Atmospheric corrosion environment
Atmospheric corrosion environment
In daily life, various steel structures can be seen everywhere. The steel structures in the atmospheric environment are affected by sunlight, wind and sand, rain and snow, frost and dew, and changes in temperature and humidity throughout the year. Among them, the oxygen and moisture in the atmosphere cause outdoor steel structures. An important factor for corrosion, industrial gases that cause corrosion of steel structures contain SO2, CO2, NO2, CI2, H2S, NH2, etc. Although these components are small in content, the corrosion hazards to steel cannot be ignored, of which SO2 has the greatest impact. CI2 can destroy the passivation film on the metal surface and cause the problem of electrochemical corrosion of metal materials, which not only wastes natural resources, causes economic losses, and sometimes brings certain social harms.
Common atmospheric corrosion environment
Bridge
The bridge is suffering from corrosion in environments such as heat and humidity, acid rain, salt spray, industrial atmosphere, and marine atmosphere.
Corrosion, the design requires anti-corrosion years, decoration, gloss and color retention, easy maintenance

Venue
Steel structure is a structure mainly composed of steel materials, connected by bolts or rivets. The steel structure of stadiums is commonly used to form a long-term anti-corrosion structure with aggravating corrosion paint, or it is coated with supporting heavy anti-corrosion paint for protection
