What is Aluminium powder coating?
Powder coating is a system of protection of the aluminum that consists in the application of a coating, either liquid or powder, on the surface of the metal.
Where is aluminum powder?
In addition to its use in cosmetics and personal care products, it can be found in air, water, soil and food. Aluminum is widely used in many applications including cooking utensils. Because Aluminum Powder comes from the earth it may contain trace amounts of heavy metals.
How do you manufacture Aluminium powder?
For the production of aluminium powder, there are several processes, one can use any of them. The metal is melted in furnaces and the temperature maintained is around 720O to 760OC. Atomised Aluminium is produced by blasting the stream of molten Aluminium into small particles by air jet.
Why does aluminum powder explode?
Finer particles burn readily when their ignition point is reached, and tend to ignite the coarser particles as well. In the case of aluminum, an explosion can result if ignition occurs while the particles are suspended in air as a dust cloud, since the burning extends from one particle to another with extreme speed.
How do you make aluminium powder coating?
How the Powder Coating Process Works
- 1) Pre-treat the Aluminum Surface. The pre-treatment process involves removing dust, grease, and any other foreign particles.
- 2) Apply Powder to the Extrusions.
- 3) Heat Aluminum Profiles in the Curing Oven.
- 4) Cool the Extrusions.
