Foamed aluminum can be used for noise control of urban light rails, elevated highways, underground tunnels, mechanical equipment, and improvement of acoustic rooms, multi-function halls and other indoor sound effects. The sound-absorbing foam aluminum is glued to the concrete or steel structure and erected on both sides of viaducts and light rails as large-scale sound-absorbing walls, which can reduce urban traffic noise.
Sound insulation foamed aluminum can be used for noise isolation in factory computer rooms, machinery and equipment, and outdoor construction sites, and solves many limitations of the currently widely used sound-absorbing materials such as glass wool and asbestos. Foamed aluminum can design the required comprehensive properties by changing its density and pore structure. This is the charm of this unique material. Therefore, it is widely used in many fields:
① Aluminum foam has a wide range of applications. The low density, high rigidity, sound insulation, heat insulation, fire resistance, energy absorption performance and non-toxic gas when heated are widely used in the rail transit industry. Such as the heat and sound insulation, energy absorption, fire prevention, and anti-virus components in the carriage and container.
② Using the low density, high rigidity, and low thermal conductivity of foamed aluminum, it is widely used in energy-saving buildings, such as: heat-insulating walls, fire-proof and heat-insulating doors, and energy-saving mobile houses.
③ Using the sound insulation, sound absorption and energy absorption properties of foamed aluminum, it is used in the environmental protection field in urban construction, such as: sound insulation screen; automobile manufacturing is used in energy absorption and sound absorption components, such as: bumpers and silencers.
④ The heat-insulating, sound-proof, shock-proof and energy-absorbing components of other machinery manufacturing, aviation industry and other products can all be made of foamed aluminum materials.
⑤ It can be used in the military industry, sound-absorbing and anti-magnetic parts, such as the shell sandwich panels of tanks and submarines.
