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: Sound barrier workers installation fee
- The installation of the sound barrier can not be said specifically in the road, roads, factories and other flat roadbed installed sound barrier, if you do not calculate the freight, billing, etc., manufacturers or companies to provide installation, then about 25-40 yuan / square meter; Bridges and other high operating installation, probably need 30-50 yuan / square meter.
- Q: What is the sound barrier
- Sound barrier is an environmentally sound noise reduction products
- Q: Sound barrier construction program
- Sound barrier construction program First, the project profile Hubei high-speed section of the starting mileage for the K42 +907.5 ~ K49 +328, 6.42km long. Line Jingzhou City, Hubei Province through the town of Mengxi town, Nanping town. I have a total of 1 sensitive points, located in the Golden Horse Village 10 lines on the left side of the line from the nearest 80m, in the sensitive point of the design of the sound barrier. The subgrade design sound barrier length of 300m, the left from the mileage of K46 +780 ~ K47 +080. Roadbed sound barrier height of 3.015m, the basic part of the φ140 steel pipe pile foundation, steel pipe length 2.8m, spacing 2.1m, buried depth of 2.5m. The upper pouring joint beam and column, using C20 reinforced concrete structure. Between the beam above the column and the use of sound-absorbing brick masonry, and every 30m set up a expansion joints, a total of 29 Road.

- Q: What is the sound barrier? What is the specific effect
- In the way of expression of their feelings deeply infected .This real emotional expression, so that writing transmission of a strong appeal, I also cried. I played for this essay excellent - in accordance with the general requirements of writing , Although it is not really good.I reason to give this essay excellent, because this essay has "some words" of quality.

- 3, sound barrier surface treatment and sound barrier filler Surface treatment: electrostatic spraying, painting, and some sound barrier manufacturers such as ring Sheng traffic equipment has its own spray line, so the price will not be too high, there is sound barrier filler, rock wool and centrifugal glass wool, and bulk density also There will be differences. 4, the selection of sound barrier shape
- Q: Railway sound barrier belongs to the high-speed rail industry which type
- High-iron sound barrier is based on the current high-speed railway needs to design a sound barrier.
- 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
- 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: Noise reduction measures by the sound barrier to sound insulation window is not weakened
- Although the sound barrier to control the impact of a certain noise, but the need for adequate height and length of the effectiveness of protection. If the height and length of the lack of that can only play a psychological comfort.
- 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.
