Abstract
Un método y un aglomerante para fabricación de corazones y/o moldes de arena para fundición que comprende (1) un silicato de metal alcalino, por ejemplo NaSiO2 (2) un hidróxido de metal alcalino, por ejemplo NaOH); (3) un almidón (por ejemplo, almidón de maíz o de tapioca); (4) un silicato de alquilo, por ejemplo silicato de tetraetilo; y (5) agua. Se mezcla la arena con el aglomerante y se introduce por medio de aire a un molde para corazones conocido corno de caja fría, y se hace pasar una corriente de aire caliente para evaporar los líquidos de la arena, con lo cual, se endurece el corazón o molde y se puede utilizar en el proceso de fundición. Este aglomerante puede utilizarse en fundiciones de aleaciones de aluminio y otros metales con grandes ventajas sobre los aglomerantes del arte previo, tales como poder utilizar varios tipos de arena y usar los herramentales y equipos de caja fría que se usan con otros aglomerantes, con bajos costos de operación y mantenimiento.
