What is AluminumFoam?
Aluminum foam is a new concept metalmaterial which is foamed in sponge shape after melting aluminum ingot with various chemical ingredients and has many bubble layers inner structure.
Porous material is much lighterthan original one, which is the characteristic of porous. And, it improves the ability of energy absorption and reduces the abilityof thermal and electrical conductivities than original metal materials. Inaddition, porous material has wide applications as well as excellent ability ofsound absorption and permeability of liquid, air, etc.
Aluminumfoam, a metal itself, can be applied to aerospace aviation required the thermostability over 200℃. It is a 100% recyclabl ecofriendly material and absolutely will not produceharmful substances no matter in the process of producing, using or abandoning.
Main properties of aluminum foam
Density is 0.2~0.4g/cm3 (Aluminium1/10,Iron1/30, and Wood 1/4)
Soundabsorption
Porous structure has a good soundabsorption.
Aluminum foam sound-absorbing materialcan be used in the inner decoration of buildings (walls, ceiling and floor),railway, highway, factories, mechanical equipment and any other fields.
Suitable for noisy place.
100%non-flammability and no toxic gas released when burning.
Non-combustibility TEST verified to be qualified. <KIMM; IMO A.799 (19)>
I grade Non-flammability TEST ofaluminum foam surface verified to be qualified. <KICT; KS F2271>
Energyabsorption
Porous structure can effectively absorbenergy.
Have a great effect on energyabsorption after a high impact.
Firstly acquired the national SB5class (Guard rail shock-absorber)
Electromagnetic wave shielding ability
Aluminum foam has a function ofabsorbing electromagnetic wave
Widely used in military (stealth materials),TV station, hospital and any other electromagnetic shielding places.
100% recyclable Aluminum foam is nonpoisonous, odorless andharmless, no toxic gas released when burning.
Aluminum foam can be produced by recycled aluminum andits scraps.

- Q: Is the Viaduct installed sound barrier useful to middle - level households?
- but the specific degree of noise reduction to see the height of the sound barrier and the distance from the residents off the sound barrier!
- Q: Outside the park are installed sound barrier, and is necessary? Into the park but also around a way?
- If there are singing in the park to dance square dance and some of the big sound activities. Sound insulation Noise reduction Installation of sound barriers is very necessary.
- Q: Sound barrier and double glass which sound insulation is good
- if you are responsible for sound insulation construction, set up noise barriers on the road, and if you mean the road on both sides of the barrier is not a material difference,
- Q: Sound barrier production qualification where to do
- Rail Transit (Rail Transit) refers to the traffic volume, speed, safety, punctuality, protection of the environment, energy conservation and land use and other characteristics of the mode of transport, referred to as "rail", including subway, light rail, fast track, rail Trams and so on.
- Q: What kind of thing do you need to do?
- Sound barrier is used in the railway road side, absorbing the noise transmission, reducing the impact on nearby residents
- Q: Double sound barrier, sound insulation material, the average amount of sound is how much?
- Noise noise reduction Using sound barriers to reduce noise pollution is completely without problems. And the product can be used for more than ten years.
- Q: Who has the city road sound barrier CAD standard map ah
- We are a professional manufacturer of sound barrier, you can come to the factory to see the finished product, what to understand.
- Q: Is the thickness of the sound barrier set
- Certainly not ah, the inner layer is the sound absorption and load-shedding material, for this thickness, is obtained through scientific research results, not arbitrarily determined
- Q: High-speed railway sound barrier size which
- 4, the sound barrier to determine the length In order to avoid the end effect of sound barrier noise reduction effect, the design should be on the length of the sound barrier has a more reasonable selection. Now a large number of domestic sound barrier there are problems with the terminal effect. If the protection of 100 meters interval, the sound barrier to build 100 meters long, the terminal effect is serious, greatly reducing the sound barrier sound attenuation effect. From the effect point of view, the sound barrier built longer, the end effect will be smaller, the better the sound barrier effect. However, the sound barrier built too long will cause unnecessary waste. How does the length of the sound barrier be built to ensure the effect and save money? The author based on years of design research and practice experience, put forward "15 degrees angle determination method."
- Q: Sound insulation barrier and sound insulation wall which is good!
- Sound insulation barrier is better, convenient, do not occupy the place
