Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA ELABORACION DE CUERPOS HUECOS A BASE DE MATERIAL SINTETICO TERMOPLASTICO, CUYAS PAREDES POR MOTIVOS DE INFLUJO DE LAS PROPIEDADES DE PERMEABILIDAD SON SOMETIDOS A UN TRATAMIENTO CON UNA MEZCLA DE GAS QUE CONTIENE FLUOR. EL PROCEDIMIENTO ES UTILIZABLE ESPECIALMENTE SOBRE RECIPIENTES DE COMBUSTIBLE, PARA REDUCIR LA PERMEABILIDAD DE SUS PAREDES ESPECIALMENTE DE FORMA INDEPENDIENTE DEL CONTENIDO EN ALCOHOL DEL COMBUSTIBLE. PARA ELLOS SE HAN PREVISTO DOS ETAPAS DE TRATAMIENTO, DONDE EN LA PRIMERA ETAPA SE TRABAJA CON UNA MEZCLA DE GAS, QUE CONTIENE FLUOR Y OXIGENO. EN LA SEGUNDA ETAPA SE UTILIZA DE FORMA TEMPORALMENTE POSTERIOR A UN TRATAMIENTO QUE TIENE LUGAR A CONTINUACION UNA MEZCLA DE GAS, QUE CONTIENE TAMBIEN FLUOR, PERO SIN EMBARGO ESTA LIBRE DE OXIGENO.
