Anodized aluminum veneer is an aluminum sheet obtained by anodizing process, which has many excellent properties and application scenarios. The following is a detailed introduction to anodized aluminum veneer:
1. Definition and principles
Anodized aluminum veneer is to place the aluminum veneer in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, and electrolyze it under specific conditions and applied current, so that a thick and dense layer of aluminum oxide naturally grows on the aluminum surface. Aluminum oxide protective film. This oxide film is not an additional layer, but is tightly combined with the aluminum plate and will not peel off.
2. Performance characteristics
1). Strong stain resistance: The surface of anodized aluminum veneer is easy to clean, not easy to leave fingerprints, easy to clean, and does not produce corrosion spots.
2). Good weather resistance: Anodized aluminum veneer with standard thickness oxide film (3μm) will not change color, corrode, oxidize, or rust for a long time when used indoors. Anodized aluminum veneer with thickened oxide film (10μm) can be used Outdoors, it is not easy to change color even if exposed to sunlight for a long time.
3). Strong metallic feel: The anodized aluminum veneer has high surface hardness and good scratch resistance. The surface is not covered with paint, retaining the metallic color of the aluminum plate and highlighting the modern metallic feel.
4). High fire resistance: As a pure metal product, the surface of anodized aluminum veneer has no paint or any chemicals, does not burn at a high temperature of 600 degrees, does not produce toxic gases, and meets the requirements of fire protection and environmental protection.
5). Good processability: Anodized aluminum veneer is highly decorative and has moderate hardness. It can be easily bent and formed, and can be continuously stamped at high speed to facilitate direct processing into products without complex surface treatment.
3. Application scenarios
Anodized aluminum veneer is widely used in various fields due to its good performance:
1). Architectural decoration: Used as indoor and outdoor building materials, such as facades, curtain walls, ceilings, partitions, handrails, etc.
2). Electronic field: Widely used in electronic devices, such as integrated circuits, capacitors, resistors, semiconductors, etc.
3). Machinery manufacturing: used to manufacture parts for automobiles, airplanes, trains and other vehicles of transportation.
4). Household items: Manufacture various household items, such as kitchen utensils, lighting, furniture, decorations, etc.
5). Medical devices: used to manufacture medical devices, such as surgical instruments, medical equipment, etc.
6). Aerospace: Used to manufacture aerospace devices, such as missiles, satellites, etc.
4. Production process flow
The production process of anodized aluminum veneer mainly includes cleaning, pickling, anodizing, coloring, sealing and other steps:
1). Cleaning: Clean oil, dust and other impurities on the surface of the aluminum plate to ensure that the surface is clean.
2). Pickling: Soak the aluminum plate in an acidic solution for pickling treatment to remove oxide scale, oxides, etc. on the surface of the aluminum plate.
3). Anodization: Put the aluminum plate into an anodic treatment tank, apply DC power supply to carry out electrolysis reaction, and form an oxide film on the surface of the aluminum plate.
4). Coloring: Electrolytic coloring or chemical coloring treatment is performed according to needs to give the aluminum plate different colors.
5). Sealing: Put the anodized or colored aluminum plate into the sealing solution to seal the micropores in the anodized layer to improve the corrosion resistance and sealing performance of the aluminum plate.
To sum up, anodized aluminum veneer plays an important role in many fields such as construction, electronics, machinery, and home furnishing with its unique performance and wide application scenarios.
