Closed (Not fully open) Cell of Aluminum Foam (Al foam)

1, the high-tech, new foam aluminum, good sound absorption performance, stable acoustic performance, clean, good light, beautiful, fire, afraid of water, physical properties, easy processing, and use it to make various forms of suction sound body, muffler, sound structure, sound barriers, silencers room, acoustic enclosures, etc., can be directly facing the noise source, without any protective panels and other sound-absorbing fillers.

2, with excellent acoustic performance: average absorption coefficient ≥0.60 (125-4000Hz frequency range, Tongji University Acoustics determination); both board and spray gray water absorption properties do not change after the excellent acoustic performance.

3, foam aluminum from aluminum die-casting, the damage can all be recycled, is currently the only cause secondary pollution of the environment is not new green tech products.

4, foam aluminum is currently no fibrous material in the world front and replacement products will not cause aging like after a similar fiberglass, mineral wool, rock wool, etc. by the high temperature environment into the sun and rain and dust flying cause secondary pollution of the atmosphere.

5, the corresponding non-flammable fire, weather resistance, corrosion resistance, aging resistance with metallic aluminum, and can withstand wind, rain, sun, is a Class A non-combustible products.

6, can be coated with different coating colors, beautiful, coating after repeated dilute spray drying process, so even in the wind and sun conditions, it will not fade.

7, with good electromagnetic shielding performance.

8, aluminum foam acoustic panels can be cut, any bonding, riveting, plug, easy to install.

9, the foam can be made either of aluminum absorber in various forms, can be combined into various forms of sound absorption, sound body.

10, the surface easy to clean, easy maintenance.

for concert halls, theaters, recording studio, studio, dance halls, stadiums, subway stations, lounges, waiting rooms, hotel lobbies, shopping malls, showrooms, office lobby, telegraph room, computer room and other places play a role in controlling sound reverberation time.

pipe muffler, silencer elbow, plenum, especially for clean workshop, food production plants, pharmaceutical plants, precision instrument manufacturing workshop, laboratory, wards, operating rooms, restaurant dining, ship cabin, auxiliary engine room, cabin and other places of air conditioning, ventilation equipment to play the role of noise silencer.

play the role of sound-absorbing sound barrier in urban light rail, elevated road, traffic roads, highways, railways, overpasses, cooling towers, outdoor high-voltage substations, concrete mixing field and other places.

In diesel engines, generators, motors, internal combustion engines, freezers, air compressors, aircraft, trains, cars, ships, boilers, hammer equipment, fans and other equipment, can be sound absorption, sound insulation, noise reduction effect.

Main Aperture: 0.9mm, 1.6mm, 2.5mm in three sizes, common specifications for 1.6mm aperture.

average absorption coefficient (125-4000Hz frequency range measured)

Noise Reduction Coefficient NRC "0.64 (250-2000Hz frequency range measured)

Air Sound weighted sound reduction Rw 28.0dB (ie noise index la)

The average amount of noise Ra 24.5dB (125-4000Hz frequency range measured)

Note: The measured acoustic board specifications:

sound-absorbing panels (foam aluminum) thickness of 8mm, air layer thickness 100mm, backplane (color plate) thickness of 0.5mm, assembled structure.
