Although galvanized sheets can reduce the occurrence of corrosion to a certain extent, if they are exposed to an inappropriate environment for a long time, oxidation may occur on the surface of the galvanized sheets, resulting in white rust, and even other phenomena. corrosion phenomenon. So what are the factors that affect the corrosion of galvanized sheets? The following is a brief introduction to galvanized sheet manufacturers.
1. Air humidity
GNEE galvanized sheet manufacturer introduces that galvanized sheet is a layer of zinc element cast on the surface of ordinary steel sheet to protect the steel sheet inside. Because the new element itself is not easy to corrode, but the galvanized sheet will be used throughout the entire use cycle. Inside, the hot-dip galvanized layer on the surface may be oxidized by air to form white rust. Since the air contains water vapor, when the temperature is constant, if the air humidity is relatively low, the rust rate will be slower. If the air humidity slowly increases beyond a certain level, the galvanized sheet will rust. The speed will suddenly increase significantly.
2. Ambient temperature
GNEE galvanized sheet manufacturer found that under certain ambient temperature and humidity conditions, when metal materials are corroded, the temperature rises faster and the rust rate will also accelerate. If the ambient temperature drops significantly, a "essence" phenomenon will appear on the metal surface, which will accelerate corrosion. Therefore, the GNEE galvanized sheet manufacturer believes that if the temperature difference between day and night is large, or the temperature difference between indoor and outdoor is large, essence may be produced, thereby accelerating corrosion. Therefore, the highly praised GNEE galvanized sheet manufacturer emphasizes that when it is wet, In areas with high air humidity or hot and rainy areas, it is easy for the metal materials on the surface of galvanized sheets to rust.
In short, GNEE galvanized sheet manufacturers believe that the main factors that affect the corrosion of galvanized sheets include air humidity and environment. In addition, GNEE galvanized sheet manufacturers found that if carbon oxide penetrates into the metal material, it will accelerate corrosion. In addition, various GNEE galvanized sheet manufacturers emphasize that environmental pollution factors will also have a certain impact on the running of galvanized sheets. Therefore, they want to better protect galvanized sheets and prevent galvanized sheets from corrosion and rust. , you need to pay attention to the above factors.
