Во-вторых, вы должны выбрать чистый алюминий или сплав алюминия.?

There are many anodic oxidations for aluminum alloys, which can be used in daily life. Because of the characteristics of this process, a hard protective layer is produced on the surface of aluminum parts, which can be used to produce kitchen utensils and other daily necessities. тем не мение, the anodizing effect of cast aluminum is not good, the surface is not good, and it can only be black. The aluminum alloy profile should be better, the following is a brief introduction to the method of aluminum plate oxidation treatment.

In the past ten years, my country’s aluminum oxidation and coloring technology has developed rapidly. Many factories have adopted new technology and have accumulated rich experience in actual production. There are many mature and developing processes for anodizing aluminum and its alloys, and suitable processes can be selected according to actual production needs.

Before choosing an oxidation process, you should understand the material of aluminum or aluminum alloy. Because the quality of the material and the difference in the composition will directly affect the quality of aluminum products after anodization.

Например, if there are bubbles, scratches, Алюминиевый лист h32 – задняя панель ЖК-телевизора, roughness and other defects on the aluminum surface, all the defects will still be revealed after anodizing. The alloy composition also has a direct effect on the surface appearance after anodization.

Например, an aluminum alloy containing 1 к 2% manganese will be brownish-blue after oxidation. As the manganese content in the aluminum material increases, the surface color after oxidation will change from brown-blue to dark brown.

Aluminum alloy with 0.6 к 1.5% silicon content is gray after oxidation, and white gray when silicon content is 3 к 6%.

Zinc-containing products are opalescent, chromium-containing products have an uneven tone of golden to gray, and nickel-containing products are light yellow.

Вообще говоря, only aluminum with magnesium and titanium content greater than 5% contains gold, and after oxidation, a colorless, transparent, bright and clean appearance can be obtained.
