Metal closed-cell aluminum foam panels for sound insulation
It is made of pure aluminum, and widely applied in the field of military, preparing and application development of new material, noise control, firproof, electromangnetic shielding, decoration energineering, modular integrated housing, etc.
Aluminum foam' advantages
• Noise absorption: coefficient is above 0.75
• Fireproof and waterproof: it better than glass cotton and wool rock
• Electromagnetic shielding: can reduced by 65~90dB
• Energy absorption
• Nonflammable, heat dissipation and high temperature resistance
• Lightweight, east to install, etc.
Application Projects
The equipment noise came from oil pump, electric machine, valve body during gas transimission at the gas station. After site testing, the soundproof box noise level is 90dB. After closing the door, the noise level is 84dB. The effect of soundproof box' decreasing noise level is noly 6dB. This result can not meet the demand of city noise reduction standard. But after installing our soundproof box, it not only meet the noise level standard, but also has fire prevention function.
You can reference the following pictures, which are test result.
