What effect anodized disposal

Aluminum and alloys after anodizing equipment disposal , you can make a layer made ​​of aluminum and its alloys look much more than the natural oxide film thickness fine film . This layer of oxide film and then the whole story off manually dispose of non- crystalline oxide film into a crystalline oxide film , the pore is also closed , thus making the same metallic gloss appearance can be durable , corrosion function, the mechanical strength has increased , embellishment can be achieved by staining appearance . Because aluminum and its alloy products after anodizing the whole story has many features, so the Anodized Aluminum process in aluminum look wider use of disposal . Use in industry can be broadly divided into the following categories:

( 1) to avoid corrosion products : Because the anodized film obtained by the closure of the appropriate disposal of the whole story in the atmosphere has good stability . Whether from the sulfuric acid solution , oxalic acid or chromic acid solution obtained in the normal process of the oxide film , the corrosion is a very good function , such as household aluminum pan , pot, washing interior and so on. Chromic acid oxidation method for aluminum welding parts together and riveting pieces .

( 2 ) protection - embellishment : high transparency in the obtained oxide film , the oxide film can be adsorbed with a variety of organic dyes or inorganic pigments characteristics , the oxide film can be obtained in a variety of light colors and pictures handsome , and in recent years not the presentation of new technology , such as less oxidized repeated once colored fireworks picture , wood picture , oxidative handling offset printing , ceramic oxide , so that even more handsome aluminum pleasing appearance , this layer of film is both colorful decorative layer , but also resists , such as lighters , fountain pens and crafts.
