Lembaran aluminium anod adalah kepingan aluminium yang diletakkan dalam elektrolit yang sepadan (seperti asid sulfurik, asid kromik, asid oksalik, dan lain-lain.) sebagai anod, dan elektrolisis dilakukan dalam keadaan tertentu dan tindakan arus luar.
Lembaran aluminium anod adalah kepingan aluminium yang diletakkan dalam elektrolit yang sepadan (seperti asid sulfurik, asid kromik, asid oksalik, dan lain-lain.) sebagai anod, dan elektrolisis dilakukan dalam keadaan tertentu dan tindakan arus luar. A dense oxide film is formed on the surface of the aluminum sheet, and the colorless and porous nature of the anodized film is used to dye and protect the aluminum matrix.
Lembaran Aluminium Anodized
A thin layer of aluminum oxide is formed on the oxidized surface of the aluminum sheet, dengan ketebalan 5 kepada 20 mikron, and a hard anodized film can reach 60 kepada 200 mikron.
Akhirnya, it results in aluminum being harder than diamond. It is typically used in harsh environments or applications that require exposure to the elements. The process creates a hard coating that replaces the original substance. Tambahan pula, it won’t flake like regular rust, so aluminum oxide sheets can be used in many applications.
5052 kepingan aluminium has good anodizing performance, and the color difference after anodizing is small.
Anodizing is accomplished by immersing the aluminum into an acid electrolyte bath and passing an electric current through the medium. A cathode is mounted to the inside of the anodizing tank; the aluminum acts as an anode, so that oxygen ions are released from the electrolyte to combine with the aluminum atoms at the surface of the part being anodized. Anodizing is, Oleh itu, a matter of highly controlled oxidation—the enhancement of a naturally occurring phenomenon.
Process Of Anodizing Aluminum Sheet
Cleaning → pretreatment → electrolyte → current and time → anodizing → sealing → cleaning and drying
Pembersihan: Before anodizing, metal parts need to be cleaned to remove surface grease and impurities. The cleaning process is usually carried out with alkaline or acidic solutions.
prarawatan: Metal parts first undergo some pretreatment, such as deburring, grinding or polishing. This can improve the surface finish after anodizing to some extent.
Electrolyte: The metal part is placed in an electrolyte containing an oxidizing agent and other additives. The composition of the electrolyte depends on the metal used and the desired surface treatment.
Current and Time: Make the metal part anodic by adding a direct current to the electrolyte. The current and treatment time are adjusted according to the desired treatment effect.
Anodizing: In the electrolyte, an oxide film is formed on the surface of the metal parts. This process is called anodizing. During this process, the thickness and color of the oxide film depend on the electrolyte and current/time parameters used.
Pengedap: By soaking in hot water or other sealants, the micropores of the oxide film are sealed, thereby enhancing its corrosion resistance and hardness.
Cleaning and drying: Processed parts need to be cleaned and dried to remove excess electrolyte and sealant.
| Oxide film thickness | Chemical oxidation: the oxide film is thin, with a thickness of about 0.5 kepada 4 mikron. Electrochemical oxidation: the oxide film thickness is about 5 kepada 20 mikron. Hard anodizing: the oxide film thickness can reach 60 kepada 200 mikron. |

| Permohonan | Abrasive materials and cutting tools, aluminum parts that require high heat resistance and insulation performance, such as pistons, cylinders, bearings, impellers of hydroelectric equipment, dan lain-lain. |
Anodized aluminum sheet metal is a type of aluminum sheet that has undergone an anodization process. Anodization is an electrochemical process that thickens the natural oxide layer on the surface of aluminum, making it more durable, tahan karat, and able to hold color and dyes. Here are some key features and uses of anodized aluminum sheet metal:
Enhanced Corrosion Resistance: Anodized aluminum has a thicker and more stable oxide layer on its surface, which provides excellent resistance to corrosion and oxidation. This makes it suitable for outdoor and marine applications.
Increased Durability: The anodization process hardens the surface of the aluminum, making it more scratch-resistant and durable. This makes it suitable for applications where the material may encounter wear and tear.
Color Options: Anodized aluminum can be dyed in various colors during the anodization process. This allows for a wide range of color choices for decorative and aesthetic purposes.
Electrical Insulation: Anodized aluminum has good electrical insulation properties, which can be advantageous in certain applications where electrical conductivity needs to be minimized.
Decorative and Architectural Use: Anodized aluminum is commonly used in architectural elements, such as building facades, dinding langsir, and decorative trim, due to its durability and aesthetic appeal.
Consumer Products: It is also used in the production of consumer products like cookware, Peralatan, and electronic enclosures, where its durability and resistance to staining are important.
Ringan: Aluminum itself is a lightweight material, and anodized aluminum maintains this property, making it suitable for applications where weight is a concern.
Anodized Aluminum Sheet Applications
Penyelenggaraan Mudah: Anodized aluminum is relatively easy to clean and maintain, requiring simple cleaning procedures to retain its appearance.
Non-Toxic and Environmentally Friendly: Anodizing is a non-toxic process, and anodized aluminum is considered environmentally friendly because it is durable and long-lasting, reducing the need for frequent replacements.

The price is expensive. Due to the complex process and high technical requirements, the price of anodized aluminum sheet is much higher than that of mill finish aluminum sheet.
Color difference problem
The color difference problem of anodized aluminum sheets is not caused by production technology because the oxidation bath liquid is prepared from a variety of chemical elements. Every time a batch of aluminum materials is oxidized, the chemical composition in the bath liquid changes, so the bath liquid is oxidized and colored with variable values. Aluminum materials always have color differences.
