 What is anodized aluminum sheet

Do you know anodized aluminum sheet plate comes? Anodized aluminum plate is a type of corrosion-resistant and oxidation-resistant aluminum plate formed after the aluminum plate is oxidized. By means of surface oxidation, a dense aluminum oxide film is formed on the surface of the aluminum plate, and the thickness of the oxide plate film is about 5 μm-20 μm. The oxidized aluminum plate has a hard anodized film as high as 50μm-200μm.

This protective film can improve the metal hardness and wear resistance of the original aluminum plate, and the surface can withstand a pressure of 200kg-500kg per square centimeter. At the same time, the thermal melting point of the oxide film of the aluminum plate is as high as 2330K, which greatly enhances the heating capacity of the aluminum plate.

 Features of anodize finish aluminum sheets

1. Anodized aluminum sheet front panel is very glorious of the anodized aluminum sheet which can be make the products more and more beautiful.
2. Anodized aluminum sheet can save so much time and save so many proceeds from the anodized aluminum sheets.
3. After anodized , the products is very clean also antifinger for the aluminum coil.
4. Coloured anodized aluminum sheet can be used for so many industries such as the kitchens, airplanes, constructions,  electronic, packings etc
5. After anodized, it will be different kinds surface and different colors for choosing.
6. Different surface for the anodized aluminum sheet, with different usage.

 Anodized aluminum veneer production process

The process of anodized aluminum veneer is different from the ordinary painting process. It electrolyzes the conductive acid electrolyte through the electric current to oxidize the aluminum metal surface that constitutes the anode, and naturally grow a thick and dense aluminum oxide protection layer on the aluminum surface. Film, this oxide film is not an additional layer and will not peel off.

Film, this oxide film is not an additional layer and will not peel off. The oxide film is transparent and colorless, and the microcrystalline structure is hexagonal honeycomb. It can not only use the natural color of aluminum to highlight the strong metallic feeling, but also uniformly color the micropores to give the curtain wall brilliant colors, which greatly broadens the application horizon.

Performance: Standard-thickness oxide film (3um) anodized aluminum veneer does not change color, corrosion, oxidation, and rust for long-term indoor use. The anodizes aluminum veneer with thick oxide film (10um) can be used outdoors, and it can be exposed to sunlight for a long time without changing its color.

 Parameters of anodised aluminum sheet

 Type of anodised aluminum sheet

single side or both sides

Anodized aluminum refers to a layer of dense aluminum oxide coated on the surface of aluminum and aluminum alloys. In order to prevent further oxidation, its chemical properties are the same as aluminum oxide. But unlike ordinary oxide films, anodized aluminum can be dyed with electrolytic coloring.

The preparation principle of anodized aluminum is the anode oxidized effect (also known as anodizing).

 How is the aluminum plate oxidized?

The anodized effect is a unique phenomenon of molten salt electrolysis, and the performance of electrolytic aluminum production is still obvious. When the anodized effect occurs in production, the voltage of the electrolytic cell rises sharply, reaching 20-50V, sometimes even higher. Its occurrence has a great impact on the entire electrolysis series, reducing the current efficiency, affecting the technical indicators of electrolysis, and reducing the output and quality of aluminum, and destroying the smooth power supply of the entire electrolysis series. In terms of processing methods, nothing but

There are two kinds: using an effect rod (wooden rod) to extinguish, or lower the anodized, and increase the amount of alumina to achieve the purpose of extinguishing the anodized effect. No better treatment has been found.

The anodized effect occurs because the oxygen-containing ions in the electrolyte gradually decrease with the progress of the electrolysis process. When it reaches a certain level, there will be fluorine precipitation and interact with the anodized carbon to produce carbon fluoride. When the fluoride of carbon decomposes again, Precipitated fine carbon particles, which are attached to the surface of the anodized, prevent the electrolyte from contacting with the anodized, make the electrolyte not wet the anodized well, just like water can not wet the oiled surface, so that the electrolyte-anode form a For a gas film with poor conductivity, the anodized overvoltage increases, causing an anode effect. When new alumina is added, oxygen is precipitated on the anodized, and the oxygen reacts with the carbon powder, gradually making the anodized surface quiet, the resistance decreases, and the electrolysis process tends to normal.

 Anodized aluminum sheet production process editing

1. Mechanical polishing;

2. Chemical treatment removes the copper component on the surface of certain alloys;

3. Cleaning and degreasing (for the anodized parts, if re-anodization is required, the original anodized surface layer is removed with alkali or special agent)

4. Put it in dilute sulfuric acid as an anode to conduct electricity to generate a surface oxide layer (it is porous and is a white translucent film);

5. Dyeing;

6. Fix (heat or close the pores of the surface oxide layer with chromate solution).
