Abstract

METODO PARA FORMAR UN MOLDE O MACHO DE FUNDICION.COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE AÑADE A UN CUERPO DE ARENA O DE PARTICULAS REFRACTARIAS SIMILARES UN AGLUTINANTE QUE COMPRENDE UNA SOLUCION ACUOSA DE UNA SAL DE METAL ALCALINO DE UN ACIDO ORGANICO POLIVALENTE O DE UN ACIDO ORGANICO MONOVALENTE POLIMERIZADO; SEGUNDA, SE AÑADE HIDROXIDO DE METAL ALCALINO-TERREO; TERCERA, SE FORMA UN MOLDE O MACHO DE LA CONFIGURACION REQUERIDA A PARTIR DE LA MEZCLA RESULTANTE; Y POR ULTIMO, SE HACE PASAR UN GAS ACIDO A TRAVES DEL CUERPO RESULTANTE, CON LOQUE SE PRODUCE UNA REACCION DE CURADO QUE ALTERA EL EQUILIBRIO QUIMICO DEL CONJUNTO DE CONSTITUYENTES ORGANICOS E INORGANICOS, FORMANDOSE ASI UNA SAL METALICA POLIVALENTE INSOLUBLE DEL GAS ACIDO Y UN CEMENTO POLIMERO DEL ACIDO POLIVALENTE.
