Aluminium Brightening and Anodising

Degreasing

Any and all material whose surface is to undergo treatment must be clean and free from dirt, particles, oils, or any other element. To meet this requirement, DEGREASING processes are used.

Various factors must be taken into consideration when choosing a degreaser: the dirt type, the material, the applied surface finish, or the next step in the process.

Degreasers are usually differentiated as acidic, alkaline, or inhibited alkaline formulations.

Desmutting

The process of desmutting or deoxidizing is referred to with various names, including neutralising. This process eliminates the surface metals present that appeared during the preparation processes, while also adjusting the pH of the pieces to an appropriate level prior to the anodising phase.

Anodising

During the anodisation process, a film of aluminium oxide is added to the surface. This artificial oxide layer provides various benefits, including protection against corrosion and the ability to apply colouring processes.

Colouring

One of the best aesthetic properties of anodised aluminium is that it can undergo a colouring process. This process is possible via various methods: organic colouring, inorganic colouring, electrolytic colouring or interference colouring.

Organic and inorganic colouring allow for a wider range of colours and hues that aesthetically enhance the finish of the pieces. Barcelonesa is the exclusive and official distributor of the product ranges from Omya and Clariant, leading companies with a long history of supplying high-quality colourants for the anodising industry. This agreement enables us to distribute their products in Spain, Portugal and North Africa.

Sealing

Sealing is the process of closing the pores created during the anodising phase. Properly sealing the pores guarantees the adherence of the properties obtained throughout the entire process.

The different sealing processes can be differentiated by the temperatures employed: low, medium or high temperature.
