Abstract

EL INVENTO PROPORCIONA UNA SOLUCION DE UNION QUE TIENE UN NIVEL DE SOLIDOS BAJO QUE PROPORCIONA UNAS CRACTERISTICAS DE TENSION MEJORADAS CUANDO SE USA CON ARENA. ESTA SOLUCION COMPRENDE UNA RESINA FENOLICA ALCALINA QUE SE CURA EN UNA TEMPERATURA AMBIENTAL CON UN ESTER FUNCIONAL COMO AGENTE CURATIVO. TAMBIEN SE DISPONE DE UNOS BAÑOS SIN MEZCLA QUE COMPRENDEN ARENA, UNA SOLUCION DE UNION QUE TIENE UN NIVEL BAJO DE SOLIDOS, UN AGENTE DE CURACION. ESTOS BAÑOS CON UN BAJO NIVEL DE SOLIDOS SE OBTIENEN POR LA ADICION SEPARADA DE UN DISOLVENTE. LOS METODOS PARA PRODUCCION DE LOS MOLDES DE FUNDICION Y LOS NUCLEOS, INCLUIDOS ESTOS PROCEDIMIENTOS, DONDE EL AGUA DILUIDA SE USA PARA REDUCIR LOS CONTENIDOS EN SOLIDOS DE SOLUCIONES DE ALTO CONTENIDO RELATIVO EN SOLIDOS.
