Title:
FUNCTIONAL MEMBRANE MANUFACTURING METHOD, DRYER, AND FUNCTIONAL MEMBRANE MANUFACTURING APPARATUS
Document Type and Number:
Japanese Patent JP2020000954
Kind Code:
A
Abstract:
To provide a functional membrane manufacturing method by which occurrence of streak-like unevenness on a surface of a functional membrane can be suppressed, a dryer, and a functional membrane manufacturing apparatus.SOLUTION: A method for manufacturing a functional membrane provided on a top face of a long substrate has a coating process in which an ink containing a material of the functional membrane is applied thereby forming a coated film, and a drying process in which the coated film is dried while transporting the substrate. The drying process comprises a first process in which the substrate is transported by a first distance, and a temperature of the substrate is raised from a first temperature to a second temperature during transportation. In the first process, when the first distance is represented by d(m), the first temperature is represented by T(°C), and the second temperature is represented by T(°C), a relationship of the following formula is satisfied: (T-T)/d≥10 (1a), and a maximum value of an instantaneous temperature change rate of the substrate is 5°C/second or less.SELECTED DRAWING: Figure 1
