摘要:
优异的憎水性是硅橡胶材料在电力设备中广泛应用的重要因素。按照标准规定的试验程序,在进行憎水性减弱试验时,出现了试样表面有油状附着层生成,憎水性随之丧失或明显减弱的现象。针对该现象设计、开展了多变量实验研究。实验结果表明,浸泡于不同实验用水中、处于不同实验温度和实验氛围下的一种高温胶和一种液体胶试样表面均有可能产生油状附着层,该附着层中至少含有细菌、真菌及其分泌物等,该附着层会使材料憎水性急剧下降或丧失。当试样表面附着层擦除后,憎水性立刻恢复。该附着层对材料憎水性试验结果和运行有重大影响,建议在硅橡胶材料生产、试验和运行过程中作为重点关注因素之一。
Abstract:
Silicone rubber is widely used in electrical equipment considering its excellent performance on hydrophobicity. However, when the reduction of hydrophobicity test was carried out according to the standard test procedure, glossy layer appeared on the test samples surfaces. Consequently, its hydrophobicity decreased sharply or eventually disappeared. In this paper, multivariate experimental research on this phenomenon was designed and accomplished. The obtained experimental results show that the glossy layer will possibly appear when test samples(one type of HTV and LSR)are dipped in different kinds of experimental water with different temperatures or environments. The glossy layer contains bacteria, fungi and their secretions and the hydrophobicity of silicone rubber will decrease sharply or even disappear. When the glossy layer is erased, the hydrophobicity will recover immediately. The glossy layer has significant influence on the hydrophobicity test and operation, and it is recommended that more attention should be paid to the glossy layer during the production, test and operation of silicone rubber.
