Aluminum coil manufacturers introduce the process of aluminum coil coloring
1. Pretreatment, the use of methods to clean the external surface, the use of physical and chemical methods can, the most important is to make aluminum coil. This is conducive to the complete oxidation, the composition of the oxide film will be fine. Pretreatment can also use some mechanical equipment
2. Anodizing: aluminum coil manufacturers will react with the aluminum coil after treatment to form a fine oxide film
3. Sealing, after anodizing, there will be many film holes on the oxide film. Sealing the hole is to close these film holes and prevent the oxide film from being polluted. This kind of oxide film is transparent and has adsorption, so some metal salts will be accumulated in the hole, so that some original silver white or many other colors can be displayed on the surface
Aluminum coil manufacturer
The aluminum coil is supposed to be put into use. The temperature should not be too hot or too cold under the normal temperature. It is assumed that as the roof, the height should not be less than 10 degrees. Before installation, timely inspection shall be carried out to ensure that there is no appearance of wear and tear on the roof data, so as to ensure normal operation and service life under normal conditions. The bolt head of aluminum coil manufacturer shall be sealed with waterproof material to prevent rainwater from entering and rusting.
The ambient temperature of aluminum coil processing should be above 7 ℃. The gap of processing roller system should be adjusted according to the thickness of aluminum coil, and the foreign matters on the roller surface and support plate should be removed. It is necessary to check whether the paint on both sides of the aluminum coil is peeling off. If the paint is removed, the reason should be found out and the method should be adopted before continuing the processing.
