Trennmittel-Flüssigkeitsdosierungsvorrichtung und flüssigkeitsabsorbierendes Material dafür

摘要

The present invention is directed to a liquid metering and coating device comprising a perforated hollow member (1); a liquid-absorbent porous material (5) within said hollow member (1); at least one shaft component (6,7) which seals the liquid-absorbent porous material (5) within the hollow member (1), a means (8) for air passage; a liquid diffusion layer (3) in contact with the perimeter of the perforated hollow member (1); and a liquid permeation regulating layer (4) in contact with the perimeter of the liquid diffusion layer (3). The liquid metering and coating device can satisfactorily apply a liquid to a surface with exceptional accuracy, uniformity and durability.
