鋁卷是我們的主要產(chǎn)品之一，作為一家生產(chǎn)鋁卷的廠家，我們擁有的生產(chǎn)技術(shù)，對(duì)鋁卷有深刻的了解。
　　Aluminum coil is one of our main products. As a professional manufacturer of aluminium coil, we have advanced production technology and profound knowledge of aluminium coil.
　　1. 預(yù)處理:對(duì)鋁卷表面進(jìn)行物理和化學(xué)清洗，其中重要的是將鋁卷暴露在基體上。
　　1. Pretreatment: physical and chemical cleaning of the surface of aluminium coil, the most important of which is to expose the aluminium coil to the matrix.
　　2. 陽(yáng)極氧化后，經(jīng)鋁卷處理后，基體發(fā)生陽(yáng)極氧化反應(yīng)，形成致密的氧化膜。
　　2. After anodic oxidation, the matrix undergoes anodic oxidation reaction after aluminium coil treatment, forming a dense oxide film.
　　3孔密封，陽(yáng)極氧化后，氧化膜會(huì)出現(xiàn)很多孔，孔密封是為了使膜孔閉合，防止氧化膜污染。氧化膜是透明的，但也有吸附作用，這就會(huì)在一些孔內(nèi)沉積金屬鹽，所以它可以在外表上顯示出一些原本銀白色的，或者外表很多顏色。這是整個(gè)鋁卷板上色的步驟，在加工過(guò)程中，我們需要注意鋁板的變化
　　3-hole seal, after anodic oxidation, there will be many holes in the oxide film. The purpose of the hole seal is to make the film hole closed and prevent the oxide film pollution. The oxide film is transparent, but also has adsorption, which deposits metal salts in some holes, so it can show some original silver white on the surface, or many colors on the surface. This is the process of colouring the whole aluminium coil sheet. In the process of processing, we need to pay attention to the change of the aluminium sheet.

　　由于鋁卷可被氧化生成致密的氧化鋁膜，且與鋁不斷反應(yīng)，所以，鋁卷白斑應(yīng)是正常現(xiàn)象。
　　Because aluminium coil can be oxidized to form dense alumina film and react with aluminium continuously, the white spot of aluminium coil should be a normal phenomenon.
　　但是，由于鋁盤(pán)管板表面要求嚴(yán)格，如何避免鋁盤(pán)管表面出現(xiàn)白點(diǎn)，使產(chǎn)品光潔度和亮度更好，這不僅與加工工藝有關(guān)，而且與后期的表面處理工藝密切相關(guān)。
　　However, due to the strict surface requirements of the aluminium coil plate, how to avoid the appearance of white spots on the surface of the aluminium coil plate to make the product smoother and brighter is not only related to the processing technology, but also closely related to the later surface treatment process.

　　在大型鋁卷合金產(chǎn)品的陽(yáng)極氧化過(guò)程中，發(fā)現(xiàn)加工完成后表面會(huì)出現(xiàn)白點(diǎn)，尤其是氧化鋁卷。在這里，我們將分析這一現(xiàn)象的原因。
　　In the process of anodic oxidation of large aluminium coil alloy products, it was found that white spots appeared on the surface after processing, especially alumina coil. Here, we will analyze the reasons for this phenomenon.
　　其實(shí)主要原因很簡(jiǎn)單:鋁盤(pán)管氧化后未徹底清洗，導(dǎo)致表面干燥后產(chǎn)生白斑，解決辦法是加強(qiáng)氧化后的清洗，盡量用水槍徹底清洗。同時(shí)，清洗后，注意保護(hù)表面，盡量讓產(chǎn)品不與其他產(chǎn)品接觸，自然風(fēng)干。
　　Actually, the main reason is very simple: the aluminium coil is not cleaned thoroughly after oxidation, resulting in white spots on the surface after drying. The solution is to strengthen the cleaning after oxidation and try to clean thoroughly with water gun. At the same time, after cleaning, pay attention to protecting the surface, try not to contact with other products, natural air-drying.
　　也希望更好地控制白斑表面的鋁卷板不僅應(yīng)該注意產(chǎn)品表面前處理問(wèn)題,同時(shí)還應(yīng)注意防止表面處理加工,加工過(guò)程和加工過(guò)程的標(biāo)準(zhǔn)嚴(yán)格避免白點(diǎn)的形成。堿洗干凈的白點(diǎn)酸洗很好，但要控制濃度，否則噴漆，堵塞鋁與氧氣的接觸。
　　It is also hoped that better control of white spot surface of aluminium coiled sheets should not only pay attention to the surface pretreatment of products, but also pay attention to preventing surface treatment processing, processing and processing standards to strictly avoid the formation of white spots. Alkali clean white spot pickling is good, but the concentration should be controlled, otherwise spray paint, blocking the contact between aluminum and oxygen.
