Principle of airless spraying machine
Air assisted airless spraying, in the paint atomization point mixed with compressed air, further refining paint in the compressed air (0.2-0.5 mpa) to make paint atomization, spray to the surface of the spray formed paint film with pump pressure (about 21 mpa), from the nozzle spray atomization, spray to the surface of the spray formed paint film. Pump pressure to paint (21 mpa or so), from the nozzle spray atomization, spray to the surface of the coating.
Efficiency 400-600 square meters/hour; 3200-4800 square meters/day hand brush: 60-80 square meters/person * day roller brush: 150-200 square meters/person × day 200 square meters/person × day 3200-4800 square meters/day; 400-600 square meters/hour.
The high-pressure airless spray machine pressurizes the paint to 3000PSI (210kg/cm) with a high-pressure plunger pump to obtain the high-pressure paint and convey it to the spray gun through a high-pressure hose. The pressure is released through the nozzle to form atomization, thus forming a dense coating on the wall surface. Because paint atomization does not need compressed air, it is called airless spray.
