silicone Rubber Material
摘要
Abstract
Hydrophobicity and the unique hydrophobicity transfer property of silicone rubber material are the basic reason why composite insulators can prevent pollution flashover.Hydrophobicity transfer property of silicone rubber material is greatly influenced by ambient humidity.To deeply investigate the problem mentioned above,ambient humidity was controlled using saturated salt solution method,and the hydrophobicity status of the pollution surface was measured using static contact angle method.The results show that hydrophobicity transfer speed of HTV（high temperature vulcanization）slows down in high humidity environment;as to the two recommended pollutants by IEC standard,the moisture absorption ability of kaolin is better than kieselguhr,ambient humidity has a great impact on the hydrophobicity transfer property when the inert material is kaolin;the moisture absorption ability of the soluble substance in the surface pollutants has a great impact on the hydrophobicity transfer property,when surface pollutants contain sugar and soluble salts like NaCl,the hydrophobicity transfer speed slows down and the stable contact angle is low.关键词
