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:Which sound barrier noise reduction effect is good
- and if you mean the road on both sides of the barrier is not a material difference, whether it is Made of steel plate or made of glass is to let the sound of a way to be isolated, so that the sound up to go, are possible, you can consider the next budget and beautiful
- Q:Railway sound barrier installation costs how much money a square meter
- the price difference is very large, ranging from 200-500, the same specifications, color steel plate material price is the cheapest.
- Q:Do you know what the sound barrier is?
- Sound barrier, mainly for highways, highways, elevated road and other noise sources noise reduction noise. Is divided into pure sound of the reflective sound barrier, and sound absorption and sound insulation combined complex sound barrier, which is more effective sound insulation method
- Q:What is the price of the sound barrier? What is the price of the sound-absorbing barrier for high-speed rail and expressway and railway station?
- Metal consumption of the reserves, the general use of ceramic, with the mud burned :) Stiffness with the shape and beauty have to achieve, and not brittle, not fragile, easy to install, easy to transport. You can choose the sound of Dr. high temperature honeycomb ceramic sound absorption board :) If necessary, find my ID
- Q:The sound barrier of the beam beam template installation need to pay attention to what matters
- (1) scaffolding at the bottom of the pole with different lengths of steel pipe arrangement, the two adjacent column joints in the height of the direction of the distance should not be less than 500mm; the center of the joints from the main center of the main The distance of the node should not be greater than 1/3 of the step. The length of the lap should not be less than 1m, not less than two rotary fasteners, the edge of the end of the cover to the rod end of the distance should not be less than 100mm. (2) stand on the ground pole should be set mats, and set the vertical and horizontal direction of the sweeping pole, connected to the foothold on the bar, from the bottom is very happy to answer the landlord of the problem if any mistakes please forgive me
- Q:Is the railway sound barrier and the protective screen a thing?
- Sound barrier and sound insulation wall is a kind of thing that is environmental noiseproof noise reduction And the protective screen is anti-X-ray radiation and the like is not a thing
- Q:Highway noise board, noise barrier barrier wall sound barrier how much money a square
- Full set of words to buy (including columns, accessories, sound-absorbing panels) per square meter between 150-280 yuan, the size of the different sizes are also different.
- Q:What are the technical parameters of the sound barrier?
- Overview With the rapid development of China's traffic network, sound barrier as a solution to the current traffic noise problem, has been more and more applications. However, from the current domestic built sound barrier effect, some are not very good, to the country and the people caused unnecessary waste. The main reason for this is that most of the sound barrier design is not scientific basis, blindness is relatively large. Where to set the sound barrier, and how to determine the length of the sound barrier (L), sound barrier height (H) and other parameters are determined by the feeling. Based on years of experience in sound barrier research and design practice, the author attempts to give the practical method and empirical formula of the above parameters in the design of sound barrier, which is designed and used by designers in the future sound barrier design.
- Q:How long is the high-iron away from the community to install the sound barrier 21 layer to hear the noise?
- This is also the main sound barrier sound effects how to look like, because there are many kinds of sound barrier quality, noise effects are different.
- Q:Isolation noise Why choose sound barriers
- 10), high strength: combined with different regions of China's climate conditions, in the structural design to fully consider the wind load. Using 1.2 mm galvanized sheet, through the automatic production line, to suppress the groove to increase the intensity of the product against the 10-12 level typhoon, compression 300 kg / ㎡. 11), waterproof, dust: louver design fully consider the waterproof, dust, the angle set to 45 °, dust or rain in the environment, its sound absorption is not affected, the structure has been set up dust drainage measures, Avoid water inside the component. 12), durable: product design has fully taken into account the road of the wind, the impact of traffic vehicles and the impact of the atmosphere of the open-air anti-corrosion. Products using aluminum alloy coil, galvanized Coil, glass wool, H steel column galvanized surface treatment. The company guarantees that the product does not corrode within 30 years, the same type, sound absorption, sound insulation effect is not reduced.
