Color color coated steel plate cold-rolled substrate produced by cold-rolled substrate, with a smooth beautiful appearance, and has the processing performance of cold-rolled sheet; but will put any small scratches the surface coating of cold-rolled substrate is exposed to air Lottery coated plate, so that the dew point quickly generate red iron rust. Therefore, these products can only be used for temporary quarantine measures and less demanding for interior timber. Caitu Roller knowledge: Use a roller coater device, through the transfer of paint to take a different way to get the paint color coated leveling arrangement Which is good, and eventually transferred to the uniform movement of the strip and then cured color coated board manufacturers, thereby solid organic polymer layer protective film coating methods in the strip surface. 2. roll coating equipment 2.1 painted head: used to make coated steel front caitu wholesale equipment modules, including transmission equipment, coating roller, belt roller, uniform paint roller (three-coat when used); 2.2 Under the painted head: on the back of the strip used for coating equipment modules, including transmission equipment, coating roller, belt feed roller. 2.3 support rollers: play a supportive role, the strip does not vibrate when the coating, and the position of the strip with the coating roller contacts remain flat and there is a certain amount of overlap. 2.4 uniform paint roller: or call metering roller, with the strip by pressing the coating roll of the roll surface to obtain a desired thickness of wet material, arrangement and homogenized. General use hard chrome plating or anilox rolls. Extrusion coating method divided positive gap extrusion (uniform paint roller and feed rollers with no overlap part) and a negative gap extrusion (uniform with paint roller and feed rollers overlap part). 2.5 with roller: brought up from the tray and paint roller and transferred to the coating. Also play a role in both uniform paint roller roll reverse coating mode. Depending on the application method can be used with hard chrome plated rolls, anilox roller or rubber. 2.6 a coating roll: The extrusion coating uniformly transferred (applied) onto the strip. Use rubber roller. Caitu that Cheap, Jinhong Run steel (certified), Shunyi District caitu provided by Boxing Xingfu Town 金宏润 Steel Industry and Trade Ministry.
