Abstract

LA INVENCION PROPORCIONA UN METODO DE LIMPIEZA EN EL CUAL PUEDE SER USADO UN DISOLVENTE TAL COMO DIOXIDO DE CARBONO DENSIFICADO PARA LIMPIEZA RAPIDA Y EFICAZ, PERO CON DAÑO REDUCIDO A COMPONENTES SOLIDOS TALES COMO BOTONES. EL METODO COMPRENDE EL CONTACTO DE UN SUSTRATO QUE HA DE SER LIMPIADO CON UN PRIMER FLUIDO, LA ELIMINACION DEL CONTACTO DEL PRIMER FLUIDO CON EL SUSTRATO MIENTRAS SE LE SUSTITUYE POR UN SEGUNDO FLUIDO Y LA RECUPERACION DEL SUSTRATO BIEN LIBRE DEL PRIMERO Y DEL SEGUNDO FLUIDOS Y DEL CONTAMINANTE. EL PRIMER FLUIDO ES UN GAS DENSIFICADO MIENTRAS QUE EL SEGUNDO FLUIDO ES UN GAS COMPRIMIDO. UNA REALIZACION PREFERIDA DEL METODO INCLUYE EL USO DE UN TRATAMIENTO PREVIO DISEÑADO PARA SER COMPATIBLE CON EL PRIMER FLUIDO DENSIFICADO.
