Aluminum Foam Fire-Retardant And Noise-Proof

Product Description

Aluminum foam is a new type of light metal material produced by pure aluminum foam, with low density and high specific strength, it has many excellent properties such as sound absorption and insulation, energy-absorbing cushioning, flame retardant and explosion-proof, and it is widely used in cutting-edge equipment fields such as military and aerospace industry, rail transportation, shipbuilding and so on. Because of its unique metal texture is now favored by many designers, applied to the building decoration industry, to create a different sense of technology.

Product Parameters

Pore characteristics and bulk density

Main pore size: 0.9mm, 1.6mm, 2.5mm three specifications, commonly used specifications for 1.6mm pore size.

Porosity: 60-80% (68-78% for 1.6mm pore size)

Through-hole ratio: 85-95% (90-95% at 1.6mm aperture)

Bulk density: 0.5-1.10g/cm3 (0.60-0.85g/cm3 for 1.6mm aperture)

The main characteristics of aluminum foam acoustic panel:

1. High-tech, new foam aluminum panels, sound-absorbing performance, stable acoustic performance, non-polluting, lightweight, beautiful, fireproof, not afraid of water, good physical properties, easy to process, with which it is made into a variety of forms of sound-absorbing body, muffler, acoustic structure, sound barriers, muffler room, acoustic enclosures, etc., can be directly in the face of the noise source, without the need for any protective panels and other sound-absorbing filler.

2. It has excellent acoustic performance: the average sound absorption coefficient is ≥0.60 (125-4000Hz frequency range, determined by Acoustics Institute of Tongji University); at the same time, it has the excellent acoustic performance that the acoustic performance does not change after water spraying and ash spraying of the board.

3. Foam aluminum plate by aluminum alloy die-casting molding, broken, can be recycled in its entirety, is currently not a secondary pollution of the environment caused by the green environmental protection of new high-tech products.

4. Aluminum foam board is currently the world's non-fiber materials, cutting-edge and replacement products, will not be similar to glass fiber, mineral wool, rock wool, etc. by the sun, rain, high temperature and other environments caused by the aging of the dust into the dispersal of the atmospheric environment caused by secondary pollution.

5. It has the corresponding fireproof and non-combustibility, weather resistance, corrosion resistance, anti-aging properties of metal aluminum, and can withstand the wind, rain and sun, and is a Class A non-combustible product.

6. It can be coated with different color coatings, which is beautiful, and the coating has been thinned and sprayed and dried for many times, so it will not fade even under the conditions of wind and sunshine.

7. It has good electromagnetic shielding performance.

8. Aluminum foam acoustic panels can be sawed, can be arbitrarily bonded, riveted, inserted, easy to install.

9. Aluminum foam panels can be made into various forms of sound-absorbing body, but also can be combined into various forms of sound-absorbing, sound insulation body.

10. The surface is easy to clean, easy maintenance.

Aluminum foam sound-absorbing board application scope

1. Used in concert halls, theaters, recording studios, studios, dance halls, gymnasiums, subway stations, waiting halls, waiting rooms, hotel lobbies, large shopping malls, exhibition halls, office halls, newspaper rooms, computer rooms and other places to control the role of sound reverberation time.

2. It is especially suitable for air-conditioning and ventilation equipments in clean workshops, food production workshops, pharmaceutical factories, precision instrument manufacturing workshops, laboratories, wards, operating rooms, restaurants and canteens, ship cabins, auxiliary engine cabins, passenger cabins, etc. It plays a role of noise reduction and muffling.

3. It plays the role of sound-absorbing and sound-insulating barrier in urban light rail, elevated roads, traffic arteries, highways, railroads, overpasses, cooling towers, open-air high-voltage substations, concrete mixing yards and other places.

4. In diesel engines, generators, motors, internal combustion engines, freezers, air compressors, airplanes, trains, automobiles, ships, boilers, forging hammer equipment, fans and other equipment, sound absorption, sound insulation, muffling effect.
