project oveeel strueture anticorrosion, surface treatment at the grass-roots level directly influences the quality of the anticorrosive coating adhesion, so must use electrie grinding machine, wire brush on the surface of the steel strueture for grinding processing. The surface of the rust removal is cleaned before the coating and the surface of the steel strueture is not oxidized, dust, etc. , and then the coating is applied to prevent the secondary rust.
Surface pretreatment: steel before entering the derusting, confirm there is no grease and other pollutants such as surface, if any, using alkaline cleaner or fresh water to remove grease and dirt on the surface of the strueture, soluble salts and other pollutants. After cleaning, after natural air drying, can be followed up.
The welding and appearance of the inspection strueture after cleaning the st eel surface to find the defec ts of the st rue ture and deal with them in time.
Use electrie wire brush, polishing machine and other power tools to remove the surface of the steel. Some free edge, angular use mill processing to R is greater than 2mm. Remove all welding slag, splash and weld beans. The edge and stoma are patched and smoothed. Manual welds are honed to reduce the sharp surface. For repairing the surface o
