Weathering treatment process of 09CuPCrNi-A

Due to the factors of different regions, environments and climate, the time for forming a stable oxide film on the surface of 09CuPCrNi-A also varies greatly. In order to form this stable oxide film early, when island countries use 09CuPCrNi-A, weather-coated treatment is required, so that 09CuPCrNi-A can more easily exert its weather-resistant and anti-corrosion properties.

The process of weathering treatment is to clean the surface of 09CuPCrNi-A steel first, and then spray a layer of weather coat solution, so some chemical elements on the surface of 09CuPCrNi-A produce electrochemical reactions to form a layer of copper, phosphorus, chromium, Nickel-iron oxide film. Then spray a layer of prepalene, prepalene is a colored mixture, including low molecular weight acrylic resin and organic solvents, because prepalene has a high ability to absorb moisture and infrared rays, it can accelerate the stabilization of the oxide film Formation. After a period of time, when the prepalene layer peels off, the solid oxide film that has been formed is enough to protect 09CuPCrNi-A from further corrosion.
