铝卷是我们的主要产品之一，作为一家生产铝卷的厂家，我们拥有的生产技术，对铝卷有深刻的了解。
　　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. 预处理:对铝卷表面进行物理和化学清洗，其中重要的是将铝卷暴露在基体上。
　　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. 阳极氧化后，经铝卷处理后，基体发生阳极氧化反应，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，阳极氧化后，氧化膜会出现很多孔，孔密封是为了使膜孔闭合，防止氧化膜污染。氧化膜是透明的，但也有吸附作用，这就会在一些孔内沉积金属盐，所以它可以在外表上显示出一些原本银白色的，或者外表很多颜色。这是整个铝卷板上色的步骤，在加工过程中，我们需要注意铝板的变化
　　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.

　　由于铝卷可被氧化生成致密的氧化铝膜，且与铝不断反应，所以，铝卷白斑应是正常现象。
　　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，由于铝盘管板表面要求严格，如何避免铝盘管表面出现白点，使产品光洁度和亮度更好，这不仅与加工工艺有关，而且与后期的表面处理工艺密切相关。
　　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.

　　在大型铝卷合金产品的阳极氧化过程中，发现加工完成后表面会出现白点，尤其是氧化铝卷。在这里，我们将分析这一现象的原因。
　　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.
　　其实主要原因很简单:铝盘管氧化后未彻底清洗，导致表面干燥后产生白斑，解决办法是加强氧化后的清洗，尽量用水枪彻底清洗。同时，清洗后，注意保护表面，尽量让产品不与其他产品接触，自然风干。
　　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铝卷板不仅应该注意产品表面前处理问题,同时还应注意防止表面处理加工,加工过程和加工过程的标准严格避免白点的形成。碱洗干净的白点酸洗很好，但要控制浓度，否则喷漆，堵塞铝与氧气的接触。
　　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.
