著色后的鋁卷產品不但可以保持板材本身的性能，而且還具備更好的美觀性與裝飾性能，因此應用也是非常廣泛的，不過并不是所有的著色工藝都能得到理想的效果，有時候也會出現色淺的問題，為什么會這樣呢？下面鋁卷生產廠家來為大家分析一下吧。
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、染液溫度或濃度不均。引入攪拌工藝，同時增加攪拌的次數。
1. The temperature or concentration of dye solution is uneven. The mixing process is introduced and the mixing times are increased.
2、染液溫度太低。可給染液加溫至60℃左右。
2. The temperature of dye solution is too low. The dye solution can be heated to about 60 ℃.
3、導電不良。可能掛具松動造成的，只要注意掛緊就可避免此類問題。
3. Poor conductivity. It may be caused by loose slings, and such problems can be avoided by paying attention to fastening.
4、染料溶解不當或有不溶染料飄浮，此時易產生色差。解決的辦法是改進染料溶解。
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、鋁卷的氧化皮膜厚度不均。可能原因是陽極氧化槽液溫度、濃度不均，這時應對槽液進行壓縮空氣攪拌，以解決此類問題。
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、染色速度過快。工件底部入染液中而離開染液，因此底部易染深。解決的辦法是調稀染料，適當延長染色時間。
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，提高濃度。
7. If the dye is too thin, add dye to increase the concentration.
