Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE MODIFICACION DEL PODER DE ENFRIAMIENTO DE UNA SOLUCION ACUOSA DE AL MENOS UN POLIMERO ORGANICO HIDROSOLUBLE CON UNA TEMPERATURA CRITICA DE SOLUBILIDAD INFERIOR (LLAMADA ALFA CST), CON EL FIN DE SU UTILIZACION PARA EL TEMPLE DE ALEACIONES METALICAS CARACTERIZADA EN QUE SE INTRODUCE EN DICHA SOLUCION UN ADITIVO HIDROSOLUBLE QUE MODIFICA DICHA TEMPERATURA CRITICA. PARA DISMINUIR EL ALFA CST DE LA SOLUCION, SE UTILIZA PREFERENTEMENTE COMO ADITIVO UNA SAL MINERAL DE UN ACIUDO MINERAL U ORGANICO EN UNA CONCENTRACION COMPRENDIDA ENTRE 0.1 Y 200 G/L, ELIGIENDOSE LA SAL DE ENTRE LAS SALES DE METALES ALCALINOS Y ALCALINOTERREOS, COMPRENDIDOS EL MAGNESIO Y EL CINC. PARA AUMENTAR EL ALFA CST DE LA SOLUCION, SE PROCEDE A UNA ADICION DE UN DERIVADO ORGANICO HIDROSOLUBLE, DE UNA CONCENTRACION COMPRENDIDA ENTRE 0.01 Y 200 G/L, ELEGIDO DE ENTRE LOS COMPUESTOS ALIFATICOS CON AL MENOS UNA FUNCION ELEGIDA DE ENTRE LOS ALCOHOLES, ACIDOS, ALDEHIDOS, AMIDAS Y AMINAS.
