Abstract
ara a fabricação de machos de areia para processos de fundição de metais pelo Processo da Câmara Fria de uretano, a trimetilamina gasosa é conduzida através de partes de um dispositivo de medição (3) peso, com base na quantidade de areia usada por macho em uma máquina de disparo de machos (4), em que ela é colocada em contato com a areia e, antes da introdução da trimetilamina gasosa na máquina de disparo de machos (4), um gás de purga é introduzido, o relacionamento entre a trimetilamina e o gádade T de trimetilamina, a quantidade L dos gás de purga usado fica na relação de T:L de 1:1000 a 1:10000.For the manufacture of sand cores for metal smelting processes by the Urethane Cold Chamber Process, gaseous trimethylamine is conducted through parts of a weight measuring device (3) based on the amount of sand used by the male in a tapping machine (4), in which it is placed in contact with the sand and, before the introduction of gaseous trimethylamine in the tapping machine (4), a purge gas is introduced, the relationship between trimethylamine and the T gas of trimethylamine, the amount L of the purging gas used is in the T: L ratio from 1: 1000 to 1: 10000.
