Abstract

UN APARATO Y UN METODO PARA REFRIGERAR UNA PELICULA DE PLASTICO SOPLADO EXTRUIDA EN QUE LA SUPERFICIE INTERIOR DE LA BURBUJA DE PELICULA DELGADA SE PONE EN CONTACTO CON UN GAS DE REFRIGERACION ANHIDRO QUE NO CONTENGA VAPOR DE AGUA PARA ASI REFRIGERAR LA PELICULA EXTRUIDA Y QUE SE FORME UN GAS AGOTADO EN QUE UTILIZA UNA CAMARA MEZCLADORA 72 QUE TIENE UN PRIMER ORIFICIO DE ENTRADA 66 PARA CRIOGENO LIQUIDO TAL COMO NITROGENO LIQUIDO Y UN SEGUNDO ORIFICIO DE ENTRADA 68 PARA EL GAS AGOTADO POR FORMAR EL GAS DE REFRIGERACION. LA CAMARA MEZCLADORA 72 PUEDE FORMAR PARTE DE UN EYECTOR 74 QUE PUEDE ESTAR COLOCADO DENTRO DE O FUERA DE LA BURBUJA MISMA. SE PUEDEN OBTENER VELOCIDADES DE LA PRODUCCION DE PELICULA MEJORADAS.
