These processes at Technohome are certified according to the Qualicoat system, ensuring compliance with international standards for coating quality. To achieve a high-quality anode-oxide coating, it is crucial to use premium aluminum alloys for the profiles. The profiles manufactured by Technohome are exclusively made from the finest aluminum alloys, guaranteeing excellent results in anodizing.
The anodizing process not only levels and smooths surface roughness but also imparts a non-directional reflective property to sunlight. This technology enables the realization of various design ideas, offering versatility in combining aluminum with other modern or traditional materials for finishing. Anodized profiles boast corrosion resistance, durability against mechanical stress, and an appealing appearance.
In addition to the standard silver anodic coating, Technohome offers profiles with a golden coating and a range of colors from light brown to black. These colors are available in semi-gloss and matte finishes. Customers can choose from different colors and shades according to their technical specifications, including black, gray, bronze, cognac, champagne, gold, and more.
The anodized coating on the aluminum profile offers several advantages:- Provides reliable protection against corrosion.
- Enhances the decorative properties of the profile.
- Increases its durability and wear resistance.
- Ensures environmental friendliness, making it suitable for food storage applications.
- Allows for further processing and customization options.
Anodizing:Anodizing is an electrochemical process that involves creating a thin oxide layer on the surface of aluminum. In this process, the anodized element acts as the anode in an aqueous solution of sulfuric acid. By applying a direct current voltage to the anode, oxygen is released and reacts with the metal, forming a transparent oxide coating. The resulting coating penetrates approximately 2/3 of its thickness into the metal surface while protruding 1/3 above it.
The oxide layer formed through anodizing is significantly thicker than the natural oxide film, providing effective protection against corrosion for aluminum. The porous structure of the anodized coating allows for the addition of desired, long-lasting colors through electrochemical or interference methods, while also providing high resistance to ultraviolet radiation. Anodizing involves applying an oxide anodized coating to the aluminum profile, enhancing its durability and aesthetic appeal.
With the use of modern equipment, we ensure excellent coating quality in the anodizing process. The available anodizing colors include silver (colorless), gold, and bronze. The thickness of the anodized coating can range from 6 microns to 41 microns, providing the desired level of protection and durability.
The anodized layer provides reliable protection to the aluminum material, offering high resistance against corrosion, weather conditions, and abrasion. To put it into perspective, a warranty for anodizing wristwatches often mentions an erosion rate of "1 micron per year." With this in mind, the anodized coating on aluminum parts is typically guaranteed for 19 years, ensuring long-lasting durability and performance.
Anodizing significantly extends the service life of aluminum profiles while maintaining their quality and strength characteristics over time.
The anodizing process for an aluminum profile involves five key operations:- Degreasing the profile.
- Etching.
- Lightening.
- Anodizing.
- Sealing.
Advantages:- Long service life of the structure and product.
- Enhanced product value.
- Resistance to scratches and chips.
- Prevents fading and oxidation.
- Long-lasting preservation of appearance and texture.
- Easy cleaning and maintenance.
