Abstract The electrostatic powder application system is designed to deliver powder to the work area in even well packed layers. It delivers the powder from a storage container using compressed air, forces the particles through an electric field, and sprays them onto a grounded plate. A qualitative experiment into the feasibility and performance of the system is presented. A model of the particle charging mechanism, and the particle charge draining mechanism is also presented. Tle experiment finds that a 20 mil layer of packed powder is repeatedly achievable, and that the system has powder clogging problems. (Auth abstract) [References: 4]
