Abstract

UN PROCESO PARA PRODUCIR UNA COMPOSICION DE REVESTIMIENTO EN POLVO QUE TIENE PARTICULAS EN POLVO DE LAS QUE AL MENOS EL 50% TIENEN UN TAMAÑO ENTRE 3 Y 5 MICRONES Y EL 100% ES MENOR O IGUAL DE 10 MICRONES. EL PROCESO INCLUYE LOS PASOS DE PREPARAR UN EXTRUDADO DE REVESTIMIENTO EN POLVO, REDUCIR EL EXTRUDADO A COPOS, FRESAR POR INYECCION EL REVESTIMIENTO EN POLVO A UN POLVO EN EL QUE AL MENOS EL 50% DE LAS PARTICULAS TIENEN UN TAMAÑO ENTRE 3 Y 5 MICRONES Y EL 100% DE ELLAS TIENE UN TAMAÑO MENOR O IGUAL A 10 MICRONES, Y SUMINISTRAR EL POLVO A UNA MEZCLA DE AGUA Y SURFACTANTE. LOS AGENTES DE CONTROL REOLOGICO Y DISPERSANTES SE ADICIONAN ENTONCES A LA MEZCLA.
