Abstract

PARA PRODUCIR PIGMENTOS DE BRILLO SOBRE LA BASE DE SUBSTRATO DE SILICATO EN FORMA DE PLAQUITAS PROVISTOS CON MULTIPLES CAPAS, LOS SUBSTRATOS YA RECUBIERTOS CON UNA PRIMIERA CAPA DE OXIDO DE METAL SIN COLOR O DE ABSORCION SELECTIVA SON: (A) PRIMERO CUBIERTOS CON UNA SEGUNDA CAPA, DE ABSORCION NO SELECTIVA COMPUESTA ESENCIALMENTE DE CARBON, METAL Y/O OXIDO METAICO, Y ENTONCES (B) SE RECUBREN, SI ASI SE REQUIERE, CON UNA TERCERA CAPA DE OXIDO DE METAL SIN COLOR O DE ABSORCION SELECTIVA. LA CAPA (ETAPA A) DE CARBON SE APLICA MEDIANTE DESCOMPOSICION TERMICA DE HIDROCARBUROS OXIGENADOS QUE CONTIENEN AL MENOS UN ATOMO DE OXIGENO POR CADA PAR DE ATOMOS DE CARBON. LA CAPA (ETAPA A) METALICA SE APLICA MEDIANTE DESCOMPOSICION DE FASE GASEOSA DE COMPUESTOS VOLATILES DE LOS METALES INDICADOS EN UN GAS INERTE. LA CAPA (ETAPAS A Y/O B) DE OXIDO METALICO SE APLICA MEDIANTE DESCOMPOSICION DE FASE GASEOSA DE COMPUESTOS METALICOS DE LOS METALES MENCIONADOS EN LA PRESENCIA DE OXIGENO, VAPOR O MEZCLA DE AMBOS.EN EL CASO (A), LAS CAPAS INDICADAS SON APLICADAS SOBRE SUBSTRATOS YA RECUBIERTOS CON UNA PRIMERA CAPA DE OXIDO METALICO Y EN EL CASO (B), LAS CAPAS INDICADAS SE APLICAN SOBRE SUBSTRATOS CUBIERTOS CON UNA SEGUNDA CAPA (A) DE ABSORCION NO SELECTIVA. SE DESCRIBEN TAMBIEN PIGMENTOS ESPECIALES, LA PRODUCCION Y UTILIZACION DE TALES PIGMENTOS DE BRILLO PARA LACAS DE COLOREAR, TINTAS DE IMPRENTA, PLASTICOS, COMPOSICIONES COSMETICAS DECORATIVAS, PRODUCTOS DE VIDRIO Y CERAMICOS.
