Abstract

PROCEDIMIENTO AUTOMATICO PARA DISOLVER QUIMICAMENTE ALAMBRE DE NUCLEO DE MOLIBDENO EN BOBINAS DE FILAMENTO DE TUNGSTENO PARA FUENTES DE LUZ, POR MEDIO DE UNA MEZCLA DE ACIDO NITRICO, ACIDO SULFURICO Y AGUA. CONSISTENTE EN COLOCAR LAS BOBINAS DE FILAMENTO DE TUNGSTENO EN UN RECIPIENTE DE REACCION HERMETICO QUE CONTIENE LA MEZCLA DE ACIDO Y QUE SE CONECTA A UN RETEN DE LIQUIDO. CUANDO SE INICIA LA REACCION DE DISOLUCION Y CUANDO SE HA FORMADO UN VACIO EN EL RECIPIENTE DE REACCION, CON RESULTADO DE QUE PARTE DEL OXIGENO EN EL AIRE CONTENIDO EN ESTE ULTIMO HA SIDO ABSORBIDO POR EL MONOXIDO DE NITROGENO FORMADO DURANTE LA REACCION DE SUPRESION DEL NUCLEO, SE INTRODUCE OXIGENO, MEEDIO AUTOMATICAMENTE, EN EL RECIPIENTE DE REACCION MIENTRAS SE MANTIENE EL VACIO FORMADO EN EL MISMO. EL SUMINISTRO DE OXIGENO SE CONTROLA POR DIPOSITIVOS DETECTORES DE PRESION, DISPUESTOS EN LA RETENCION DEL LIQUIDO.
