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: The price of sound barrier which is more appropriate, of course, the quality to be reliable Supplement, the column of the specifications of what kind of usual, the price how
- airport fence, prison fence, temporary fence and so on the sound barrier and fence manufacturers.
- Q: Sound barrier steel mold where to do good? To suggest!
- This kind of cover plate steel mold is mainly made of iron plate welding, has a very convenient, fully protect the normal use of the shutter prefabricated. This kind of shade steel mold is also often used one, better satisfied with the use of high-speed high-speed rail
- Q: Silent barrier of high-speed railway is generally how much load
- This not only to the country caused by the heart of the loss, but also played a role in the destruction of the city landscape.
- Q: What is the sound barrier on the edge of the railway?
- FRP sound barrier cost is high, no fire. The new magnesia sound barrier is modified with magnesium chloride cement as the base material, is an inorganic non-combustible material, has good corrosion resistance and acoustic properties.
- 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. Second, the basis for preparation 1, "Nanchang to Yichang Expressway Shixiong to Songxian two-stage construction design"; 2, "highway bridge and culvert construction technical specifications" JTG / T F50-2011; 3, "highway engineering quality inspection and evaluation standards"; JTGF80 / 1-2004 4, site survey survey obtained engineering geology, hydrogeology, local resources, traffic conditions and construction environment and other information.
- Q: Combination sound barrier steel mold sound insulation effect
- Sound insulation, height and length are two key, double sign highway combination of sound insulation as long as the road and the receiver can block the line of sight, at least you can reduce the volume of 5 dB, and each additional 1 meter, can reduce 1.5 dB
- Q: Highway sound barrier manufacturers sound barrier price is how much
- Different sound barriers of different shapes Sound absorption material different prices are different.
- Q: Where are the sound barrier molds used? What is the difference between a mask and a mask?
- Generally used in high-speed junctions and residential areas between the barrier, and some places used in stations, high-speed rail stations and other places. Now this is already very popular, ah, we Hebei permanent mold factory dedicated to do this mask mold and sound screen mold, are very professional. Sound barrier mold commonly used length of 3960mm with 1960mm
- Q: Sound barrier construction, supervision should pay attention to what aspects of quality control
- (Including single tube rubber), EPDM rubber pad (between the unit board seal) Buffer effect) and gravity mortar.
- Q: Roof fan noise barrier where to sell
- Restaurants, cold stores, hotels or some entertainment will inevitably install the fans in the roof, such as exhaust fans, blowers, ventilation fans, induced draft fan, etc., they play the role of air flow, keep the indoor fresh air Or the combustion has an important role, but the installation of the fan is often accompanied by a strong noise, for the surrounding residents is unacceptable, it should be the rest of the time, the fan is still whirring operation, complaints of businessmen Countless. Fan off the big need, as long as the fan around the installation of the roof fan noise barrier, noise protection measures can be done.
