Installation method ofsound barriers on highway and railway.

1. Mark the keel beaminstallation position on the high speed railway (expressway)

2. Install and fix the keelbeam

3. The distance between two beams is 500-600m

4. Install Aluminum foamsound-absorbing panel

5. Inset Aluminum alloy frame in order to fix the Aluminumfoam panel

6. Fix it to the beam with bolts

7. In order to prevent the bolts from loosening,install sturdy nuts.

*Precautions

1. Materials used for the high speedrailway (expressway) must be stainless steel or aluminum.

2. The specification of Aluminum foam sound-absorbing panelis adjustable as the design of high speed railway (expressway)

3. Color of Aluminum foam sound-absorbing panel can becustomized as required.




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


Ultra-light

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.

Non-flammability

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.

Eco-friendly

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: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: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 is the sound barrier? What is the specific effect?
A sound barrier is a facility that blocks sound waves between the sound source and the receiver, thereby reducing the noise in the area where the receiver is located. According to the sound barrier application environment, the sound barrier can be divided into traffic noise barriers, equipment noise attenuation noise barriers, industrial plant noise barriers three.
Q:What is the current domestic production sound barrier is more famous?
Currently known as Jiangmen Tianchang Acoustic Hardware Electric Co., Ltd., the public development center began in 1996,
Q:Sound barrier base steel pipe pile how to do
According to the drawings design requirements can do
Q:Sound insulation barrier and sound insulation wall which is good!
Sound insulation wall covers an area, large volume, opaque, maintenance and maintenance trouble. High-speed edge is prone to air turbulence. As well as to the past car a sense of oppression.
Q:How much is the sound barrier?
There are some high-speed use of metal sound barrier medium price, the high requirements of the light, you have to set pc patience board, relatively expensive, 340 or so a flat
Q:Xuzhou has no sound barrier to the production of environmental protection company?
