是什么原因导致铝板氧化膜颜色不均匀?具体包括以下三个方面:
　　What causes the uneven color of the oxide film on the aluminum plate? Specifically, it includes the following three aspects:
　　(1)铝板工件面积过大，在使用过程中槽内摆动过大，边缘与中心部位及溶液接触、更新、交换差异太大，导致氧化膜颜色不一致。预防方法:工件摆动幅值在铝板氧化很小时，静置处理也可以，但当溶液温度过低时容易出现像地图一样的斑点，显得不自然。
　　(1) the area of the aluminum plate workpiece is too large, the swing in the groove is too large during the use process, and the difference between the edge and the center part and the solution contact, renewal and exchange is too large, resulting in the inconsistent color of the oxide film. Prevention method: when the swing amplitude of workpiece is very small in the oxidation of aluminum plate, the static treatment can also be done, but when the solution temperature is too low, it is easy to appear spots like a map, which is not natural.

　　(2)铝复合板在加工过程中，部分铝涂层被破坏和切断，外层为优质铝，内层为杂铝。这两种铝之间的差异很大，所以氧化后，有“白癜风”般的斑点。这一现象客户往往也不会理解，厂家要多做说明工作，说明原因，以免引起误解。
　　(2) in the process of processing, part of the aluminum coating is damaged and cut off, the outer layer is high-quality aluminum, and the inner layer is miscellaneous aluminum. There is a big difference between the two kinds of aluminum, so there are spots like "vitiligo" after oxidation. This phenomenon is often not understood by customers. Manufacturers should do more explanation work and explain the reasons to avoid misunderstanding.
　　(3)铝板氧化工艺操作中存在的问题
　　(3) problems in the operation of aluminum plate oxidation process(1)工件碱腐蚀处理不彻底，局部原有氧化膜，污垢未能清除;(2)碱腐蚀后没有立即进行光处理，工件表面仍是碱性的;(3)工件在传动过程中与外界物质接触。
　　(1) the alkali corrosion treatment of the workpiece is not complete, and the original oxide film and dirt are not removed; (2) the surface of the workpiece is still alkaline without immediate light treatment after alkali corrosion; (3) the workpiece contacts with external substances during the transmission process.
　　当出现胶片颜色不均时，要从多方面寻找原因，有针对性地采取措施解决。
　　When the color of the film is uneven, we should find out the reasons from many aspects and take measures to solve them.
　　向每个人解释的基本原则,导致颜色的氧化膜铝板不均匀,相信铝板厂家的技术人员有一个完整的概念,只要将这三个独特的战术,电影的问题,颜色氧化铝板不均匀将迎刃而解。
　　The basic principles explained to everyone lead to the uneven color of aluminum oxide film. I believe that the technicians of aluminum plate manufacturers have a complete concept. As long as these three unique tactics, film problems and the uneven color of aluminum oxide plate are solved.
