The grades and varieties of aluminum alloy building profiles in China are comparable with those in foreign countries.

The products can be divided into: anodized profile, electrophoretic coating profile, powder coating profile, fluorocarbon coating profile, insulation profile.

Aluminium profiles are aluminium materials with different cross section shapes obtained by hot melting and extrusion of aluminium rods.

The production technology of aluminum profile mainly includes casting, extrusion and coloring.

Among them, coloring mainly includes oxidation, electrophoresis painting, fluorocarbon spraying, powder spraying, wood grain transfer printing and other procedures.

Next, Zhanyao paint will introduce the application of aluminum profile spraying equipment in the production process.

1. The higher the purity, the better the corrosion resistance.

It is well known that pure aluminum reacts with oxygen in the air to form a very thin and dense natural oxide film on the surface of aluminum, which is much faster and thicker than other metal oxide films, thus preventing the corrosion of harmful gases and water in the air and playing a protective role.

2. Although pure aluminum has good corrosion resistance, its poor mechanical strength restricts its application to a certain extent.

Therefore, people add appropriate amount of magnesium, copper, zinc and other metals in aluminum to make all kinds of aluminum alloy.

The high mechanical strength of aluminum alloy greatly enhances its mechanical strength and expands its application range.

Although aluminum alloy has higher mechanical strength, but its corrosion resistance than pure aluminum, may be due to oxidation corrosion.

Therefore, it is necessary to spray aluminum powder to protect aluminum profiles.

Because of its small proportion, easy to process, high mechanical strength, aluminum alloy has been widely used in building doors, Windows, curtain walls and other products for many years.

After powder spraying, the aluminum profile has the advantages of strong corrosion resistance, various colors and good surface texture.

I hope it will be helpful for you to use spraying equipment in the production process of aluminum profile.
