Problems solved by technology

[0002] Steel is widely used in mechanical equipment, building decoration and other fields. The problems of corrosion of steel surface and electrostatic charge electromagnetic interference have always been problems that people need to solve urgently. Especially steel is widely used in outdoor environment because of its good mechanical strength. The outdoor ambient temperature , humidity and ultraviolet rays will cause corrosion on the surface of steel, and because steel is a conductor, static electricity has become a safety hazard during use
[0004] At present, the steel surface before painting is mainly treated by sandblasting. Although this treatment process can obtain a certain degree of cleanliness and different roughness on the steel surface, and improve the mechanical properties of the steel surface, the working environment of the operator is A large amount of dust pollutes the environment, seriously endangering the health of operators, and it is easy to cause uneven distribution of sand particles on the steel surface during the sandblasting process, which will adversely affect the bonding force between the coating and the steel surface
