How to prevent oxidation corrosion of 1060 heat-insulating aluminum coil
Regarding the thermal insulation aluminum coil, most of the current insulation coils of the 1 series alloy are mainly used. For example, the 1060 aluminum coil is the most commonly used series of thermal insulation aluminum coils. Nowadays, with the complicated application, the application of 3003 thermal insulation aluminum coil is gradually expanding. Therefore, the current 1060 aluminum coil, 3003 aluminum coil is the most commonly used thermal insulation aluminum coil alloy. However, many customers found that there is a problem of corrosion-oxidized aluminum coils bought back after corrosion. Now I will share you how to prevent oxidation and corrosion of aluminum coils. The following is the content information.
Insulating aluminum coils are a very common type of aluminum coil in life. We all know that insulated aluminum coils are prone to corrosion. So, what is the cause of the oxidative corrosion of the aluminum coil?
Corrosion of aluminum coils: Corrosion oxidation refers to the aluminum coil before use. Due to the package state in the package, the aluminum coil is not completely exposed to the air and no protective layer is formed. In this case, the aluminum coil is not exposed to rain or moisture, and the moisture in the moisture will chemically react with the surface of the aluminum coil to form corrosion of the aluminum coil. Corrosive aluminum coils will show signs of corrosion, and the fierce state will turn black. Just like being burned by fire. However, after such corrosion occurs, the secondary damage of the aluminum coil will no longer be displayed, and the aluminum coil itself has no problem, but the appearance is impaired.
How to avoid oxidative corrosion of aluminum coils?
1. Workshop, there is a leak at the top of the warehouse.Aluminum coils should not be placed in the snow.
2. Strengthen the management of air drilling to ensure that there is no water in the compressed air.
3. Aluminum coils should be sealed and each volume should be filled with an appropriate amount of desiccant.
4. When transporting from a low temperature area to a high temperature area with high humidity, do not open the sealed package immediately.
5. Strengthen the management of rolling oil, the water content is controlled below 0.04%.
6. The wooden shaft of the box? The humidity of the box board does not exceed 18%, and the temperature of the packaged color aluminum coil does not exceed 45 °C.
Oxidation under normal conditions means that after the aluminum coil is applied to, for example, a pipe, the aluminum coil is completely contacted by air and forms an oxide film. This oxide film protects the aluminum coil from further corrosion, so it will not corrode when exposed to sunlight even if it rains again after use.
