AI Technical Summary
During the application of existing anti-rust spraying equipment to the outer wall of steel chimneys, electrostatic adsorption and residual magnetic forces cause the adsorption of heterogeneous particles such as metal debris and dust, forming micro-protrusion structures. This disrupts the continuity of the paint film, reduces the interfacial bonding strength, and diminishes the durability of the anti-corrosion coating.
A rust-preventive spraying device was designed, comprising a support plate, a guide positioning ring, a guide slide plate, a magnetic block, a cleaning wheel, and a purification collection box. Through magnetic adsorption fixation, the cleaning wheel removes impurities, and the purification collection box collects mist, ensuring the cleanliness of the steel chimney surface and achieving uniform spraying and continuous rust-preventive paint application.
It improves the uniform adhesion and film continuity of the anti-rust paint, enhances the physical barrier function and long-term durability of the anti-corrosion coating, and improves the quality of the spraying environment and operational safety.
