Generally speaking, the density of aluminum skin is relatively small, so the quality is lighter. Therefore, the aluminum skin is very easy to process and operate. This is also the reason why aluminum skin has been in the lead in the heat preservation industry for many years, and it is unkind to replace the iron skin in the pipeline. So the aluminum skin is so hot now.
The corrosion resistance of aluminum sheet is mainly shown in the following aspects:
1, the density of pure aluminum skin is relatively light, the higher the purity of aluminum skin and air contact oxidation reaction will be greater, the surface will form a very thin, very compact oxide film. And usually it is faster than other metal chemical reactions, and the thickness of the film is a little thicker. This film can better avoid contact between the microorganism and the moisture in the air.
2, the mechanical strength of aluminum skin, we will find that the stronger the corrosion resistance of the aluminum skin, the lower the mechanical strength, then in order to better solve this problem, you can add a trace of rare elements in the aluminum skin, such as manganese, magnesium and other elements. This not only increases the hardness of the aluminum skin, but also increases the mechanical strength of the aluminum skin, greatly increasing its corrosion resistance.
3, the powder coating of aluminum skin, that is, we often say color coating aluminum skin, can have various colors for everyone to choose, add the beautiful performance of aluminum skin, but according to the small editor, the pipe insulation color coating aluminum skin is still relatively small, because the cost price will increase, unless the customer has the specified requirements.
