铝板是生活中常见的材料，已经在各行各业中使用，除了常见的原色，铝板也可以加工成色彩，以达到视觉装饰的追求。但是在加工的过程中往往会出现无法着色的问题，为什么会出现这种情况呢?下面为大家分享一下铝板生产厂家出现这种情况的原因和解决方案。
Aluminum plate is a common material in life and has been used in all walks of life. In addition to the common primary color, aluminum plate can also be processed into color to achieve the pursuit of visual decoration. However, in the process of processing, there is often the problem of unable to color. Why does this happen? Let's share the causes and solutions of this situation for aluminum plate manufacturers.
1. 染料已溶解或发霉:此时需要将染料去除更换，使用合适的染料。
1. The dye has been dissolved or moldy: at this time, it is necessary to remove and replace the dye and use appropriate dye.
2、导电性差:阳极铜棒或负铅板松动，导致导电性差。定期清洗阳极铜棒和负铅板，可保证导电性能。
2. Loose anode or poor conductivity of copper plate. Regular cleaning of anode copper bar and negative lead plate can ensure conductivity.
3、膜厚不够:检查是否阳极氧化过程的标准,是否温度,工作电压,电导率和其他元素是稳定的,如果有异常,可以调整恢复标准,如果没有异常,可以适当增加空气氧化时间,确保膜厚度是合格的。
3. Insufficient film thickness: check whether the standard of anodizing process, temperature, working voltage, conductivity and other elements are stable. If there is any abnormality, adjust the recovery standard. If there is no abnormality, appropriately increase the air oxidation time to ensure that the film thickness is qualified.
4. 空气氧化后，钢件在不锈钢罐中放置时间过长。在时间方面,铝板厂家认为好是选择直接染色,但如果这已经发生,可以放置在铝板阳极处理罐或氰化钠的细胞,温和的活动中和在使用染色之前,实际结果会很好。

4. After air oxidation, the steel parts are placed in the stainless steel tank for too long. In terms of time, aluminum plate manufacturers think it is best to choose direct dyeing, but if this has happened, it can be placed in aluminum plate anodizing tank or sodium cyanide cells. The actual results will be very good after mild activity and before dyeing.
5、空气氧化温度过低，导致皮膜密度过高:可适度提高空气氧化温度。
5. The air oxidation temperature is too low, resulting in too high film density: the air oxidation temperature can be moderately increased.
6、染料的ph值过高:可以用冰醋酸将ph值调整到标准值。
6. The pH value of the dye is too high: the pH value can be adjusted to the standard value with glacial acetic acid.
