Applications of Foam Aluminum Profile (2)

C. Needs in the construction

1. The sound-absorbing lining of building

The sound absorption lining made of foam aluminum profile (thickness 10mm) was used in noise-producing places, such as recording studio, sound room, concert hall, conference hall, sports venues, etc. to reduce noise, and there are about 20-40mm thick Cavity behind foam aluminum sound lining, which make a better effect.

2. The sound absorption wall in the swimming wall

As the swimming pool humidity is very heavy, the sound absorption capacity of ordinary sound-absorbing material will greatly reduce when the material gets wet. Natatorium noise reduction is a long and difficult problem in the construction industry. Perforated foam aluminum sound absorption board has high sound absorption, so in humid environment, the sound absorption rate will not reduced. Foam aluminum sound absorber is 10mm thick, cavity behind is about 20mm thick.

3. The foam aluminum curtain in high building

For curtain wall panels in high-rise building, the foam aluminum profile is about 10 thick, and the fluorocarbon paint aluminum panel is 0.5mm thick, with 15Mpa stiffness or more. It has excellent performance, such as energy absorption, noise isolation, heat insulation and so on, and the thermal expansion coefficient is some inside and outside, to ensure smooth, non-burning.

4. The marble and the foam aluminum curtain wall panels

The composition between 3mm thick marble and 15mm thick foam aluminum, compared to the solid marble plate, can reduce 2/3 weight, but increase the impact toughness more than 2 times.

5. The sound insulation floor

With composite flooring from 5mm thick wood plate and 10 - 15mm thick foam aluminum, the floor spacing sound is able to reduce more than 20 dB.

6. Interior decoration entertainment

Ceiling and wall sound insulation decoration made of foam aluminum sound-absorbing panels used in karaoke, nightclubs and other entertainment places have a good noise reducing effect and excellent fire-resistant performance.

D. Needs in the traffic

1. Road sound barrier

The sound barrier made of the foam aluminum sound-absorbing panels at elevated road and viaduct can effectively reduce the low-frequency noise generated by the car. Foam aluminum sound-absorbing plate is 10mm thick, with the 60mm thick cavity set behind. And the general total height is 2800mm. The sound barrier noise reduction effect is two times the ordinary sound-emitting panel’s effect. 

2. Noise reduction in road tunnel

Noise reduction wall made of 10mm thick perforated foam aluminum sound-absorbing plate in the road and river bottom tunnel, the 60mm thick cavity set behind can effectively absorb the low frequency noise generated by the car. Foam aluminum profile does not absorb moisture, still maintain a good sound and noise reduction effect, and the foam aluminum side wall can absorb the impact of kinetic energy and vibration waves, playing a role in protecting the inner wall of the tunnel. The foam Aluminum profile does not corrode and burnt is safe to use.

3. Noise reduction submarine tunnel

Using the noise absorption noise wall on the river bottom made of 10mm thick perforated foam aluminum sound-absorbing, with 60mm thick cavity set behind, though the submarine tunnel humidity, the foam aluminum profile does not absorb moisture, still maintain a good sound and noise reduction effect, and foam aluminum side wall can absorb the impact of kinetic energy and vibration waves, play a role in protecting the inner wall of the tunnel. Foam aluminum sound absorption board surface, through nickel, spray treatment, can be resistant to seawater corrosion.
