Title
(EN) Manufacturing method of polymer film
(ZH) 聚合物膜的制备方法
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.

由共流延形成具有基层和一层外层的流延膜(80)。外层涂料的粘度至多为40Pa·s。刚好在形成流延膜(80)之后,将干燥空气从出口(82a)开口到供应到皮带(73)。温度和静压力分别为预定值50-160℃和50-200Pa。由分隔构件分隔出第一出口,并且将筛板附着到面对流延膜(80)两侧边缘部分的隔间。将另一干燥空气从在皮带(73)运行方向上的出口(83a)供出。温度和风速分别为预定值50-160℃和5-20m/s。减少了不均匀性和起泡的发生,并且制备出具有优异平面度的膜。
