Alyuminiy oksidi plitasini turli oksidlanish tamoyillariga ko'ra ikki turga bo'lish mumkin, ya'ni anodik alyuminiy plastinka va kimyoviy alyuminiy oksidi plastinka. The so-called anodlangan alyuminiy plate is to place the aluminum plate in the corresponding electrolyte as the anode, muayyan sharoitlarda va tashqi oqim ta'sirida elektroliz, form a thin layer of alumina on its surface, improve the hardness and wear resistance of the aluminum plate and ensure its good heat resistance. Chemical oxidation refers to the process in which some metals react to form oxide film or passive film on the surface of aluminum plate in weak alkaline or weak acid solution.
What are the advantages of anodised aluminum plate?
1. Good processability: after anodising, the aluminum plate has moderate hardness, which can be easily bent and formed, continuous high-speed stamping, which is convenient for direct processing into products without complex surface treatment, greatly shortening the production cycle and reducing the production cost.
2. Yaxshi korroziyaga chidamlilik: anodised aluminum plate with standard thickness oxide film is used indoors for a long time without discoloration, korroziya, oxidation and rust. The anodised aluminum plate with thickened oxide film can be exposed to the sun for a long time without discoloration.
3. Good fire resistance: the surface of anodised aluminum plate is free of paint and any chemical substances, does not burn at 600 ℃, does not produce toxic gas, and meets the requirements of fire protection and environmental protection.
4. Widely used: suitable for metal aluminum ceiling, curtain wall panel, aluminum plastic panel, fire board, honeycomb aluminum panel, aluminum veneer, electrical panel, cabinet panel, furniture panel, va boshqalar.
