Abstract

PROCEDIMIENTO DE FABRICACION DE UNA PELICULA DE POLI(ALCOHOL VINILICO).CONSISTE EN LA FABRICACION DE UNA PELICULA DE POLI(ALCOHOL VINILICO) QUE SE REALIZA EN VARIAS ETAPAS: A) LA MATERIA FUNDIDA SOMETIDA A EXTRUSION SE OBTIENE POR PLASTIFICACION POR CIZALLAMIENTO Y FUSION DE GRANULOS DE POLI(ALCOHOL VINILICO). LOS GRANULOS TIENEN DE 25 A 35 EN PESO DE AGUA A TEMPERATURA SUPERIOR A LA DE FUSION DE EQUILIBRIO DE LA MEZCLA; B) LA OPERACION DE EXTRUSION SE EFECTUA A TEMPERATURA IGUAL A LA DE FUSION DE EQUILIBRIO DE LA MEZCLA DE POLI(ALCOHOL VINILICO)-AGUA, PERO INFERIOR A AQUELLAEN LA QUE LA TENSION DE VAPOR DEL AGUA ES SUFICIENTE PARA PROVOCAR EN EL AIRE LA FORMACION DE BURBUJAS. LA TEMPERATURA DE PLASTIFICACION Y FUSION DE LOS GRANULOS ES ENTRE 150 Y 220JC. LA TEMPERATURA DE EXTRUSION ESTA COMPRENDIDA ENTRE 5 GRADOS POR ENCIMA DE LA TEMPERATURA DE FUSION DE EQUILIBRIO Y 98JC. DESPUES DE LA EXTRUSION A TRAVES DE LA HILERA PLANA, LA PELICULA SIN ALARGAR SE SOMETE A UNA OPERACION DE ALARGAMIENTOLONGITUDINAL A UNA TEMPERATURA DE 100 A 130JC HASTA UN GRADO DE ALARGAMIENTO DE 2 A 5.
