Title
(EN) METHOD FOR PRODUCING POLYMER FILM
(FR) PROCEDE DE PRODUCTION D'UNE PELLICULE POLYMERE
Abstract
(EN)
A casting film (80) having a base layer and one outer layer are formed by co-casting. Viscosity of outer layer dope was at most 40 Pa*s. Just after formation of the casting film (80), the drying air is fed out from an outlet (82a) opening to a belt (73) . The temperature and the static pressure are respectively predetermined valued 50 - 160 degrees Celsius and 50 - 200 Pa. The first outlet is partitioned by partitioning members, and meshed plates are attached to the partitions confronting to both side edge portions of the casting film (80) . Another drying air is fed out from an outlet (83a) in a running direction of the belt (73) . The temperature and the wind speed are respectively predetermined valued 50 - 160 degrees Celsius and 5 - 20 m/s. The occurrence of unevenness and foaming is reduced and a film excellent in planarity is produced.
(FR)
L’invention concerne une pellicule coulée (80) possédant une couche de base et une couche externe, formée par co-coulage. La viscosité de l'additif de la couche externe est au moins de 40 Pa*s. Immédiatement après la formation de la pellicule coulée (80), de l'air de séchage est introduit par un orifice (82a) s'ouvrant sur une courroie (73). La température et la pression statique ont des valeurs prédéterminées allant respectivement de 50 à 160 degrés Celsius et de 50 à 200 Pa. Ce premier orifice est divisé par des éléments de partition, et des plaques grillagées sont fixées aux partitions faisant face aux deux parties latérales de la pellicule coulée (80). Un autre jet d'air de séchage est libéré par un second orifice (83a) dans le sens de marche de la courroie (73). La température et la vitesse du vent ont des valeurs prédéterminées allant respectivement de 50 à 160 degrés Celsius et de 5 à 20 m/s. On réduit le risque d'apparition de défauts de planéité et le moussagee et on obtient un film excellent en termes de planarité.
