在卷取前，應做一些預處理工作，以保證卷取表面的清潔。避免殘余油脂和潤滑劑的存在對涂層表面和使用產生影響。因此，鋁卷成型前要對其進行以下幾個方面的預處理。
　　Before coiling, some pretreatment should be done to ensure that the coiling surface is clean. Avoid the influence of residual grease and lubricant on the surface and use of the coating. Therefore, the pretreatment of aluminium coil before forming should be carried out in the following aspects.

　　，可以用熱水清洗軋輥。熱水清洗主要是清洗基體表面殘留的脫脂劑，以確保這些殘留物能夠溶解在其中，防止這些脫脂劑對基體的二次污染。使用方式以浸洗和噴洗為主。使用的水硬度不宜過高，否則水中的礦物質會在基體表面形成礦物斑點。

　　First, hot water can be used to clean the rolls. Hot water cleaning is mainly to clean the degreaser residues on the surface of the matrix to ensure that these residues can be dissolved in it and prevent the secondary pollution of these degreasers to the matrix. The main usage methods are soaking and spraying. The hardness of water should not be too high, otherwise minerals in water will form mineral spots on the surface of matrix.
　　其次，由于預涂線速度快，用于熱堿脫脂的脫脂劑通常濃度較高。典型的脫脂劑包括氫氧化鈉(NaOH)、碳酸鈉(Na2Co3)、硅酸鈉(Na2SiO3)、磷酸鹽等成分。熱堿脫脂工藝一般分兩步進行，以保證鋁卷基材表面的清潔，常用的方法是噴刷法。
　　Secondly, due to the high speed of the pre-coating line, the degreaser used for hot alkali degreasing is usually of high concentration. Typical degreasers include sodium hydroxide (NaOH), sodium carbonate (Na2Co3), sodium silicate (Na2SiO 3), phosphate and other components. Hot alkali degreasing process is usually carried out in two steps to ensure the surface cleanliness of aluminium coil substrate. The commonly used method is spraying method.

　　后，它被鈍化。鈍化工藝是通過壓力噴涂、浸漬涂層或輥涂等方法使鈍化劑在基體表面形成轉化膜。一般采用加壓噴霧方式。鈍化液在使用過程中產生的污泥會堵塞噴嘴孔，從而影響噴霧效果。浸鍍法雖然解決了這一問題，但鈍化液消耗較大。以上兩種方法在實際操作中都需要用水清洗過量的鈍化液，這將產生廢水回收凈化的問題。輥涂是佳的鈍化施工方法，具有涂膜均勻、經濟實用、不需浸出等優點。鉻酸鹽/氧化底漆是鋁板常用的底漆，它含有鉻酸鹽、鉻酸鹽、磷酸、促進劑氟化物和鉬酸鹽。此類處理劑必須添加磷酸，否則不能用于食品飲料鋁板的處理。
　　Finally, it is passivated. Passivation process is to make the passivator form a conversion film on the surface of the substrate by pressure spraying, impregnation coating or roll coating. Generally, pressurized spray method is adopted. The sludge generated during the use of the passivation fluid will jam the nozzle orifice, thus affecting the spray effect. Although the dipping method solves this problem, the consumption of passivation solution is large. The above two methods need to use water to clean excessive passivation liquid in practical operation, which will cause the problem of waste water recovery and purification. Roller coating is the best passivation method, which has the advantages of uniform coating, economical and practical, and no leaching. Chromate/oxidized primer is a common primer for aluminium plate. It contains chromate, chromate, phosphoric acid, accelerator fluoride and molybdate. Phosphoric acid must be added to this kind of treatment agent, otherwise it can not be used in the treatment of food and beverage aluminium sheet.
　　在過去的一年里，我國鋁卷產品市場正在逐步完善，彩色鋁卷一直在穩步增長。鋁盤管在電子、包裝、施工、機械等方面的應用。在過去的2012年里,傳統的電子設備許多shell或塑料,可能便宜許多,但是生命是短暫的,外殼很容易壞,所以中鋁體積的未來發展也能夠占領市場,鋁盤管制造商將逐漸增加,產品的競爭終歸結為技術競爭和競爭。
　　In the past year, China's aluminium coil product market is gradually improving, color aluminium coil has been growing steadily. The application of aluminium coil in electronics, packaging, construction, machinery, etc. In the past 2012, many shells or plastics of traditional electronic equipment may be much cheaper, but life is short and the shell is easy to be damaged. Therefore, the future development of SinoAluminum Volume can also occupy the market. Aluminum coil manufacturers will gradually increase, and the competition of products will ultimately be attributed to technology competition and brand competition.
　　從整個市場來看，人們對產品的需求仍在增加，這對假冒偽劣產品的抵抗力很強，鋁卷也將成為我們產品的一部分，它使我們的產品更美觀，更。
　　From the whole market, people's demand for high-end products is still increasing, which is very resistant to counterfeit and inferior products. Aluminum coil will also become part of our products, which makes our products more beautiful and high-end.
