Abstract

EN UN METODO PARA FORMAR UN TUBO T DE CELULOSA ADECUADO PARA SU USO COMO CUBIERTA DE UN ALIMENTO, EN EL QUE UNA SOLUCION DE CELULOSA NO DERIVATIZADA, OXIDO N DE AMINA TERCIARIA Y AGUA ES EXTRUIDA A TRAVES DE UNA ABERTURA TROQUELADA 18 Y EL TUBO EXTRUIDO SE EXTRAE HACIA ABAJO A TRAVES DE UNA ABERTURA DE AIRE MIENTRAS ES ENFRIADO INTERNAMENTE Y DESPUES ES PASADO A UN BAÑO DE AGUA 21, LA RESISTENCIA A LA TRACCION EN DIRECCION TRANSVERSAL AL TUBO SE INCREMENTA MEDIANTE LA EXTRACCION DEL TUBO EXTRUIDO A TRAVES DE UNA LONGITUD DE AIRE DE AL MENOS ALREDEDOR DE CINCO PULGADAS (127 MM) Y EXPONIENDO A LA SUPERFICIE EXTERIOR DEL TUBO EXTRUIDO A AIRE FRIO EN LA ABERTURA DE AIRE. EL FLUJO DE AIRE FRIO ESTA FORMADO POR UNA CORTINA DE AIRE QUE FLUYE HACIA ABAJO FORMADO POR LAS APERTURAS 62 EN UN ANILLO DE AIRE 61 CONECTADO A UN TUBO DE TORBELLINO 64 AUTOCONECTADO A UNA FUENTE DE AIRE PRESURIZADO P.
