Material repulsion by electrostatic charge

摘要

An apparatus and method for reducing material accumulation on processing equipment caused by electrostatic charge. By proper selection of materials, the equipment is designed to automatically develop a charge of the same polarity as that on the material being processed and thereby repel the material. The selection can be based on the relationship of the materials in the Triboelectric Series. The processing equipment is also electrically insulated from discharge paths so that the charge developed will not be dissipated or require high current generation to maintain the voltage required to repel the material particles.
