Experimental studies on the effect of moisture content and volume resistivity on electrostatic behaviour of pharmaceutical powders.
Abstract Pharmaceutical powders are mainly organic materials and are likely to be charged due to repeated inter-particle and particle-wall contacts during industrial processes. This study experimentally investigated the effect of moisture content (ranging from approximately 1.8 to 30wt.%) on tribocharging behaviour of pharmaceutical granules, as well as their apparent volume resistivity. The tribocharging behaviour of pharmaceutical granules was investigated using […]
