Abstract

METODO DE PRODUCIR ARTICULOS MOLDEADOS A PARTIR DE UNMATERIAL RESINOSO POLIMERO. COMPRENDE: A) INYECTAR EN UNA CAVIDAD DE UN MOLDE, UNA MEZCLA QUE CONTIENE UN MATERIAL RESINOSO POLIMERO TERMOPLASTICO CAPAZ DE FLUIR; B) SOLIDIFICAR LA MEZCLA EN LA CAVIDAD DEL MOLDE, PARA FORMAR UN ARTICULO MOLDEADO; C) CONTACTAR LA SUPERFICIE INTERIOR DE LA CAVIDAL DEL MOLDE CON UN AGENTE DE DESMOLDEO ANTES O DURANTE LAS ETAPAS A) Y B); Y D) SEPARAR DEL MOLDE EL ARTICULO MOLDEADO. EL MATERIAL RESINOSO POLIMERO ES POLISULFURO O POLICARBONATO Y EL AGENTE DE DESMOLDEO ES UN COMPUESTO GLICOSIDICO QUE CONTIENE UN ESTER DE ACIDO GRASO. SE UTILIZA EN PROCESOS DE FABRICACION.
