Rust finish process:
Step 1. The steel surface by shot peening or pickling to remove the surface scale.
Step 2. Preparation of weathering steel surface treatment agent, the weight percentage of 0.1% ~ 3% NaCl, 0.3% ~ 3% FeSO4 , 0.1% ~ 3% CuSO4 and 0.3% ~ 3% NaHSO3 mixed with water and poured into the barrel, Uniform until the solution was sky blue.
Step 3. Will be equipped with a good surface treatment agent into the sprayer, spray evenly on the steel surface for 3-5 seconds to the surface of the steel into a brown, spray finished once, so that the steel surface dry naturally, this time with suction absorbent material steel structure The lower part of the residual liquid, to ensure that the upper and lower drying time consistent until the steel structure after drying, repeat the spraying and drying process 2 times to ensure that the corten steel surface to generate a uniform and dense rust layer.
Due to the high corrosion resistance of corten steel sheets, it normally takes from 1 to 2 years from a completely new steel sheet to the formation of a stable, dense, rust-red protective layer (50-100mic thick) in natural environments. For some dry areas May be even longer.If you want to generate a simple uniform rusty yellow, it also takes about 1 month.In the process, the components of the color will occur uncontrollably, from blue and black to orange red, then rusty red, the last reddish brown Dramatic, uneven change process.
