Compared with manual roll coating, it has the following advantages: First, extremely high coating efficiency. Spraying efficiency of up to 500-1200 square meters per hour, more than 10 times that of traditional drum construction

Second, excellent surface quality. The spray coating is smooth, brilliance, dense, brushless, scalding, and granules.

Third, extend the service life of the coating. High-pressure airless spraying enables the coating particles to penetrate into the wall space, so that the paint film also forms a mechanical bond on the wall surface, enhancing the adhesion of the paint and prolonging the service life.

Fourth, it is easy to overcome corners, gaps and uneven brushing parts

Fifth, save paint. The thickness of the brush is extremely uneven, generally between 30 and 250 microns.

Airless spray is easy to obtain a coating with a thickness of 30 microns, which is 20-30% relative to the coating. The airless spraying machine uses a special electric, pneumatic or other power to drive the high pressure pump to form a high pressure of 150-350 Kg/cm2 for the paint coating, and instantaneously ejects through an airless nozzle of a special shape and structure to form a very fine fan-shaped mist. The spray speed of the coating was 0.9 m/sec. All the paint is quickly sprayed onto the surface of the coating without bounce and splashing, which not only saves 40% of the paint, but also has almost no paint mist. It can be sprayed without a mask, thus reducing pollution and protecting the environment. The role. Since the effect of high pressure is 10 to 50 times higher than that of the conventional spraying machine, and the spraying speed is as high as 200 to 600 square meters per hour, not only the coating quality can be ensured, but also the coating cycle can be greatly shortened and ensured. The coating quality is bright and flat. At the same time, it can spray high-viscosity coatings, and can save thinner materials or do not add thinner materials during spraying. It can reach a thin coating of 0.05-0.25mm or even a thick coating of 1-2mm by airless spraying. Because there is no rebound force in the airless spray, it is easy to enter the corners and edges when spraying the corners and edges, so that it has a uniform bright and flat coating. Since the coating atomization mechanism is formed into a mist by the high pressure of the coating itself, and the atomized state coating does not contain compressed air, it is called airless spraying.
