Definitions
- the invention relates to a method for producing an article having an aseptic surface, in which method on an aluminum or aluminum alloy article by anodization creates a porous oxide layer and subsequently from an at least one salt of a metal having antimicrobial activity containing electrolytes electrochemically metal with antimicrobial Effect is embedded in the pores of the oxide layer.
- EP-A-1 207 220 and US-A-6 168 869 it is known to anodize articles of aluminum or an aluminum alloy and metals with antimicrobial action, such. As silver, copper or zinc, to embed in the pores of anodic oxide layer.
- the invention is based on the object of providing a method of the type called to create a way by which the antimicrobial effect of the embedded in the pores of the oxide layer metals can be further improved.
- the article is immersed in a pickling solution with the oxide layer filled with metal having antimicrobial action, and the oxide layer is uniformly partially removed on its surface.
- silver is preferably used.
- copper zinc or a mixture of said metals have an antimicrobial effect.
- the pickling treatment attacks the oxide layer on the surface. Only a small part of the surface should be removed evenly. The embedded in the pores of the oxide layer metal is not affected by this process and protrudes like a needle out of the surface after pickling. The aseptic effect is thereby enhanced.
- the oxide layer is evenly removed by an amount between about 0.01 microns and at most about 1 micron.
- the anodization of the oxide layer in a sulfuric acid electrolyte to an oxide thickness of 5 to 25 microns or in a sulfuric acid / oxalic acid electrolyte to an oxide thickness of 15 to 70 microns performed.
- the partial removal of the oxide layer can in an alkaline pickling solution, for example in an aqueous solution of sodium hydroxide or sodium carbonate, or in an acidic pickling solution, for. B. in an aqueous solution of nitric acid, or in an acid Mischbeizants, for example in an aqueous solution of sulfuric acid and hydrofluoric acid, are performed.
- a preferred field of application of the articles produced by the method according to the invention lies in their use as components of devices in the areas of increased risk of contamination with pathogens, in particular in the medical field, such. In hospitals and doctors' surgeries, as well as in public transport.
- the articles Prior to anodizing, the articles are degreased, pickled and pickled by conventional methods.
- the degreasing takes place z. B. with an alkaline cleaner containing borates, carbonates, phosphates and nonionic surfactants at a temperature of 50-70 0 C and a dipping time of 10-20 minutes.
- the pickling takes place for.
- the Dekapieren z. B. with an acidic, salts of inorganic acids and inorganic acids containing pickling at a temperature of about 20 0 C and a dipping time of 5-10 minutes. After each step, the objects are thoroughly rinsed with deionized water.
- the articles with the silver embedded in the pores of the anodic oxide layer are again rinsed thoroughly with deionized water and subsequently immersed in a pickling solution in order to remove the oxide layer evenly on its surface in a uniform manner.
- sealing 10-50 g / L sulfuric acid + 1-10g / L hydrofluoric acid bath temperature: 20-40 0 C pickling time: 1-10 min
- a densification of the oxide layer known as sealing can be carried out.
- the task of the sealing or sealing process is to close the pores in which the silver or other metals are embedded.
- the densification of the oxide layers may e.g. be carried out with the following known sealing methods:
- the compression can be done in a spray or dip.
- the densification of the oxide layers can be carried out before or after the partial removal of the oxide layer in the pickling solution.
