Recovery Behavior of Hydrophobicity of Silicone Rubber for Polymer Insulator Housing Deposited with Contaminant

摘要

This paper deals with recovery behavior of hydrophobicity of silicone rubber for polymer insulator housing after depositing artificial contaminant on its surface. Artificial contaminant was prepared based on TONOKO and soldium chloride. Recovery behavior of hydrophobicity of a specimen deposited with artificial contaminant was evaluated by receding contact angle and diameter of water droplets dropped on its surface. The specimen kept under high temperature and dry conditions recovered hydrophobicity faster than the specimen kept under low temperature and high humidity conditions.
