Abstract

PRODUCCION DE LAMINAS DE POLIETILENO LINEAL DE BAJA DENSIDAD (VLDPE) MEDIANTE UN PROCEDIMIENTO DE CALANDRADO CON POSTERIOR ESTIRAMIENTO SUCESIVO DEL POLIETILENO LINEAL HASTA EL ULTIMO CILINDRO DE CALANDRADO. EL POLIETILENO FUNDIDO TIENE UNA DENSIDAD DE 0,900 A 0,915 G/CM3. NO OBSTANTE A UNA TEMPERATURA POR DEBAJO DE 190 C CON PEQUEÑAS CARGAS SE CONSIGUEN EN EL ULTIMO CILINDRO DE CALANDRADO PRODUCCIONES DE LAMINAS FINALES DE 90,3 G POR HORA Y CM2 DE SECCION HASTA 135 KG POR HORA Y CM2 DE SECCION Y CON ESPESORES QUE VARIAN ENTRE 100 A 300 (MU),. SE EEXTRAE CON VELOCIDAD ELEVADA. LA REDUCCION NECESARIA PARA ALCANZAR EL ESPESOR DE LAMINA FINAL SE OBTIENE MEDIANTE MEDIDAS DEL AVANCE DEL ESTIRAMIENTO FRENTE AL ULTIMO CILINDRO DE CALANDRADO.
