Before rust removal of steel structures, the surface of steel components must be cleaned. The rust removal method should meet the design requirements or be determined according to the type of coating used, and achieve the rust removal grade specified in the design. The commonly used rust removal methods include spray rust removal, projectile rust removal, manual and power tool rust removal, etc
1. Manual rust removal. Manual operation with wire brush is convenient for construction, but it has low production efficiency, high labor intensity, poor rust removal quality, and pollutes the environment. It can only be used for local rust removal.
2. Rust removal of power tools. It is a method that uses compressed air or electric energy as power to cause the casting removal tool to produce a four sided or reciprocating motion, and uses friction and impact generated when in contact with the steel surface to remove oxide scale and rust. This method is more efficient and of better quality than manual rust removal, and can generally be used.
