着色后的铝卷产品不但可以保持板材本身的性能，而且还具备更好的美观性与装饰性能，因此应用也是非常广泛的，不过并不是所有的着色工艺都能得到理想的效果，有时候也会出现色浅的问题，为什么会这样呢？下面铝卷生产厂家来为大家分析一下吧。
Colored aluminum coil products can not only maintain the excellent performance of the plate itself, but also have better aesthetic and decorative properties, so they are also widely used. However, not all coloring processes can achieve ideal results, and sometimes the problem of light color occurs. Why is this so? Next, the aluminum coil manufacturer will analyze it for you.
1、染液温度或浓度不均。引入搅拌工艺，同时增加搅拌的次数。
1. The temperature or concentration of dye solution is uneven. The mixing process is introduced and the mixing times are increased.
2、染液温度太低。可给染液加温至60℃左右。
2. The temperature of dye solution is too low. The dye solution can be heated to about 60 ℃.
3、导电不良。可能挂具松动造成的，只要注意挂紧就可避免此类问题。
3. Poor conductivity. It may be caused by loose slings, and such problems can be avoided by paying attention to fastening.
4、染料溶解不当或有不溶染料飘浮，此时易产生色差。解决的办法是改进染料溶解。
4. If the dye is not dissolved properly or there is insoluble dye floating, color difference may occur. The solution is to improve the dye dissolution.
5、铝卷的氧化皮膜厚度不均。可能原因是阳极氧化槽液温度、浓度不均，这时应对槽液进行压缩空气搅拌，以解决此类问题。
5. The oxide film thickness of aluminum coil is uneven. The possible reason is that the temperature and concentration of anodizing bath solution are uneven. At this time, the bath solution should be stirred with compressed air to solve this problem.

6、染色速度过快。工件底部入染液中而离开染液，因此底部易染深。解决的办法是调稀染料，适当延长染色时间。
6. The dyeing speed is too fast. The bottom of the workpiece enters the dye solution first and leaves the dye solution, so the bottom is easy to dye deeply. The solution is to dilute the dye and extend the dyeing time appropriately.
7、染料太稀，可添加染料，提高浓度。
7. If the dye is too thin, add dye to increase the concentration.
