Color coated aluminum coils are widely used in many places, and their production process is also relatively complex and strict, especially in terms of coating. It is generally believed that to ensure its coating effect, the following aspects must meet certain requirements.
Coatings and aluminum plates are the factors that can most affect the coating quality during the coating process. Due to color differences between batches of coatings, insufficient coating fineness and low coating rate, poor coordination between coatings and solvents, layering, etc., they can directly affect the coating effect and produce defects. The unevenness of the aluminum coil substrate, uneven film thickness, and poor edge deflection also directly affect product quality and overall use. Therefore, strict control should be exercised when selecting raw materials.
The coating line requires the coating equipment to be in good condition, the coating equipment to operate smoothly, without horizontal or vertical shaking, and the coating rollers to be finely ground. The lateral runout of all rollers in the coating machine must be controlled within the allowable range, otherwise it will seriously affect the surface quality of the coating.
The coating process has a close relationship with the quality of the coating, and it is required to control the relative linear velocity ratio of the coating roller, paint lifting roller, measuring roller, and substrate within a certain range. According to different systems and film thicknesses of coating products, a certain viscosity range should be set for the coating to ensure smooth coating and promote the improvement of product quality. Lamination is a physical process in which one layer of film and one layer of aluminum plate are pressed together under high temperature and pressure. The advantage of the lamination process is its resistance to oil fumes. Made of PVC high gloss film, easy to clean. Wear resistant, unique PET layer, sturdy and durable. Moisture-proof, surface coated, reducing direct contact between water and aluminum, with strong durability. Good touch, with a layer of film on the surface, smooth touch, changing the cold and single feeling of the metal material. There are many designs and colors to choose from.
