Abstract

LA INVENCION SE REFIERE A UN PROCESO DE FABRICACION DE POLVOS ORDENADOS. ESTE PROCESO DE FABRICACION DE POLVOS ORDENADOS OBTENIDOS A PARTIR DE PARTICULAS DE DIFERENTES TAMAÑOS QUE PERTENECEN A AL MENOS DOS POBLACIONES DE PARTICULAS DE TAMAÑOS SENSIBLEMENTE HOMOGENEOS QUE COMPRENDEN RESPECTIVAMENTE AL MENOS UNA POBLACION DE PARTICULAS NUCLEOS Y AL MENOS UNA POBLACION DE PARTICULAS SATELITES, CARACTERIZADO EN QUE SE REALIZA EN UNA PRIMERA ETAPA UNA DISPERSION SENSIBLEMENTE HOMOGENEA DE CADA POBLACION EN UN LIQUIDO DE DISPERSION; Y, EN UNA SEGUNDA ETAPA, SE PULVERIZA DICHA DISPERSION EN LAS CONDICIONES APROPIADAS PARA OBTENER LA FORMACION DICHO POLVO ORDENADO. ESTE PROCESO PERMITE OBTENER POLVOS ORDENADOS QUE SE CARACTERIZAN POR UN RECUBRIMIENTO MUY REGULAR DE LAS PARTICULAS NUCLEOS CUALQUIERA QUE SEA SU FORMA, EN GRAN CANTIDAD, Y DE BAJO COSTE.
