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?
- Will be helpful, the sound is blocked by the sound barrier barrier from the top out, will greatly reduce the noise,
- Q:Sound barrier and double glass which sound insulation is good
- 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:Sound barrier construction supervision should pay attention to what aspects of quality control
- 1. With the vertical line, to determine the level of vertical and vertical column, with a gasket to hold the column. 2, fixed steel column, the anchor bolts on the more than a nut to ensure that the connection is stable.
- Q:Sound barrier base steel pipe pile how to do
- According to the drawings design requirements can do
- Q:The structure of the sound barrier
- Sound barrier height between 1m and 5m, covering the effective area of ??the average noise reduction of 10 ~ 15dB (A) (125Hz ~ 40000Hz, 1/3 octave), up to 20dB (A). In general, the higher the sound barrier, or the farther away from the sound barrier, the better the noise reduction effect.
- Q:Air conditioning outside the machine noise, air conditioning with external sound insulation barrier to treat good or air conditioning machine sound insulation cover good?
- To see the specific situation, the noise management is not so simple! Do bad words, money white flowers, no effect. You can find some professional companies
- Q:Does the height of the sound barrier affect the sound insulation?
- so that the sound up to go, are possible, you can consider the next budget and beautiful
- Q:How much is the sound barrier?
- Different areas of the highway sound barrier to choose the material, style, sheet thickness, the amount of engineering is different, the price difference is very large, ranging from 200-500, the same specifications, color steel plate material price is the cheapest.
- Q:Where are the sound barrier molds used? What is the difference between a mask and a mask?
- Sound barrier mold applications in high-speed, bridges, high-speed rail has played a good Runda anti-noise function. Runda shield is mainly used to cover the embedded parts, the full protection of high-speed rail high-speed rail smoothly. This kind of cover plate steel mold is mainly made of iron plate welding, has very good convenience, fully protects the shutter preform The normal use. This kind of shade steel mold is also a kind of often used, and better meet the high Speed high iron use
- Q:What are the acoustic barrier categories?
- 1 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.
