Abstract

PROCEDIMIENTO DE MOLDEAR Y VULCANIZAR NEUMATICOS Y OTROS ARTICULOS DE CAUCHO Y SIMILARES.CONSISTE EN, CON AYUDA DE UNA MEMBRANA O VEJIGA Y CON UNA PRENSA, IMPRIMIR FORMAS NEGATIVAS A LA PIEZA BRUTA DE LA CUBIERTA BAJO ALTA PRESION Y SE REALIZA VULCANIZACION. LA VEJIGA SE PROVEE DE UN LUBRICANTE PARA IMPEDIR EL PEGADO DE LA CUBIERTA MOLDEADA Y VULCANIZADA. ESTE LUBRICANTE ES UNA PELICULA DE AGENTE DE DESMOLDES RETICULADO, ENDURECIDO, ELASTICO Y MUY ADHERENTE. LA PELICULA SE UNE A LA VEJIGA POR INTERACCIONES QUIMICAS ANTES DEL MOLDEO Y EL VULCANIZADO.LA PELICULA SE PRODUCE SOBRE LA VEJIGA EN LAS SIGUIENTES ETAPAS: A) APLICANDO EN EL EXTERIOR DE LA VEJIGA UNA MEZCLA DE AGENTE DE DESMOLDEO A BASE DE SILICONAS Y DE CAUCHO DE SILICONAS, POLIMERIZANDO EL ULTIMO BAJO LA INFLUENCIA DE LA HUMEDAD Y/O DEL CALOR, DISUELTA EN DISOLVENTES ORGANICOS; B) APLICANDO OPCIONALMENTE EN EL INTERIOR DE LA VEJIGA LA DISOLUCION DE LA ETAPA (A), EXCEPTO QUE NO CONTIENE NI CARGA NI LUBRICANTE; C) EXPONIENDO LA VEJIGAA AIRE QUE CONTIENE HUMEDAD Y/O CALOR PARA OBTENER UN RENDIMIENTO CURADO; Y D0 APLICANDO OPCIONALMENTEO.UN RECUBRIMIENTO LUBRICANTE COMO CAPA SUPERFICIAL EN LA PARTE SUPERIOR DEL RECUBRIMIENTO PRODUCIDO EN LAS ETAPAS (A) Y (C).
