是什么原因?qū)е落X板氧化膜顏色不均勻?具體包括以下三個方面:
　　What causes the uneven color of the oxide film on the aluminum plate? Specifically, it includes the following three aspects:
　　(1)鋁板工件面積過大，在使用過程中槽內(nèi)擺動過大，邊緣與中心部位及溶液接觸、更新、交換差異太大，導(dǎo)致氧化膜顏色不一致。預(yù)防方法:工件擺動幅值在鋁板氧化很小時，靜置處理也可以，但當(dāng)溶液溫度過低時容易出現(xiàn)像地圖一樣的斑點(diǎn)，顯得不自然。
　　(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)鋁復(fù)合板在加工過程中，部分鋁涂層被破壞和切斷，外層為優(yōu)質(zhì)鋁，內(nèi)層為雜鋁。這兩種鋁之間的差異很大，所以氧化后，有“白癜風(fēng)”般的斑點(diǎn)。這一現(xiàn)象客戶往往也不會理解，廠家要多做說明工作，說明原因，以免引起誤解。
　　(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)鋁板氧化工藝操作中存在的問題
　　(3) problems in the operation of aluminum plate oxidation process(1)工件堿腐蝕處理不徹底，局部原有氧化膜，污垢未能清除;(2)堿腐蝕后沒有立即進(jìn)行光處理，工件表面仍是堿性的;(3)工件在傳動過程中與外界物質(zhì)接觸。
　　(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.
　　當(dāng)出現(xiàn)膠片顏色不均時，要從多方面尋找原因，有針對性地采取措施解決。
　　When the color of the film is uneven, we should find out the reasons from many aspects and take measures to solve them.
　　向每個人解釋的基本原則,導(dǎo)致顏色的氧化膜鋁板不均勻,相信鋁板廠家的技術(shù)人員有一個完整的概念,只要將這三個獨(dú)特的戰(zhàn)術(shù),電影的問題,顏色氧化鋁板不均勻?qū)⒂卸狻?br /> 　　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.
