It can be said that Changzhou aluminium art gate because of high quality, appears high-end atmosphere, so many enterprises and individuals choose. However, some people will say why the Changzhou aluminum art gate needs to enter the spray coating. Today, Xiaobian is going to give you a brief explanation. Generally speaking, aluminum is a light metal with a silver-white luster, which can be oxidized with oxygen in the air, making the surface form an oxide film, it is not so bright. And in order to avoid oxidation of aluminum and oxygen in the air, powder spraying will be carried out.
It can be said that the higher the purity of aluminum gate, the better the corrosion resistance. It is precisely because aluminum can oxidize with oxygen in the air that a protective film is formed on the surface, which can prevent the aluminum gate from being corroded. Aluminum is more resistant to corrosion than other materials because other materials are prone to change with oxygen in the air.
In addition, although the corrosion resistance of pure aluminum is very good, but the mechanical strength is very poor, it can be said that this has become a constraint in more aspects of aluminum applications. In order to improve the mechanical strength of aluminum, magnesium, copper and other metal materials will be added to aluminum to further enhance the mechanical strength of aluminum. But in this way, the corrosion resistance of aluminum will become worse, for this reason, people will also spray aluminum gate to prevent corrosion.
