Abstract

PROCEDIMIENTO PARA LA PULVERIZACION ELECTROSTATICA DE MEZCLAS DE DIFERENTES POLVOS INORGANICOS CON ELEVADA RESISTENCIA SUPERFICIAL, ESPECIALMENTE DE POLVOS DE ESMALTE Y COLORANTES SOBRE SUSTRATOS METALICOS. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, ANTES DE LA PULVERIZACION ELECTROSTATICO, SE FORMAN UNOS AGLOMERADOS UNITARIOS; SEGUNDA, ANTES DE LA MOLTURACION DE LOS AGLOMERADOS UNITARIOS SE LES AGREGA COMPUESTOS ORGANICOS DE SILICIO QUE REACCIONAN CON LOS GRUPOS SI-OH DE LOS POLVOS INORGANICOS Y, ADEMAS, COMPUESTOS ORGANICOS INSATURADOS, QUE CONTENGAN PREFERENTEMENTE GRUPOS HIDROXILO; Y POR ULTIMO, SE MOLTURAN LOS AGLOMERADOS UNITARIOS, HASTA DEJARLOS REDUCIDOS A POLVO FINISIMO. DE APLICACION EN LA INDUSTRIA DEL ESMALTADO.
