涂层铝卷生产工艺有哪些步骤

涂层铝卷是指在铝卷材表面具有彩色喷涂效果的产品，又称彩色镀铝卷材和彩色镀铝卷材。涂层处理的目的是在建筑、装饰、家居等领域具有美观的效果；二是涂层铝卷涂层工艺和涂层厚度直接关系到涂层铝卷的产品质量和使用寿命。

镀膜工艺是彩色铝卷生产的关键步骤， 涂层铝卷直接影响到最终的镀膜质量和产品的耐久性。因此，涂装工艺非常严格。随着涂装设备的不断改进和新型涂料的开发利用，镀铝卷材的生产日趋成熟，加工成本也在不断降低。因此，镀铝卷材得到了迅速的发展。那么镀铝卷材的具体工艺是什么呢？
涂层铝卷卷材涂料的生产过程一般有五个步骤：卷材投入、清洗和化学处理、涂装、固化和成品输出。不同情况下的工艺布置和设备组成不同，但基本部件相同。
1、 原料卷的投入是开卷机的连续开卷，以保证卷料连续稳定地投入生产线。有的采用十字旋转梁式卷取机，有的采用两套交替开卷机，总之是为了及时供卷；

2、 表面清理和化学处理是指铝卷的上下表面必须清理干净，并进行化学预处理，确保油漆能牢固附着；
3、 这是绘画。一条生产线至少有两台辊涂机，保证两道面漆和底漆；
4、 指漆层的固化，即刚涂完漆的带卷在接触下一辊面前应先固定好，以免相互粘连和损坏。一般来说，它至少包含两个固化盒；
5、 是成品输出，保证生产线速度与成品辊转移同步。

Coated aluminum coil refers to a product with color spraying effect on the surface of aluminum coil, also known as color coated aluminum coil and color coated aluminum coil. The purpose of coating treatment is to have beautiful effect in construction, decoration, home and other fields; the second is because the coating process and coating thickness are directly related to the product quality and service life of coated aluminum coil.

Coating process is a key step in the production of color aluminum coil, 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 coil is more mature, and the processing cost is also decreasing. Therefore, coated aluminum coil has obtained rapid development. So what is the specific process of coated aluminum coil?
Generally, the production process of coil coating has five steps: coil input, cleaning and chemical treatment, painting, curing and finished product output. The process layout and equipment composition are different in different situations, but the basic parts are the same.
1、 The rawmaterial coil input is the continuous uncoiling of Uncoiler to ensure the continuous and stable input of the coil into the production line. Some adopt the cross rotating beam coiler, and some adopt two sets of alternate uncoilers, in short, it is for timely coil supply;

2、 Surface cleaning and chemical treatment means that the upper and lower surfaces of aluminum coil must be cleaned, and chemical pretreatment shall be carried out to ensure that the paint can adhere firmly;
3、 It is painting. There are at least two roller coating machines in one production line to ensure two layers of finish and primer;
4、 It refers to the curing of the paint layer, which means that the tape coil that has just been painted should be fixed before contacting the next roll surface, so as to avoid adhesion and damage to each other. Generally speaking, it contains at least two curing boxes;
5、 Is the finished product output, to ensure that the production line speed and finished roll transfer synchronization.
