The high-pressure airless paint sprayer uses a high-pressure piston pump to pressurize the paint to 3000 psi (210 kg/cm), and the high-pressure paint is delivered to the spray gun through a high-pressure hose, and the pressure is released through the nozzle to form a atomization, thereby forming a dense surface on the wall. Coating. Since the atomization of the coating does not require compressed air, it is called airless spraying.
It has the following advantages:
First, extremely high coating efficiency. The spraying efficiency is up to 500-1200 square meters per hour, which is more than 10 times that of traditional drum construction.
Second, excellent surface quality. The spray coating is smooth, smooth, dense, free of brush marks, marks, and particles.
Third, extend the service life of the coating. High-pressure airless paint sprayer 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, voids and uneven brushing parts.
Fifth, save paint. The thickness of the brush is extremely uneven, generally 30-250 microns, and the coating utilization rate is low, while the airless spray can easily obtain a coating with a thickness of 30 microns, which is relatively 20-30% of the coating material.
