Aluminum Barrier: An Overview
An aluminum barrier is a versatile and practical product widely used across multiple industries. Here's a detailed introduction to it:
Material Properties
• Lightweight yet Strong: Aluminum has a relatively low density (around 2.7g/cm³). Compared to materials like steel, it's much lighter, making transportation, installation, and handling a breeze. Meanwhile, through alloying and other manufacturing processes, aluminum barriers can gain sufficient strength to withstand certain external impacts.
• High Corrosion Resistance: When exposed to air, aluminum quickly forms a dense aluminum oxide film on its surface. This film acts as a shield, preventing further oxidation of the aluminum. It effectively resists erosion from rain, moisture, chemicals, etc. Even in harsh environments like humid or acidic - alkaline settings, it maintains stable performance over the long term, cutting down on maintenance costs.
• Excellent Processability: Aluminum boasts great ductility and plasticity. It can be shaped into various complex forms and sizes via processes such as extrusion, rolling, and stamping. This allows it to meet diverse appearance and structural needs for aluminum barriers in different scenarios.
Common Types
• Aluminum Sound - Insulation Barriers: Usually composed of an aluminum alloy frame combined with sound - absorbing and sound - insulating materials. By rationally designing the structure and selecting materials like porous fiber ones, they can effectively reflect and absorb sound waves. They're used to reduce the impact of traffic noise (from highways, railways) and industrial noise on the surrounding environment, often installed along highways, railways, and around industrial plants.
• Aluminum Dust - Proof Barriers: Generally made of smooth aluminum plates, formed through special edge - folding and assembly processes. They can block the spread of dust, playing an effective role in reducing air pollution from dust in places like mines, construction sites, and ports.
• Aluminum Electromagnetic Shielding Barriers: The surface of aluminum plates undergoes special treatments, such as metal plating. This gives them good electromagnetic shielding performance, capable of blocking electromagnetic signal interference and protecting the normal operation of electronic devices. They're commonly used in places with high electromagnetic environment requirements, like electronic computer rooms and communication base stations.
Application Fields
• Transportation: Installed along highways, urban expressways, and railway lines, aluminum sound - insulation barriers reduce the impact of vehicle and train noise on nearby residential areas, schools, and hospitals. At bridge and tunnel entrances, aluminum protective barriers are used to ensure traffic safety and provide isolation.
• Industry: Around factory workshops, aluminum dust - proof and sound - insulation barriers reduce dust and noise pollution to the surrounding environment. In the electronics industry, they're used to make electromagnetic shielding barriers, protecting sensitive electronic components from electromagnetic interference.
• Construction: In construction projects that demand both environmental aesthetics and functionality, aluminum barriers can serve as decorative barriers. For example, as landscape isolation barriers in commercial plazas or wall barriers in residential communities, they provide isolation and protection while adding to the aesthetic appeal.
Advantages
• Aesthetic and Durable: Through surface treatments like anodizing, powder coating, and fluorocarbon coating, aluminum barriers can have a wide range of colors and surface textures, enhancing their visual appeal. The treated surfaces also boost corrosion and wear resistance, extending their service life.
• Eco - friendly and Recyclable: Aluminum is a recyclable metal. When an aluminum barrier reaches the end of its service life, it can be recycled and reprocessed into various aluminum products. This not only saves resources but also reduces environmental pollution from waste.
