电绝缘硅橡胶憎水性的测试方法

Test Methods for Hydrophobicity of Electrical Insulating Silicone Rubber

对现有测试标准及文献中关于憎水性、憎水迁移性、憎水恢复性、憎水减弱性和人工加速老化在外绝缘硅橡胶憎水特性测试的要求及要点进行了总结。进行憎水性测试时,需根据实际测试环境选择静态接触角法或喷水分级法;进行憎水迁移性试验时,则需要根据适用的法规选择对应的污秽。

The requirements and main points of the existing test standards and literature on the hydrophobicity,hydrophobic migration,hydrophobic recovery,hydrophobic loss and artificial accelerated aging tests of the hydrophobic properties of external insulating silicone rubber are summarized.When testing the hydrophobicity,the static contact angle or water spray classification method shall be selected according to the actual environment;when testing the hydrophobicity migration,the corresponding pollution shall be selected according to the applicable regulations.
