Steel structure warehouse is a common architectural form in modern industry. It has the advantages of firm structure, wind resistance and earthquake resistance, and convenient construction, so it is widely used in many industries. However, steel structure warehouses also face the problem of corrosion during long-term use. If anti-corrosion treatment is not carried out in time, its service life and safety will be affected. Therefore, this article will introduce how to carry out anti-corrosion treatment for steel structure warehouses.
First, understand the corrosion of steel structure warehouses
Before carrying out anti-corrosion treatment, it is necessary to understand the corrosion situation of the steel structure warehouse in order to choose a suitable anti-corrosion method. The corrosion of steel structure warehouse mainly comes from the following aspects:
1. Atmospheric corrosion: The steel structure warehouse is exposed to the atmospheric environment for a long time, and is corroded by air, water vapor, acid rain, etc., causing the surface to rust.
2. Soil corrosion: There are various types of soil under the foundation of the steel structure warehouse, and the acid and alkali substances contained in it will corrode the steel structure.
3. Chemical corrosion: Steel structure warehouses may be corroded by various chemical substances during use, such as acid and alkali solutions, chloride ions, etc.
Second, choose the appropriate anti-corrosion method
According to the corrosion situation of the steel structure warehouse, it is the key to choose the appropriate anti-corrosion method. Commonly used anti-corrosion methods include:
Spraying anti-corrosion paint: This is one of the most common anti-corrosion methods, which can form a layer of anti-corrosion layer on the surface of the steel structure to prevent atmospheric corrosion and chemical corrosion. However, this method is not very good at preventing soil corrosion.
Hot-dip galvanizing: This method can form a zinc layer on the surface of the steel structure to prevent atmospheric corrosion and soil corrosion. However, it is not effective for chemical corrosion, and the cost is high.
Seal coating: This method can form a waterproof layer on the surface of the steel structure to prevent soil corrosion and chemical corrosion. However, it is not effective for atmospheric corrosion.
Anodic protection: This method utilizes the steel structure as an anode to form a protective layer on its surface to prevent chemical corrosion. However, it is not effective for atmospheric corrosion and soil corrosion.
According to the environment and conditions of the steel structure warehouse, it is very important to choose the appropriate anti-corrosion method. At the same time, attention should be paid to the selection of anti-corrosion materials and construction quality to ensure the anti-corrosion effect.
Third, strengthen maintenance
After the steel structure warehouse has undergone anti-corrosion treatment, it still needs to strengthen maintenance to prolong its service life. Specific measures include:
1. Regular inspection: Regularly check whether there is corrosion on the surface of the steel structure and deal with it in time.
2. Cleaning and maintenance: Regularly clean the corrosion on the surface of the steel structure and keep the surface clean and dry.
3. Repair paint coating: If the paint layer on the surface of the steel structure is found to be damaged or peeled off, it needs to be repaired in time.
4. Do a good job of waterproofing: the waterproofing of steel structure warehouse is also very important, and methods such as waterproof coatings or waterproof membranes can be used.
5. Prevent collision and wear: The surface of the steel structure warehouses are prone to collision and wear, so care should be taken to avoid these situations.
By strengthening maintenance, the service life of the steel structure warehouse can be extended, and its safety and stability can be improved.
In short, the anti-corrosion treatment of steel structure warehouses is very important, which can ensure the safety and stability of its long-term use. When carrying out anti-corrosion treatment, the appropriate anti-corrosion method should be selected according to the specific situation, and maintenance work should be strengthened to ensure its effectiveness and durability.
