How to solve the oxidation problem of galvanized sheets

Galvanized sheet is a product that has been galvanized on the surface of the steel sheet and has good corrosion resistance and anti-rust properties. However, during use, oxidation of the galvanized layer may occur, affecting the service life of the galvanized sheet. To solve this problem, the following measures can be taken:

1. Improve the quality of galvanized layer

The quality of the galvanized layer is an important factor affecting the oxidation of galvanized sheets. Advanced galvanizing technology and equipment can be used to control the composition, temperature, acidity and other parameters in the galvanizing solution to ensure that the quality of the galvanized layer meets standard requirements, thereby improving the corrosion resistance and oxidation resistance of galvanized sheets.

2. Use appropriate alloy elements

Adding a certain proportion of alloying elements during the galvanizing process can improve the oxidation resistance of the galvanized layer. Appropriate alloy elements can be added according to customer requirements and specific usage environments to increase the service life of galvanized sheets.

3. Strengthen the surface treatment of galvanized sheets

In the production process of galvanized sheets, surface treatment is also a very important step. Use surface treatment methods such as sandblasting, painting, and plastic spraying to make the surface of the galvanized sheet smooth and flat, avoiding problems such as bulges and depressions on the surface, thereby increasing the adhesion between the galvanized layer and the oxide layer and reducing the risk of oxidation. possibility.

4. Pay attention to the storage and use environment of galvanized sheets

During storage and use, galvanized sheets should be protected from moisture, acidity, alkalinity, high temperature and other environments. The following measures can be taken to ensure the storage and use environment of galvanized sheets:

(1) Store in a dry, ventilated and dark place, away from direct sunlight and rain.

(2) During storage, contact with chemicals such as acids and alkalis should be avoided.

(3) During transportation and handling, appropriate protective measures should be taken to avoid scratches and collisions on the surface of galvanized sheets. 

(4) During use, you should avoid being affected by high temperature and humid environments to avoid surface oxidation problems.
