现在铝板在我们日常生活中很常见，而且铝板有很多的类型，铝板在生产过程中会出现一些黑斑，那么会导致铝板表面上怎么会出现黑斑?这些黑斑是无法去掉的，下面铝板生产厂家给大家讲解一下。
Now aluminum plate is very common in our daily life, and there are many types of aluminum plate. There will be some black spots on the surface of aluminum plate in the production process, so how can there be black spots on the surface of aluminum plate? These black spots cannot be removed. The aluminum plate manufacturer will explain them to you.
现在的铝板有不同种类，但是这些铝板的材料，在加工的时候，零件如果没有出现黑斑的状况，这不是原材料的缺陷而导致的故障，导致铝板加工出现黑斑的故障的原因是硫元素对镀银层的影响。
Now there are different types of aluminum plates, but if there are no black spots on the parts during processing, it is not caused by the defects of raw materials. The reason for the black spots in aluminum plate processing is the effect of sulfur on the silver coating.
铝板在喷漆工艺方面，发现喷漆加工，出现整批返修的纪录，原因就是缺口未堵上，在表面没法清除，为防止此类故障的发生，缺口封死，零件未及时包装并密封保存，久置在电镀厂房中而导致镀银层变黄。
In terms of the painting process of aluminum plate, it was found that the whole batch of repair records were found in the painting process, because the gap was not blocked and could not be removed on the surface. In order to prevent the occurrence of such failures, the gap was sealed, the parts were not packaged and sealed in time, and the silver plating layer turned yellow after being left in the electroplating workshop for a long time.
故障零件在镀银后，及时包装并置于干燥器皿中保存，这并不是受到厂房空气气氛的影响，在生产条件的情况下，同期加工的类似零件没有出现故障，所以排除了电镀生产条件发生改变的因素。
After silvering, the faulty parts are packed in time and stored in dry containers. This is not affected by the air atmosphere in the workshop. Under the production conditions, similar parts processed at the same time do not have faults, so the factors that affect the electroplating production conditions are eliminated.

加工过程的表面处理工艺中使用了强腐蚀性的清洗剂，对铝的基体造成了腐蚀现象，从而导致铝材发黑。
In the surface treatment process of the processing process, a strong corrosive cleaning agent is used, which causes corrosion to the aluminum substrate, resulting in the blackening of the aluminum material.
存放环境温度与湿度较高，铝的性质活泼，在这种环境中铝会产生氧化，并形成一层暗色的氧化膜。
The storage environment is high in temperature and humidity, and the nature of aluminum is active. In this environment, aluminum will oxidize and form a dark oxide film.
经过压铸、机械加工后，使用清洗剂未能清洗干净，表面长时间存在残留物，出现霉斑。
After die casting and machining, the cleaning agent was not used to clean the surface, leaving residue and mildew on the surface for a long time.
处理工艺不合理，在使用清洗剂清洗、抛光等表面处理后，未能及时进行防氧化，或者钝化处理，导致铝合金发生腐蚀、氧化。
The treatment process is unreasonable. After surface treatment such as cleaning and polishing with cleaning agent, the oxidation prevention or passivation treatment is not carried out in time, resulting in corrosion and oxidation of aluminum alloy.
以上就是小编给大家讲解的铝板表面上怎么会出现黑斑全部内容，相信对大家都有了一定的了解，希望可以帮助大家，铝板在加工时会出现黑斑的故障的原因就是硫元素对镀银层的影响。您有什么疑惑可以随时来咨询我们//www.renttoplux.com！
