How to choose painting equipment correctly

Painting from the time and labor consumption of manual work era, low efficiency, to today's painting equipment to achieve industrial production, after corrosion prevention, beauty, efficiency, environmental protection and other stages. We believe that with the continuous development of mechanical equipment research and development, the development of electronic technology, numerical control technology, laser technology, microwave technology and high voltage electrostatic technology, the automation, flexibility, intelligence and integration of coating equipment have been more professional applications, so that the varieties of machine tools continue to increase, and the technical level continues to improve. Better for wood products enterprises to achieve industrialization, large-scale production to provide help.

Roll coating is the coating method of rolling on the surface of the workpiece by dipping the paint in the roller. Generally divided into manual roll coating and machine roll coating, suitable for flat workpiece coating. Its advantages are less paint waste, not easy to form paint dust, good environmental protection, high work efficiency. One of the advantages of roller coating compared with spraying is that it does not produce paint fog during the construction process, and there is no spray of paint fog. The mechanical roller coating can operate automatically at high speed, the coating speed is fast, and the production efficiency is high. Both low and high viscosity coatings can be adapted in roll coating operations to complete both front and back coating. After the development of mechanical roller coating, the combination of UV dryer can achieve the effect of instant drying, and the direct spraying of the top paint at the end of the primer, greatly saving the time cost and improving the work efficiency. In modern roller coating, in order to pursue higher environmental protection, UV green environmental protection paint will be used to reduce VOC by more than 80%.

Spraying A coating method in which droplets are dispersed into uniform and fine droplets and applied to the surface of the coated material by means of pressure or centrifugal force, either by a spray gun or a dish atomizer. It can be divided into air spraying, airless spraying, electrostatic spraying and various derivative methods of the above basic spraying forms. Spraying operation has high production efficiency and is a common coating method in today's applications. Usually, the main problem in spraying is the highly dispersed paint mist and the volatile solvent, which not only pollutes the environment, is not conducive to human health, but also wastes paint and causes economic losses. Nowadays, in order to meet the needs of development and environmental protection, great progress has been made in the technology and environment of spraying. For example, the entire painting process is carried out in the vacuum box, which is not harmful to the environment and the operator, and 100% recycling in the spraying can also reduce costs.

Spray coating is a coating method in which the paint is stored in a high slot, drizzled from above through a nozzle or narrow slit, and showered on the coated material driven by the transfer device in a curtain shape to form a uniform coating film, and the excess paint flows back to the container and is pumped to the high slot for recycling. Coating includes manual operation and through the coating equipment operation, the former has low production efficiency and high labor intensity. The latter is suitable for large-scale continuous production and has high production efficiency. The multi-functional UV coating in modern coating has high efficiency, low labor intensity, and can form a continuous operation of the production line. And it has the advantages of high utilization rate of paint, less volatilization of paint, double shower head, two-component coating and so on.
