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 effect (also known as anodizing).

Reaction mechanism

The anode effect is a characteristic phenomenon of molten salt electrolysis, and the performance of electrolytic aluminum production is still obvious. When the anode effect occurs during production, the cell voltage 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, destroying the smooth power supply of the entire electrolysis series. In terms of treatment methods, there are at least two kinds: extinguishing with effect bars (wooden rods), or lowering the anode, and increasing the amount of aluminum oxide to achieve the purpose of extinguishing the anode effect. No better treatment has been found.

The anode 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 anode carbon to produce carbon fluoride. When the carbon fluoride decomposes again Precipitated fine carbon particles, which are attached to the surface of the anode, prevent the electrolyte from contacting with the anode, so that the electrolyte cannot wet the anode well, just like water cannot wet the oiled surface, so that the electrolyte-anode forms a For a gas film with poor conductivity, the anode overvoltage increases, causing an anode effect. When new alumina is added, oxygen is precipitated on the anode again. Oxygen reacts with the carbon powder to gradually make the anode surface quieter, the resistance decreases, and the electrolysis process tends to normal.
