Sound-absorbing and sound-insulating materials: Aluminum foam can be used for urban light rail, elevated highways, underground tunnels, noise control of mechanical equipment, and improvement of acoustic rooms, multi-functional halls and other indoor sound effects. Sound-absorbing foamed aluminum is pasted on concrete or steel structures, and erected on both sides of viaducts and light rails as large sound-absorbing walls, which can reduce urban traffic noise. Sound-insulating aluminum foam can be used for noise isolation in factory computer rooms, machinery and equipment, and outdoor construction sites, solving many limitations of widely used sound-absorbing materials such as glass wool and asbestos 1. Rail transit industry. Such as heat insulation and sound insulation, energy absorption and fire prevention, and anti-virus components in carriages and containers. 2. Environmental protection fields in urban construction, such as: soundproof screens; 3. Automobile manufacturing. Such as: bumpers and mufflers. 4. Energy-saving buildings. Such as: thermal insulation walls and fire insulation doors, energy-saving mobile houses. 5. Military industry, sound-absorbing and anti-magnetic components, such as: sandwich panels for tanks and submarine shells. 6. The heat and sound insulation, shockproof and energy absorbing elements of other machinery manufacturing, aviation industry and other products can be made of foamed aluminum materials.
