Top curved acoustic panels

Aluminum foam is made after the additives in pure aluminum or aluminum alloy, after the foaming process together, with both metal and bubble characteristics, is a new type of porous sound-absorbing material. Aluminum foam acoustic panels and aluminum fiberboard directly exposed to the atmosphere does not need armor perforated plate and a filler, etc., easy to install. Aluminum foam sound barrier with stable absorption properties, the average absorption coefficient greater than 0.64, noise reduction coefficient around NRC0.75, mainly for low-frequency sound absorption performance outstanding traffic noise, higher than some of the other common sound-absorbing material, and in After rain and dust suction, absorption coefficient does not change, in line with the road noise barrier acoustic requirements. Aluminum foam acoustic panels can spray a variety of colors, while sound absorption performance is not affected, can greatly enrich the sound barrier landscape. Aluminum foam as acoustic panels and glass can be washed, and can achieve self-cleaning through natural rain will not affect the acoustic performance; once fouling, without affecting acoustic performance, but will increase the high-frequency sound absorption performance. Aluminum foam with a metal corresponding fire resistance, weather resistance, corrosion resistance, aging resistance, the design life of 20 years. Foamed aluminum acoustic board has excellent anti-glare properties. Aluminum foam sound barrier has been widely used in China, the Lupu Bridge, Xupu Bridge, A5 highway, Spring Road Viaduct have been applied, the aluminum foam, and has passed inspection. Shanghai Urban Outer Ring Road Pudong section is also being applied to install
