溶液流延方法和沉积物移除装置
摘要：
鼓清洁装置(65)具有喷嘴(66)。所述鼓清洁装置(65)被设置在剥离辊(34)的上游。通过使用流延模(30)，将涂料(21)流延到所述流延鼓(32)的表面上。使所述流延鼓(32)旋转，以在所述表面上形成流延膜(33)。通过所述流延鼓(32)冷却所述流延膜(33)。含有作为主要组分的脂肪酸酯的沉积物从所述流延膜(33)沉淀到所述表面上。剥离辊(34)剥离所述流延膜(33)作为湿膜(38)。所述鼓清洁装置(65)将含有空气和干冰粒子的气体混合物从所述喷嘴(66)吹送到所述表面上。
摘要（英）：

A drum cleaning device (65) has a nozzle (66) . The drum cleaning device (65) is disposed in the upstream from a peel roller (34) . A dope (21) is cast onto a surface of the casting drum(32) by using a casting die (30) . The casting drum(32) is rotated to form a casting film(33) on the surface. The casting film(33) is cooled by the casting drum(32) . Deposits containing fatty acid ester as a maincomponent are precipitated from the casting film(33) onto the surface. The peel roller (34) peels off the casting film(33) as a wet film(38) . The drum cleaning device (65) blasts gas mixture containing air and dry ice particles from the nozzle (66) onto the surface.
