摘要: Abstract Electrostatic phenomena are commonly observed in the processing of solids. However, working mechanism electrostatic charge generation for single granules and particularly, their equilibria have not been properly understood. In this work, repeated-sliding charging experiments with were investigated particularly from perspective triboelectrification equilibrium. Factors including granule length-ratio, sliding face shape, times, area, velocity, front-facing edge, sliding-plate inclined-angle found to an obvious effect on generation. Length-ratio area significant effects as evolved toward equilibrium state. Equilibrium is suggested a variable expressing propensity material. addition, under same conditions, semi-cylindrical generates greater than rectangular granule.
