Coated aluminum coil refers to the product that stops the color coating effect on the surface of the aluminum coil, also known as color coated aluminum coil and color aluminum coil. The purpose of stopping the coating process is to produce beautiful effects in the fields of construction, decoration, and home furnishing. At the same time, due to the difference in coating process and coating thickness, it directly affects the production, quality and service life of coated aluminum coils, and the coating process It is a key link in the consumption of colored aluminum coils and directly affects the final coating quality and product durability. Therefore, the coating process is very strict. So what is the specific process of coated aluminum coil?
The production process of ordinary coated aluminum coil is divided into five steps, namely coil input, cleaning and chemical treatment, coating, curing and waste output. The process layout and equipment composition are different under different conditions, but the basic components are the same.
1. The input of the raw material roll is the continuous uncoiling of the uncoiler to
ensure the continuous and stable input of the coil to the consumption line. Some use cross-rotating beam coilers, and some use two alternate decoilers, in short, to supply coilers in time;
2. Surface cleaning and chemical treatment are to clean the upper and lower surfaces of the aluminum coil and stop chemical pretreatment to ensure that the paint can adhere firmly;
3. painting. There are at least two roller coaters in the customer line to ensure two top coats and primers;
4. The curing of the paint layer, that is, the tape roll that has just stopped painting should be fixed before it contacts the next roller surface to prevent sticking. Generally speaking, at least two curing boxes are included;
5. It is the output of waste products to ensure that the speed of the consumption line is synchronized with the transfer of waste products.
