    • The present invention refers to a drying method for drying a coating layer which is formed by coating a moving web with a coating solution containing organic solvent, comprising steps of:
      drying said web surrounded by a casing at a transporting position just after the coating with a drying device, so as to prevent disturbance of wind closed to a coating surface, said drying device having a heating means, wherein the atmosphere in or out of said casing is not fed out or sucked in said drying device;
      heating with said heating means, such that a temperature difference |T2-T1| between a temperature T1 of said coating layer at an entrance of said drying device and a temperature T2 of said coating layer at an exit of said drying device at most 5°C.
    • 本发明涉及一种干燥涂布层的干燥方法,所述涂布层是通过用包含有机溶剂的涂布液涂布移动的纸幅而形成的,所述方法包括以下步骤:在涂布后立即在输送位置干燥由壳体围绕的所述纸幅 所述干燥装置具有加热装置,其中所述外壳内的气氛不被送出或吸入到所述干燥装置中; 用所述加热装置加热,使得温度差| T2-T1 | 在所述干燥装置的入口处的所述涂层的温度T1与所述干燥装置的出口处的所述涂层的温度T2之间至多5℃。

    • The present invention relates to a drying method for drying a coating layer which is formed by coating a moving web with a coating solution containing organic solvent, comprising steps of transporting almost vertically and upward said web immediately after the coating, inclining with one or larger number of guide roller the upward transporting of said web from an almost vertical direction toward a horizontal direction gradually, drying said coating layer with a drying device having a casing which surrounds said web just after the coating while disturbance of wind close to a coating surface is prevented, and concentration of said solvent vapor in a side of a surface of said coating layer is kept high, during said drying, condensing said solvent vapor by at least one device for condensing and recovering said solvent, said at least one condenser being arranged such that a condensing surface of said at least one condenser faces a surface of said coating layer, said device including protrusions and grooves formed on said condensing surface, and a gutter; and recovering the condensed vapor of said solvent by said gutter of said at least one device.
    • 本发明涉及通过用含有机溶剂的涂布溶液涂布移动幅材而形成的涂层干燥方法,其特征在于,包括以下步骤:在涂布后立即将所述纸幅垂直地向上运送,并以一个或多个数字倾斜 引导辊将所述幅材从几乎垂直的方向向上运送到水平方向上,用干燥装置干燥所述涂层,所述干燥装置具有刚刚涂覆之后围绕所述纸幅的壳体,同时阻止接近涂层表面的风的扰动 并且所述溶剂蒸气在所述涂层的表面侧的浓度保持较高,在所述干燥期间,通过至少一个用于冷凝和回收所述溶剂的装置冷凝所述溶剂蒸气,所述至少一个冷凝器被布置成使得 所述至少一个冷凝器的冷凝表面面向所述涂层的表面,所述装置包括突出部 形成在所述冷凝表面上的离子和沟槽,以及沟槽; 以及通过所述至少一个装置的所述槽回收所述溶剂的冷凝蒸气。
