Anyone who touches the aluminium peroxide board knows that the traditional alumina board will have color difference more or less, which is unavoidable, but also a major drawback of the traditional alumina board. For this reason, Taialuminium has carried out technological innovation and put into production a continuous roll-on-roll anodic oxidation project. After eight years of market verification, the anodic oxidation process has effectively controlled the color difference.
The factors affecting the color difference of alumina plate are as follows:
1. Raw material factors; the color difference caused by raw materials is more reflected between aluminium coil and aluminium coil rolled at different times; the reason is that the original gloss reflection of raw material panel is deviated, which is due to the mechanical grain of raw material after rolling, the thickness of material grain, and the smoothness of material affecting gloss reflectance.
2. Influences of oxidation coloring film forming process, control factors of color matching process, errors caused by different batches of color matching in coloring process and other factors.
3. The glossiness of multi-layer color is not affected by the glossiness of different layers; the color difference between product plate and plate, batch and batch is easy to be caused by the glossiness deviation caused by secondary oxidation, multiple oxidation and multiple oxidation of printed products, their pre-and post-treatment, and multiple film-forming process changes.
Influenced by many factors, the traditional oxidation process can not effectively control the color difference.
