Abstract

PROCEDIMIENTO DE PREPARACION DE UN MATERIAL DE ARENA PARA MACHOS DE MOLDE EN FUNDICIONES DE METALES. CONSISTE EN LA PREPARACION DE UN MATERIAL FORMADO CON ARENA DE MACHO MEZCLADA CON UNA RESINA Y UN CATALIZADOR, DE FORMA DE CONSEGUIR UNA DURACION DE ALMACENAMIENTO PROLONGADA QUE EVITA EL COMIENZO DE LA REACCION DE POLIMERIZACION Y CONSEGUIR, SIN EMBARGO, UN ENDURECIMIENTO RAPIDO DEL MISMO AL SER ALCANZADO O REBASADO UN UMBRAL DESEADO DE LA TEMPERATURA. SE CONSIGUE MEZCLANDO LA ARENA CON UN MATERIAL AGLOMERANTE EN PROPORCION ENTRE 0,5% Y 5% DE AQUELLA Y UN CATALIZADOR EN CANTIDAD COMPRENDIDA ENTRE EL 5% Y EL 40% DEL AGLOMERANTE. EL AGLOMERANTE ES UNA RESINA ENDURECIBLE Y EL CATALIZADOR INCLUYE UNA SAL DE COBRE O ALUMINIO DE ACIDO BENCENO-SULFONICO O TOLUENO-SULFONICO O MEZCLA DE AMBAS. EL ENDURECIMIENTO SE LOGRA CALENTANDO EL MOLDE, DONDE SE HA REALIZADO EL MACHO, EN HORNO CONVENCIONAL O DE MICROONDAS A TEMPERATURAS DE POR LO MENOS 121<025>C Y DURANTE UN TIEMPO QUE OSCILA ENTRE MENOS DE UN MINUTO Y CINCO MINUTOS.
