Abstract

Es un método que tiene por objeto la fabricación de machos de arena destinados a procesos de fundición de metales conforme al Proceso de Moldeadoen Frio en uretano, se conduce trimetilamina gaseosa a través de las piezas de un dispositivode medición (3) y luego, bajo una concentración que oscilaentre 0.01 y 0.12% en peso que se basa en la cantidad de arena utilizada por macho, se la introduce en una máquina productora de machos (4) donde se lapone en contacto con la arena, en tanto antes de introducir la trimetilamina gaseosa en la máquina (4) se introduce un gas purgante, mientras que larelación entre la trimetilamina y el gas purgante es tal que para una cantidad T de trimetilamina, la cantidad L de gas purgante oscilaentre 1:1000 y1000:1; T:L.It is a method that aims to manufacture sand cores for metal casting processes according to the Cold Molding Process in urethane, gaseous trimethylamine is conducted through the pieces of a measuring device (3) and then, under a concentration ranging from 0.01 to 0.12% by weight based on the amount of sand used per core, it is introduced into a core producing machine (4) where it is placed in contact with the sand, while before introducing the gaseous trimethylamine a purging gas is introduced into the machine (4), while the relationship between trimethylamine and purging gas is such that for a quantity T of trimethylamine, the quantity L of purging gas ranges between 1: 1000 and 1000: 1; T: L.
