Title:
MANUFACTURING METHOD FOR FUNCTIONAL MEMBRANE, DRYING DEVICE, AND MANUFACTURING DEVICE FOR FUNCTIONAL MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2020/003678
Kind Code:
A1
Abstract:
A manufacturing method for manufacturing a functional membrane provided on the top face of an elongated substrate, said method having a coating step for forming a coating membrane by coating the top face of the substrate with ink containing the functional membrane material and a drying step for drying the coating membrane while transporting the substrate. The drying step comprises a first step of transporting the substrate a first distance and increasing, during this time, the temperature of the substrate from a first temperature to a second temperature. In the first step, the following relationship is satisfied: (T2 − T1)/d1 ≥ 10 (1a), where d1 (m) is the first distance, T1 (°C) is the first temperature, and T2 (°C) is the second temperature, and the maximum value of the instantaneous rate of temperature change of the substrate is 5°C/minute or less.
