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. যাহোক, 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.
উদাহরণ স্বরূপ, if there are bubbles, 3xx অ্যালুমিনিয়াম শীট 3xxx এর সাথে সম্পর্কিত, শুধুমাত্র কঠোর পরিশ্রমের মাধ্যমেই রাষ্ট্রের প্রয়োজনীয় শক্তি অর্জন করা যায়, 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.
উদাহরণ স্বরূপ, an aluminum alloy containing 1 প্রতি 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 প্রতি 1.5% silicon content is gray after oxidation, and white gray when silicon content is 3 প্রতি 6%.
Zinc-containing products are opalescent, chromium-containing products have an uneven tone of golden to gray, and nickel-containing products are light yellow.
সাধারণভাবে বলতে, 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.
