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 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.
Brief introduction of production process of color coated aluminum coil (aluminum magnesium manganese color coating)
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 developed rapidly. So what is the specific process of coating aluminum coil?
Generally, the production process of coil coating has five steps, i.e. 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.
Brief introduction of production process of color coated aluminum coil (aluminum magnesium
manganese color coating)
1、 The input of raw material roll 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 type coiler, and some adopt two
sets of alternating uncoiler in front and back, in short, it is for the timely supply of coil
2、 Surface cleaning and chemical treatment are to make the upper and lower surfaces of the aluminum coil clean and carry out chemical pretreatment to ensure
that the paint can adhere firmly;
3、 A production line has at least two roller coaters to ensure two coats of finish and primer;
4、 It refers to the curing of the paint layer, which means that the coil just being painted shall be fixed before
contacting the next roll surface to avoid adhesion and damage to each other. Generally speaking, it includes at least two curing boxes;
5、 It is the output of finished products to ensure that the speed of the production line and the transfer of
finished products are synchronous.
