Experimental Research of Impact of Fine Water Mist on Antistatic Property of Non-metallic Pipes
XUE Shaoqian
Abstract：Based on the principle of reducing the surface resistance of pipes by water, tests were carried out on the internal and external surface resistivity of PVC and PE pipe specimen commonly used in coal mines under different pressures of the fine water mist. The study results showed that the average resistivity of the internal and external surface of both PVC and PE pipes decreased in an exponential function with the increase of spray pressure;under the same conditions, the average resistivity of the internal surface of PVC and PE pipes was smaller than that of their external surface, and the surface resistivity of PVC pipe was smaller than that of PE pipe. In the test, PVC pipe meets the requirements of antistatic property, so it is more suitable for use in coal mines.
