煤矿使用塑料管在我国近几年有很大发展,使用范围已从洒水降尘扩大到供排水、压风、喷浆及瓦斯抽放等各个方面。 两个物体相互摩擦就要产生静电荷。如果该物体不是导体,产生的静电荷就不易泄漏,极易积聚在其表面。一个表面带电的非导体和一个接地体接触时(例如人的手指接触带了 The use of plastic pipe in coal mines in our country has greatly developed in recent years, the scope of use has expanded from sprinkler dust to water supply and drainage, air pressure, spray and gas drainage and other aspects. Friction between two objects to generate electrostatic charge. If the object is not a conductor, the electrostatic charge generated is not easy to leak, easily accumulate on the surface. A surface-charged non-conductor and a grounding contact (such as human finger contact with
