Abstract

PROCEDIMIENTO PARA REDUCIR LA PERMEACION DE CUERPOS HUECOS SOPLADOS A PARTIR DE PLASTICOS TERMOPLASTICOS, ESPECIALMENTE POLIETILENO DE ALTA DENSIDAD (HDPE) Y DE ALTO PESO MOLECULAR, EN QUE SE EXPANDE UNA PREFORMA EN FORMA DE MANGA DENTRO DEL MOLDE DE SOPLADO MEDIANTE UN GAS DE SOPLADO, DE MANERA QUE QUEDE AJUSTADO AL CONTORNO INTERIOR DEL MOLDE DE SOPLADO, Y SE SOMETE EL CUERPO HUECO, A CONTINUACION A LA ACCION DE UN GAS REACTIVO DE TRATAMIENTO, CUYO PROCEDIMIENTO ESTA CARACTERIZADO PORQUE EL CUERPO HUECO SE EXPONE A UNA TEMPERATURA DE SU SUPERFICIE INTERIOR DE, COMO MINIMO, 110JC, AL GAS REACTIVO DE TRATAMIENTO EN UN MOLDE POSTENFRIAMIENTO.
