Abstract:
A roll coater with a recirculation loop is disclosed. Waste coating material form the roll coater is treated in an agitator unit containing, for example, one or more ultrasonic transducers, and optionally a filtration unit and/or temperature control unit to produce reconditioned coating solution, such as a reconditioned sol-gel precursor solution. Also disclosed is preventative maintenance module comprising a cleaning unit that is designed to engage and clean the applicator and/or metering rolls in a roll coater.
Abstract:
PROBLEM TO BE SOLVED: To provide a coating device and an inkjet recording apparatus, which can stably coat process liquid in a good condition.SOLUTION: In the coating device configured to draw up process liquid reserved in a process liquid vessel 306 by a drawing-up roller 304 to supply the process liquid to a coating roller 302, the inside of the process liquid vessel 306 is divided into a reservoir 306A and a recovery chamber 306B by a partition plate 308, and the process liquid is circulated and supplied to always overflow to the recovery chamber 306B side. Thereby, the liquid level thereof can be always maintained constant, and the process liquid can be stably coated. In addition, since the process liquid is circulated and supplied, the liquid concentration and the liquid temperature can be easily controlled.
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus for coating a functional membrane that makes a total thickness of an active material layer and the functional membrane uniform after coating the functional membrane without depending on the thickness deviation of the active material layer before being coated with the functional membrane. SOLUTION: The apparatus coats the functional membrane on a current collector with the active material layer thereon. The apparatus includes: first and second rolls for advancing the current collector; a gravure roll configured to coat the functional membrane on the active material layer; a thickness measurer configured to measure at least one of a total thickness of the active material layer and the functional membrane and a thickness of the active material layer; and a controller connected to the thickness measurer and configured to control a rotation speed of the gravure roll.
