High pressure airless sprayer is an advanced coating method in the industry. It relies on a booster pump to pressurize the paint to a high pressure of 60-300kg/cm², and then sprays it through fine spray holes to form a fan-shaped mist.
When spraying large panels, the flow rate can reach 3-5 cubic meters per minute, and it can also accommodate high-viscosity thick paints. Since no air is mixed during the spraying process, the paint transfer efficiency and construction efficiency are both superior. It can form a dense coating on walls and metal surfaces, and the overall coating effect is far superior to traditional air spraying.
Its core advantages are reflected in these five points:
- The construction efficiency is extremely high, with a spraying area of 500-1200 square meters per hour. The efficiency is more than 10 times that of traditional roller construction and more than 3 times that of air spraying, significantly shortening the construction period.
- The decorative finish is of high quality. After spraying, the coating is smooth, dense, and uniform, with no brush marks, roller marks, or particulate impurities. The surface texture far exceeds that achieved through traditional construction methods.
- Extending the Lifespan of the Coating: The coating particles can penetrate deep into the fine pores of the wall, forming a mechanical bond with the substrate, significantly enhancing the adhesion of the paint film and effectively extending the service life of the coating.
- It can easily achieve uniform spraying in complex areas such as corners, gaps, uneven surfaces, and other traditional painting difficulties, and is suitable for various irregular substrates.
- Saving Paint Costs: Traditional brushing results in uneven coating thickness (30-250 micrometers), leading to significant paint waste; high-pressure airless spraying can consistently produce a uniform coating of 30 micrometers, saving 20%-30% of paint.
