    Color Coating Aluminum Sheet Production Line

    The printing production line of colored aluminum plate is a complete of production equipment for colored aluminum plate, and the process is as follows: make the aluminum coil strips be subject to surface degreasing treatment, then apply multi-layer organic coatings (e.g., nano-coating, self-cleaning coating, scratch-resistant coating, fingerprint-resistant coating etc.) on the strip surface by means of continuous roller coating, next, overprint multi-color patterns, and finally bake and cure to form composite material. The production line is composed of equipment of uncoiler, sewing machine, storage machine, degreasing and washing unit, roller-coating machine, printing machine, curing furnace, shear, coiler etc.. 

    I. Process Parameters

    1. Base plate: hot aluminum plate, aluminum alloy plate

    2. Thickness of strip: 0.09-3.0mm

    3. Width of strip: 800-1800mm

    4. Outer diameter of aluminum coil: φ800-2000mm

    5. Process speed: 30-180m/min

    III. Equipment Characteristics

    1.The application of roller coating method having advanced process and high chemical film quality guarantees the performance and quality of the coating of colored plates. Besides, the chemical treatment agent is almost used one hundred percent without pollution and waste, and the chemical film is even and dense.

    2.The roller-coating machine is equipped with pressure sensor to precisely display the pressure of coating roller, which can precisely control the coating evenness, and through the variable-frequency speed control of vector motor, the machine can execute forward or backward coating operation and can precisely control the thickness of coating to be within 1 micrometer, so as to adapt to the production requirements of various products.

    3.The coating curing and drying furnace adopts multi-layer labyrinth flashboard structure having good thermal insulation effect, and has multiple sets of hot air circulating devices and have functions of air distribution and management, waste gas collection and decomposition treatment, automatic temperature control etc.; it is equipped with VOC incineration device as well as perfect and fine waste heat recycling device, and the exhaust gas meets the national environmental emission standard, which really achieves energy-saving and consumption reduction effect. The technical level of organic waste gas decomposition and heat utilization is second to none in China.

    4.The printing process adopts three-color over-printing technology and the printer adopts digital control technology, making the thickness of printing coat be less than 1 micrometer and match color automatically, thus to effectively control the printing precision and color.

    5.The control system adopts computer control systems of variable-frequency speed control of vector motor, site bus and fiber communication and real-time parameter monitor technology, with good human-machine interface and safe, stable and reliable equipment operation.

    6.Introduce the concepts of intelligent production and energy management system, and configure multiple technical devices for fine regulation of energy saving, consumption reduction and production control, e.g., variable-frequency fan etc..
