Coated aluminum coil refers to a product that undergoes color spraying on the surface of the aluminum coil, also known as colored coated aluminum coil or colored aluminum coil. The purpose of coating treatment is to achieve aesthetic results in fields such as architecture, decoration, and home decoration; The second reason is that the coating process and thickness directly affect the product quality and service life of coated aluminum coils.

涂層工藝是彩色鋁卷生產中較為關鍵的步驟，直接影響較終的涂層質量和產品的耐用性。因此，涂層工藝十分嚴格。隨著涂層設備的不斷完善，新型涂料的開發利用，使得涂層鋁卷的生產更加成熟，加工費也在下降。涂層鋁卷因此獲得了迅速的發展。那么涂層鋁卷的具體工藝是怎樣的呢?

The coating process is a crucial step in the production of colored aluminum coils, which directly affects the final coating quality and product durability. Therefore, the coating process is very strict. With the continuous improvement of coating equipment and the development and utilization of new coatings, the production of coated aluminum coils has become more mature, and processing costs are also decreasing. As a result, coated aluminum coils have achieved rapid development. So what is the specific process for coating aluminum coils?

一般帶卷涂層的生產工藝有5個步驟，即帶卷輸入、清洗與化學處理、涂漆、固化和成品輸出。不同情況的工藝布置和設備組成有所差別，但基本部分是相同的。

The production process of coil coating generally consists of five steps, namely coil input, cleaning and chemical treatment, painting, curing, and finished product output. The process layout and equipment composition vary in different situations, but the basic parts are the same.

一、原料卷輸入，是開卷機連續開卷保證帶卷連續穩定輸入生產線，有的采取十字轉動梁式載卷機，也有采取雙臺前后設置交替開卷機，總之是為了及時供卷;

1、 The input of raw material coils is achieved through continuous uncoiling by the uncoiler to ensure continuous and stable input of the coil into the production line. Some adopt a cross rotating beam type coil loading machine, while others adopt two sets of alternating uncoilers in front and back settings, in order to provide timely coil supply;

二、表面清洗和化學處理，是使鋁卷上下表面必須清洗干凈，進行化學預處理，為了保證油漆能夠牢固附著;

2、 Surface cleaning and chemical treatment ensure that the upper and lower surfaces of the aluminum coil must be cleaned thoroughly and undergo chemical pre-treatment to ensure that the paint can adhere firmly;

三、是涂漆，一條生產線至少有兩個以上輥涂機，保證面漆和底漆兩層涂色;

3、 It is painting, and a production line should have at least two or more roller coating machines to ensure that the top coat and primer are coated with two layers of color;

四、是漆層固化，指的是剛進行涂漆的帶卷要在接觸下一個輥面之前完成固話，避免互相粘連和破壞，一般來講，至少包含兩個固化箱;

4、 It refers to the curing of the paint layer, which means that the newly painted coil needs to be fixed before touching the next roller surface to avoid mutual adhesion and damage. Generally speaking, it includes at least two curing boxes;

五、是成品輸出，保證生產線速度與成品卷轉移同步。

5、 It is the output of finished products, ensuring that the production line speed is synchronized with the transfer of finished rolls.
