Now many people will use aluminum coil, but many people are not very clear about the characteristics of aluminum coil, some people will ask whether aluminum coil can get caught in the rain, the technical staff of KK Aluminum will explain this problem to us, and tell us how to avoid the oxidation corrosion of aluminum coil, I hope it will be helpful to you.
Are aluminum rolls safe from the rain?
Be afraid! In particular, aluminum coil is strictly prohibited to be soaked or eroded by rain!
Summer, also known as the rainy season, is the season when aluminum products such as aluminum plate, aluminum coil and aluminum strip appear water corrosion and oxidation. Although there is a classification of alumina plate in aluminum plate products, but alumina plate and aluminum plate oxidation are completely different things. The difference between oxidized aluminum plate and aluminum plate:
Aluminum oxide plate generally refers to: aluminum plate after acid and alkali oxidation, the formation of a protective film on the surface of the aluminum plate. The general oxide film is silver white. If customers have special requirements, can also be oxidized to different colors according to customer requirements.
Can aluminum roll get wet
Oxidation is divided into: ordinary oxidation, anodic oxidation and hard oxidation.
Ordinary oxidation of aluminum plate refers to the formation of a protective film on the surface of the aluminum plate after cleaning the surface of the aluminum plate through acid and alkali flow groove, which is known as the oxide film.
Anodization of aluminum plate refers to a process in which the aluminum plate is energized after ordinary oxidation.
So the difference between anodic oxidation of aluminum plate and hard oxidation of aluminum plate is: the depth of anodic oxidation film is shallow, and the depth of hard oxidation film is deep.
The oxidation of aluminum plate generally refers to the same corrosion phenomenon in the aluminum plate or the part connected with aluminum coil. The size and pattern of the corrosion area are the same.
Reasons for this situation:
1. The temperature is too high when the aluminum plate or aluminum coil is packed. Steam is formed in the package, and the aluminum plate and aluminum coil are corroded by moisture.
2, aluminum plate or aluminum roll rain, so that the rain poured into the packaging. Aluminum plate, aluminum coil corrosion phenomenon.
3, in the environment of high humidity aluminum plate, aluminum coil will appear corrosion phenomenon.
How to avoid this kind of phenomenon:
1. Let the aluminum plate and aluminum roll cool naturally before packaging.
2. The fan can be used to cool the aluminum plate and aluminum coil.
3. When packing, the aluminum plate and aluminum roll are packed with plastic sheet and cardboard.
4. During the transportation of goods, the driver should be instructed to cover the tarpaulin.
5, in a large degree of environment, in the packaging to place more desiccant. And put the aluminum plate, aluminum roll in a relatively dry environment.
