Abstract

UNA COMPOSICION AGLUTINANTE PARA LA PRODUCCION DE ARTICULOS DE MATERIAL PARTICULADO AGLUTINADO COMO POR EJEMPLO NUCLEOS O MOLDES DE FUNDICION QUE CONTIENE UNA SOLUCION ACUOSA ALCALINA DE UNA RESINA DE ALDEHIDO CON FENOL DE RESOL, UN OXIANION QUE PUEDE FORMAR UN COMPLEJO ESTABLE JUNTO CON LA RESINA Y PIRROLIDONA O UNA PIRROLIDONA SUSTITUIDA EN LA POSICION N Y LA CANTIDAD DE ALCALI PRESENTE EN LA SOLUCION ES SUFICIENTE PARA EVITAR SUSTANCIALMENTE LA FORMACION DE UN COMPLEJO ESTABLE ENTRE LA RESINA Y EL OXIANION. LOS ARTICULOS AGLUTINADOS SE PRODUCEN HACIENDO PASAR GAS DE DIOXIDO DE CARBONO A TRAVES DE LOS ARTICULOS FORMADOS A PARTIR DE LA MEZCLA DEL MATERIAL PARTICULADO Y DE LA COMPOSICION AGLUTINANTE PARA ASI PROVOCAR LA FORMACION DE UN COMPLEJO ESTABLE Y EL ENDURECIMIENTO DE LA RESINA.
