PARTITION PLATE USED FOR COATER PAN AND ROLL COATER COATING DEVICE

摘要

PROBLEM TO BE SOLVED: To efficiently remove the air bubbles intruded into a coating material by forming network-like aperture of a specific range in the opening size of the meshes used for a coater pan contg. the coating material for applying coating on a metallic sheet by a coater roll. SOLUTION: The coating material from which the air bubbles are removed is supplied from a coating material discharge port 13a disposed near the bottom of a coating material prepn. tank 1 through coating material piping 13 to the coater pan 2 which is provided with a partition plate 80 so as to hold a pickup roll 15 partly immersed into the coating material in the coater pan 2. The partition plate 80 is formed of a high-molecular resin partition plate having a network-like apertures of 150 to 2000μm in the opening size of the meshes. The upper part thereof and both side parts thereof are reinforced with SUS plates 81. As a result, the air bubbles in the coating material are trapped and ruptured by the network part when the coating material passes the network-like aperture of the partition plate 80. The air bubbles intruded into the coating material are thus efficiently defoamed.
