The ASTM corten B weathering steel plates usually need weather resistance treatment when applied in the island state, so as to better play the characteristics of weatherproof and anti-corrosion.
The weathering treatment process of ASTM corten B weathering steel plates is to clean the surface of Corten B steel first, and then spray a layer of weatherproof solution, and thus some chemical elements on the corten B weathering steel plates surface produce electrochemical reflection, forming a layer of copper, phosphorus, chromium, nickel iron oxide film. Then spray a layer of prepalene, which is a mixture of colors, including low molecular weight acrylic resin (acrylicresin) and organic solution. Because prepalene is highly absorbent and it absorbs infrared rays, it can accelerate the formation of stable oxide films on ASTM corten B weathering steel plates. After a period of time, that is enough to protect corten B weathering steel plates from continuing to corrode.
After weather resistance treatment, the ASTM corten B weathering steel plates will form a stable oxide film on the surface, so there is no rust stripping and pollution problems can be avoided. Meanwhile, the surface of ASTM corten B weathering steel plates become very smooth.
