耐温135℃紫外光交联聚乙烯绝缘电线的耐油及耐化学品性能

摘要

According to GB/T 12528 -2008, the mechanical and voltage resistant properties of the UV light cross-linking polyethylene insulating wire at 135℃ were investigated after its immersion in mineral oil, fuel oil, acid, alkali or salt solutions at different times. The results indicated that the UV light cross-linking polyethylene at 135 ℃ insulation can not be used safely in mineral oil environment, but it can be used in fuel oil, acid, alkali and salt conditions.%参考GB/T 12528-2008,考查了耐温135℃紫外光交联聚乙烯绝缘电线在矿物油、燃料油、酸碱盐溶液中浸泡不同时间后的机械性能变化和耐电压试验研究.结果表明,耐温135℃紫外光交联聚乙烯材料暂时不适合在有矿物油的环境中使用,在燃料油存在的环境中、酸、碱和盐的环境中均可正常使用.
