聚乙烯具有良好的电气绝缘性能,制成的聚乙烯管材有很高的表面电阻,在一定条件下,例如:当管壁受到接触磨擦或高速流过干燥与绝缘的介质时,以及在电场感应作用下容易产生静电荷。当静电荷达到一定能量后,能使人体遭到电击,煤矿中瓦斯积聚到相当浓度后,具有因静电放电的火花触发瓦斯燃烧的潜在危险。
Polyethylene has good electrical insulation properties, made of polyethylene pipe has a very high surface resistance, under certain conditions, for example: when the wall is subject to contact friction or high-speed flow through the dry and insulated media, as well as in the electric field induced Under the action prone to electrostatic charge. When the electrostatic charge reaches a certain amount of energy, the human body can be subjected to electric shock. After the gas accumulates to a considerable concentration in the coal mine, it has the potential danger of triggering gas combustion due to the spark of electrostatic discharge.
