我们都知道彩涂镀锌板的颜色是多种多样的。彩涂镀锌板的着色问题及色差控制是生产厂家需要解决的问题，也是保证产品质量的关键。基体上不同尺寸的锌花在晶界形成许多不同尺寸的小凹坑，影响板表面的色差，特别是光色。最好选用无锌或小锌基基材。

如何控制 彩涂镀锌板的色差？我们用天然气为生产设备提供炉温。所以烤箱的温度是平衡的，不会有时间间隔的温差，生产前必须对油漆进行均匀的调整。

薄膜厚度的稳定性对彩色涂层板的色差有很大的影响。首先，涂膜厚度的调整包括：涂膜粘度、胶辊与涂膜辊的间隙、涂膜辊与胶辊速度的变化、涂膜辊与支撑辊压力的调整。

至于 彩涂镀锌板的操作，渗漏的原因是基材有游动、变形、氧化等因素。当然，控制色差是保证产品质量的关键因素，因此必须引起每一个工人的重视，才能更有效地保证该产品的可用性。

由于涂料混合不均匀或不同桶内涂料粘度高，涂料从进料口侧向料盘回流口方向延伸，呈现色差带。另外，油漆颜色的变化，特比在颜色上反差很大，因为清洗不干净，污染形成色差。

通过以上内容，我们可以看出彩涂板色差问题是正常的，也是不可避免的。因此，建议用户尽量一次性购买所有色差。同批生产的彩涂板色差问题可能比较小。
We all know that the colour of colour-coated galvanized sheet is various. The colouring problem and how to control the colour difference of colour-coated galvanized sheet are the problems that our manufacturers need to overcome and the key to ensure the quality of products.
The different sizes of zinc flower on the substrate make up many small pits of different sizes at the grain boundary, which have an effect on the color difference of the surface of the board, especially on the light color. It is better to choose zinc-free or small zinc-based substrate.
How to control the color difference of color coated galvanized sheet? We use natural gas to supply the oven temperature for the production equipment. So the oven temperature is balanced, there will be no time interval temperature difference, and the paint must be adjusted uniformly before production.

The stability of film thickness has a great influence on the chromatic aberration of color coated panels. Firstly, the adjustment of film thickness includes: the coating viscosity, the gap between the adhesive roll and the coating roll, the change of the speed of the coating roll and the adhesive roll, and the adjustment of the pressure between the coating roll and the strip support roll.

As for the operation of color-coated galvanized sheet, the reason for the leakage is that the substrate has swimming, deformation, oxidation and other factors. Of course, controlling the color difference is the key factor to ensure the quality of products, so we must draw the attention of every worker, so as to ensure the availability of this product more effectively.

Because of the uneven mixing of coatings or the high viscosity of coatings in different barrels, the coatings extend from the side of the feed port to the direction of the reflux port in the material tray, showing a color difference band. In addition, the change of paint color, Tebby is a big contrast in color, because the cleaning is not clean, pollution forms a color difference.

Through the above content, we can see that the color difference problem of color coated panels is normal and inevitable. Therefore, it is suggested that users should purchase all the color difference in one time as far as possible. The color difference problem of color coated panels produced in the same batch may be relatively small.
