Steel structure is an important material that is widely used in construction, bridges, and other engineering fields.
In order to prolong the service life of the steel structure and protect it from corrosion and rust, the anti-corrosion and anti-rust measures of the steel structure are particularly important.
This article will deeply analyze the methods and principles of anti-corrosion and anti-rust of steel structures, and derive some related content to make it richer.
1.The main principle of anti-corrosion and anti-rust of steel structure is to prevent the erosion of steel by oxygen, moisture, corrosive media, etc. by isolating the contact between steel and the external environment.
Common anti-corrosion and rust protection methods include physical, chemical, and electrochemical protection.
2.Physical ProtectionPhysical protection refers to the isolation of the steel structure from contact with hazardous substances through physical barriers.
Commonly used methods of physical protection include coatings and coverings.
The coating is to coat the surface of the steel structure with anti-corrosion paint and anti-rust paint to form a protective film.
The cladding can be plastic film, glass fiber and other materials, which effectively isolates the direct contact between the steel and the external environment.
3.Chemical protectionChemical protection refers to the use of special chemicals to form a protective film to prevent steel from corroding.
For example, chemical products such as anti-corrosion coatings and rust inhibitors are used to form a protective layer that isolates the steel structure from contact with the outside world.
At the same time, choosing the right coating thickness and quality is also an important factor in ensuring the effectiveness of chemical protection.
4.Electrochemical ProtectionElectrochemical protection prevents corrosion by applying an electric current to the surface of the steel to create a protective potential.
This method is mainly suitable for occasions that are prone to galvanic corrosion, such as marine environments.
Commonly used electrochemical protection methods include anodic protection and cathodic protection, which protect steel through positive and negative protection.

The influence of the environment on the corrosion of the steel structure In addition to the anti-corrosion and anti-rust method of the steel structure itself, the environmental conditions will also have an impact on the corrosion of the steel structure.
For example, in humid and rainy areas, moisture in the air can promote corrosion of steel;
In industrial areas, corrosive gases in the atmosphere can accelerate the corrosion of steel.
Therefore, under different environmental conditions, different anti-corrosion and anti-rust methods should be selected, and the monitoring and maintenance of steel structures should be strengthened.
Summary: As an important building material, steel structure plays a vital role in its service life due to anti-corrosion and rust prevention measures.
Physical, chemical, and electrochemical protection are common methods of anti-corrosion and rust protection.
At the same time, environmental conditions will also have an impact on the corrosion of steel structures, so it is necessary to choose appropriate anti-corrosion and anti-rust measures according to different environments, and strengthen the monitoring and maintenance of steel structures to ensure their long-term and stable use.
