China's production of aluminum equipment aluminum alloy building profile products in level, type has been comparable with foreign countries.Product categories can be divided into: anodized coloring profiles, electrophoretic painted profiles, powder sprayed profiles, fluorocarbon paint sprayed profiles, thermal insulation profiles.Aluminum profile, is the aluminum bar through the hot melt, extrusion, and thus the shape of different sections of aluminum materials.The production process of aluminum profile mainly includes three processes: casting, extrusion and coloring.Among them, coloring mainly includes: oxidation, electrophoresis coating, fluorocarbon spraying, powder spraying, wood grain transfer and other processes.The following exhibition yao coating for you to introduce the aluminum profile in the manufacturing process why to use aluminum profile spraying equipment.
Aluminum is a light metal with silver-white luster, and its corrosion resistance has the following two characteristics:
1. The higher the purity, the better the corrosion resistance. As is known to all, pure aluminum interacts with oxygen in the air and produces a very thin and dense natural oxidation film on the surface of aluminum, which is faster and thicker than other metal oxidation film, thus preventing the corrosion of harmful gas and water in the air and playing a protective role;
2. The corrosion resistance of pure aluminum is good, but the poor mechanical strength, which to a certain extent, restricted the application of aluminum, therefore, adding the right amount of people in the aluminum magnesium, copper, zinc and other metals, made into various types of aluminum alloy, aluminum alloy of high mechanical strength, greatly improve the mechanical strength of aluminium, greatly expand the application range, aluminum alloy has high mechanical strength, but poor corrosion resistance than pure aluminum, so it is possible because of oxidation and corrosion.This needs to carry on the aluminum profile to spray the powder to the aluminum alloy profile to try to protect, the aluminum alloy with its specific gravity small, easy processing, mechanical strength and other characteristics over the years widely used in the building doors and Windows, curtain wall and other products.
After powder coating, aluminum profile has high corrosion resistance, color diversity, good surface texture and many other advantages, about the aluminum profile in the manufacturing process why to use coating equipment, we hope to help you, if you need spraying equipment please contact us.
