The working cycle lasts 30 minutes. After the desired color is achieved, the product is removed from the container and washed first with warm and then cold water.
widespread. Many methods of applying an oxide film have been developed, including color coating. The decorative purpose of oxidation is especially popular.
The coating technology is not very complicated. If desired, aluminum oxidation can be carried out at home - this will not require large expenses.
Anodizing is a universal technology that can be used both chinese overseas america data preparatory work before painting and as independent protection of the metal surface. In addition, the treated elements can be given additional visual effects.
Anodizing of aluminum
Recently, structures and products made of anodized (abbreviated anod. is often used) aluminum profiles are increasingly in demand. Due to their beautiful appearance and advantages, products made of anodized aluminum are used in various areas of design and construction.
The oxide (anodic) film cannot protect the metal from the destructive effects of corrosion due to its high porosity, small thickness and low mechanical strength.
The most proven and reliable method of protecting metal and its alloys from harmful corrosion is considered to be the process of anodic oxidation in sulfuric acid solutions. This process is also called aluminum anodizing. The oxide layer, which is obtained by electrolytic method, has a density 200-2000 times greater than that of natural oxide films. Compared to other coating methods (varnishing, painting, covering the surface with polymer films), aluminum anodizing in black or any other color eliminates the problems of peeling and under-film corrosion.
Anodizing of aluminum has become the most
