Abstract
Una pistola de recubrimiento en polvo electrostática disocia una mezcla de aire y gas presurizada en una pluralidad de corrientes de rociado separadas, electrostáticamente cargadas para lograr un alto grado de deflexión reducida y direcciona. Las partículas en polvo de la mezcla pueden estar electrostáticamente cargadas mientras están dentro de una o más cámaras de la pistola ya sea mediante un campo electrostático CD aplicado o por ficción. Las trayectorias de flujo recorridas por las corrientes de rociado, pueden ser arregladas y/o orientadas de forma que se recubra ventajosamente con el polvo una configuración particular de superficie, tal como el interior de un contenedor. Alternativamente, la carga electrostática de las partículas en polvo pueden ocurrir a través de una pluralidad de electrodos localizados exteriormente, con respecto a la pistola, con al menos un electrodo externo asociado a cada corriente de rociado. Para reducir más la deflexión, la mezcla puede ser pulverizada por la pistola de una manera pulsátil. Adicionalmente, los campos electrostáticos creados mediante los electrodos externos pueden ser pulsados entre una condición de 'apagado' y 'encendido', durante el rociado.An electrostatic powder coating gun dissociates a pressurized gas-air mixture into a plurality of separate, electrostatically charged spray streams to achieve a high degree of reduced deflection and directs. Powder particles in the mix can be electrostatically charged while inside one or more gun chambers either through an applied DC or fictional electrostatic field. The flow paths traveled by the spray streams can be arranged and / or oriented so that a particular surface configuration, such as the interior of a container, is advantageously coated with the powder. Alternatively, electrostatic charging of the powder particles can occur through a plurality of externally located electrodes, relative to the gun, with at least one external electrode associated with each spray stream. To further reduce deflection, the mixture can be sprayed by the gun in a pulsating manner. Additionally, electrostatic fields created by the external electrodes can be pulsed between an 'off' and 'on' condition, during spraying.
