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.

涂层工艺是彩色铝卷生产中较为关键的步骤，直接影响较终的涂层质量和产品的耐用性。因此，涂层工艺十分严格。随着涂层设备的不断完善，新型涂料的开发利用，使得涂层铝卷的生产更加成熟，加工费也在下降。涂层铝卷因此获得了迅速的发展。那么涂层铝卷的具体工艺是怎样的呢?

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?

Aluminum coil

一般带卷涂层的生产工艺有5个步骤，即带卷输入、清洗与化学处理、涂漆、固化和成品输出。不同情况的工艺布置和设备组成有所差别，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、原料卷输入，是开卷机连续开卷保证带卷连续稳定输入生产线，有的采取十字转动梁式载卷机，也有采取双台前后设置交替开卷机，总之是为了及时供卷;

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、表面清洗和化学处理，是使铝卷上下表面必须清洗干净，进行化学预处理，为了保证油漆能够牢固附着;

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、是涂漆，一条生产线至少有两个以上辊涂机，保证面漆和底漆两层涂色;

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、是漆层固化，指的是刚进行涂漆的带卷要在接触下一个辊面之前完成固话，避免互相粘连和破坏，一般来讲，至少包含两个固化箱;

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、是成品输出，保证生产线速度与成品卷转移同步。

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