Advantages of high pressure airless spraying used in wall roof painting construction

    High pressure airless spraying, normally refers to the use of high pressure plunger pump, directly pressurize the paint, form a high pressure paint, spray the muzzle to form atomized air acting on the surface of the object. Compared with gas spraying, the paint surface is uniform and has no granular feeling. Due to its isolation from the air, the paint is dry and clean. Airless spraying can be used for the construction of high-viscosity paint, and the edge is clear, and even can be used for some spraying projects with boundary requirements. Widely used in ships, vehicles, steel structural parts, Bridges, petroleum, petrochemical, construction and machinery industries.

    Advantages of airless spraying:
1. High construction painting efficiency Airless spraying efficiency is 3 times higher than air spraying, more than 10 times higher than brush painting, especially suitable for spraying large workpieces and large-area workpieces. Airless spraying can obtain thicker coating film, reduce spraying times and improve painting efficiency.
2. Good film quality Airless spray paint mist does not contain compressed air, no rebound phenomenon, reduce the spray caused by the paint mist flying, to avoid the compressed air of water, oil, dust into the film, improve the quality of the film.
3. Reduce pollution to the environment airless spray does not use air atomization, paint spray less splash, paint does not need to add diluent or only add a very small amount of diluent, greatly reducing VOCs emissions, conducive to environmental protection.
4. Wide adaptability to the viscosity of the paint because the transportation and spraying of the paint are carried out under high pressure, high viscosity paint can be sprayed. Choose an airless spray machine with relatively large pressure, and even spray liquid coatings or coatings containing fibers.
However, it should be noted that airless spraying is not suitable for small workpieces, and there are requirements for equipment and construction technology, and the operator needs protection.
