Abstract

METODO DE PRODUCIR UN OXIDRATO LIGERO DE ALUMINIO ACTIVO Y DISPERSIVO. CONSISTE EN PASAR, DE FORMA CONTINUA, AL INTERIOR DE UN REACTOR POR MEDIO DE UNA CORRIENTE DE AIRE CALIENTE SECO Y, BAJO UNA FLUIDIZACION Y CON UNA FUERTE DISPERSION, UN TRIHIDROXIDO DE ALUMINIO, CALENTANDOLO ENTRE 400 Y 600GC, PARA SER DESHIDRATADO POR CHOQUE; SEPARAR POR MEDIOS MECANICOS APROPIADOS EL OXIDO LIGERO DE ALUMINIO QUE SALE DEL REACTOR; DISPERSAR EL MISMO DENTRO DE UN AGUA LIGERAMENTE ACIDA O BIEN LEVEMENTE BASICA Y REHIDRATAR POR MEDIO DE CALENTAMIENTO; Y EFECTUAR EL SECADO A TEMPERATURA POR DEBAJO DE LA TEMPERATURA DE ACTIVACION. TIENE APLICACION EN LA PRODUCCION DE CUERPOS MOLDEADOS.
