We all know that the color of color coated galvanized sheet is diverse. The color problem and how to control the color difference of color coated galvanized sheet are the problems that our manufacturers need to overcome and the key to ensure the quality of products.

　　基板锌花大小的不一样，在晶界处便构成很多大小不一的小凹坑，对板面色差形成影响，对淡色彩尤为显着。选用无锌花或小锌花基板。

　　Different sizes of zinc flowers on the substrate form many small pits of different sizes at the grain boundary, which have an impact on the formation of color difference on the surface of the board, especially on the light color. It is better to choose the substrate without zinc flower or small zinc flower.

　　怎么控制彩涂镀锌板色差问题，咱们出产设备使用天然气供烘箱温度，这么烘箱温度是均衡的，不会出现时间段温差，以及出产之前油漆一定要调均匀。

　　How to control the color difference of color coated galvanized sheet? We use natural gas to supply the oven temperature for our production equipment, so that the oven temperature is balanced, there will be no temperature difference in time period, and the paint must be evenly adjusted before production.

　　膜厚稳定性对彩涂板色差的影响较大。膜厚的调整首要经过：涂料粘度、调整辊涂机粘料辊与涂敷辊之间的缝隙、改变涂敷辊和粘料辊的辊速、调整涂敷辊与带钢支持辊之间的压力。

　　The stability of film thickness has great influence on the color difference of color coated plate. The adjustment of film thickness mainly includes: coating viscosity, adjusting the gap between the sticking roller and the coating roller, changing the roller speed of the coating roller and the sticking roller, adjusting the pressure between the coating roller and the strip support roller.

　　关于操控彩涂镀锌板漏涂，漏涂是因为基板有游、变形、氧化等因素形成的。当然，控制好色差是保证产品质量的关键性因素，所以一定要引起每位做业人员注意，从而来更有效的保证该款产品的可用性。

　　As for the missing coating of color coated galvanized sheet, the missing coating is caused by the factors such as floating, deformation and oxidation of the base plate. Of course, controlling the color difference is the key factor to ensure the quality of the product, so we must pay attention to it, so as to ensure the availability of the product more effectively.

　　彩涂板由于涂料搅拌不均匀或者不一样桶的涂料黏度产别大，涂料在料盘中从进料口一侧向回流口方向延伸，呈现色差带。另外更换涂料色彩，特比是色彩反差较大的，由于清洗不干净，污染形成色差。

　　Due to the uneven mixing of the coating or the high viscosity of the coating in different barrels, the coating extends from one side of the feed port to the reflux port in the material tray, showing a color difference band. In addition, to change the color of the paint, especially the color contrast is large, because the cleaning is not clean, pollution forms color difference.
