1. All surfaces of iron and steel parts that need to be painted must be removed from rust, oxide scale, grease, dust, soil, salt and dirt before painting.
2. Before removing rust, remove the grease and dirt on the surface of steel parts with organic solvents, lye, emulsifier and steam.
(3) the time interval between the coated surface and the primer can not be more than 6h after shot peening or manual rust removal.
4. Contact surfaces of riveted parts must be coated with a thickness of 30 ~ 40&mu and M antirust paint before connecting. Overlapping edges are sealed with paint, putty or adhesive. It is necessary to re coat the primers due to processing or welding damage.
