Ⅱ: The Process Of Oxidation Of Aluminum Plate.
Ⅱ-A: Anodises Aluminium In Colour And Gloss
Our colour range includes 1 blue tone. We do not use pigments, but metals to obtain the blue colour. By depositing metals in the pores and then electrochemically modify the pores (interference anodising), we can obtain the colour dark blue. Blue anodising is 100% UV resistant and will remain sparkling for a long time.
Ⅱ-B: Basic Of Anodizing Process
Before discussing the various anodized aluminum color or how to color aluminum, we should prickle your brain on what the process is all about. Unless you have a science background or are already deep-rooted in the process, it won’t be surprising that you wonder the aluminum anodizing process. Therefore, in this section, we will summarize the basic things about the process.
Aluminum anodizing is an electrochemical process in which aluminum products’ surfaces are coated using a wear-resistant oxide layer. Therefore, the products exhibit properties that improve quality and aesthetics. For example, they are durable, resistant to wear and corrosion. They also have this beautiful feel which fulfills the aesthetic requirement of most users.
Anodizing is an electrochemical cell reaction with the aluminum part acting as the anode, the cathode being an inert material, and an acidic electrolyte. Below are the electrochemical reactions at the electrode:
Anode: 2Al + 3H2O = Al2O3 + 6H+ + 6e-
Cathode: 6H+ + 6e- = 3H2
Resulting anodizing reaction: 2Al + 3H2O = Al2O3 + 3H2
Ⅱ-C: Anodizing Colors Of Aluminium Sheet
Anodizing colors are different from the colors of other techniques such as powder coating or paint. In terms of achieving color consistency, there are difficulties due to the many variables involved in anodization.
Anodizing Colors of aluminium sheet
While the anodizing process is open to all colors of the rainbows, the anodized aluminum colors used to depend heavily on many factors such as size, grade, finish tapes. Below are the steps to take on how to color aluminum products using an anodizing process.
