METHOD FOR COATING DEEPLY ENGRAVED BUILDING MATERIAL

摘要

PURPOSE:To allow the execution of applying =2 colors on a deeply engraved building material by line coating while improving the yield of a coating material. CONSTITUTION:This method consists in applying the coating materials of different coating colors on the building material 1 formed with rugged patters by deep engraving on the surface by applying these coating materials on the surface of the building material by coating means 2, 3, such as flow coaters, while transporting the building material 1 in one direction, then blowing off the coating materials by an air nozzle 4 on the downstream side of the coating position. The one coating material is applied in the coated amt. of =1.4 times the coated amt. of the other coating material. The air is blown by the air pressure of the extent to fluidize the coating material on the side of the smaller coated amt. on the surface of the building material in the state of inclining the above- mentioned air nozzle 4 toward the downstream side on the coated surface side of the larger coated amt. within an angle theta1 range of 20 to 30 deg..
