As a sound absorption and sound insulation material, 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 rooms, machinery and equipment, and outdoor construction sites, and solves many limitations of the 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. So it is widely used in many fields. Foamed aluminum has a wide range of applications. Its low density, high rigidity, sound insulation, heat insulation, fire resistance, energy absorption, 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.
The foamed aluminum "sandwich" structure has the characteristics of light weight and high rigidity, and can be used as an excellent structural material. For example, when used as a structural part of an automobile, the weight is only half of the steel structure, and the stiffness is increased by 10 times. It is reported that about 20% of automobile structural parts can adopt this structure. Foamed aluminum is a new type of construction and decoration material. It has the advantages of light weight, high specific rigidity, beautiful appearance, non-combustion, etc., and has the characteristics of sound absorption, heat insulation, and electromagnetic shielding. Therefore, foamed aluminum can be widely used in the architectural decoration of shopping malls, hotels, stadiums and other venues.
Foamed aluminum can be cut, drilled, cemented, and extruded with abrasive tools to be made into various shapes, and can be surface treated like ordinary aluminum, and it can also form a large-size lightweight and high-rigidity board; because of its lightness , The foamed aluminum material can be easily installed in high places without any mechanical lifting equipment, which also allows the direct use of adhesives to stick to the ceiling and wall.
