Abstract

EL INVENTO PROPORCIONA UNOS METODOS PARA TRATAR ARENA OBTENIDA DE MOLDES DE FUNDICION DESMANTELADOS Y NUCLEOS QUE CONTIENEN UNA AGRAVILLADORA DERIVADA DE UNA RESINA FENOLICA ALCALINA DE ESTER. EL TRATAMIENTO DE LA ARENA CON UNA SOLUCION SALINA, PARTICULARMENTE UNA SOLUCION ACUOSA, AUMENTA LA TENSION DE LOS MOLDES DE FUNDICION Y LOS NUCLEOS PRODUCIDOS ALLI MISMO CON ARENA NO TRATADA. LOS METODOS PARA LA PRODUCCION DE LOS NUCLEOS DE FUNDICION Y LOS MOLDES QUE INCORPORAN TAL TRATAMIENTO SE PROVEEN TAMBIEN POR ESTE INVENTO TAL COMO LAS FORMULACIONES DE BAÑO SIN MEZCLA.
