Airless paint sprayer construction

The principle of the high-pressure airless paint sprayer for piston pump through a booster pump (general), so paint supercharged (up to 210KG/CM2, or even higher), high-pressure paint through high-pressure pipe to a special high-pressure gun from special The nozzle pressure was released and achieve the purpose of dispersing atomization at high speed coating to be coated. So called paint atomization without compressed air, airless spray. The spray technology since the invention of a wide range of applications, such as automobiles, aircraft, construction machinery, trains, ships, containers, etc.. With the continuous development of architectural coatings, airless spray technology is gradually applied to the construction industry, such as latex paint, oil paint, water-based paint, resin paint spraying. And gained popularity abroad. The advantages are as follows:
1, an excellent surface quality.High-pressure airless paint sprayer sprayed on the wall to form a smooth, dense coating, no brush marks, the brush roll incomparable.
2, a high coating efficiency. Single operation the coating efficiency up to 300-500 square meters / hour, which is 10-15 times manual brushing.
3, the delay of the life of the coating. Airless spray, it uses high- pressure spray atomization, paint tablets get strong kinetic energy depth wall porosity, the film and the wall to form a mechanical occlusion, to enhance the adhesion of the coating to prolong life.
4, brushing, roller coating thickness is very uneven, typically 30-200 microns, low utilization. Without gas spray coating thickness and uniform thickness of about 30 microns, high utilization.
5, around the corner and the gap can also be a good painting. Paint spray without air, the paint easily reach these parts.
