100% Recycling Soundproofing Closed Cell Aluminum Foam Panel
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: What are the significance of installing high speed guardrail?
- If there is no guardrail on the expressway, the traffic accident will be more serious. A lot of friends to travel during the holidays, the highway multi car pileup accident occurred a lot, the car was a guardrail or if there is no bus stop supporting It is often seen., knocked out the plate damage is more serious, the mortality rate will be greatly enhanced.
- Q: How much is one meter for the road barrier?
- 2, zinc steel guardrail rail is the bread and oval galvanized steel pipe, the middle vertical rod is a plum tube, in the middle of a semi-circular reflective film
- Q: What is a highway guardrail drilling machine? What's the difference between it and highway guardrail and pile driver?
- However, as far as I am concerned, the highway guardrail drilling machine is a more advanced engineering equipment, so it is not very common in the market, and only a few other enterprises can produce it. Because the highway guardrail drilling machine is a machine called "macro road machinery" enterprises to develop their own production and application, patent protection has been made, so the relevant knowledge on the market is relatively small.
- Q: Sidewalks, overpasses, tunnels, fences, these are traffic facilities or road facilities?
- It must be traffic facilities. The bridges and tunnels are structures. They belong to the road, and the sidewalk structure itself is the road
- Q: Does the traffic barrier isolation work belong to the construction project?
- Thermal power engineering, hydropower engineering, nuclear industry engineering, materials engineering, metallurgical engineering, nonferrous metals engineering, petrochemical engineering, chemical engineering, pharmaceutical engineering, mechanical engineering, aerospace engineering, marine engineering, light industry and weapons engineering, textile engineering, electronics and communication engineering and radio film and Television Engineering
- Q: Determination of traffic accident responsibility for pedestrians crossing guardrail
- You pedestrian streets around, do not obey the traffic rules, my car is a one hundred pair of eyes can not see here. All is not lost to the people. Brother, don't be afraid, go to the traffic police team to go to the car, there is reasonable place!
- Q: What is the height dimension of highway guardrail?
- This range of values takes into account the adult height to prevent crossing as the primary design goalI hope I can help you
- Q: How much is it per meter per meter for guardrail of highway bridge?
- According to the technical specification for construction of highway traffic safety facilities, JTG F71-2006 No.
- Q: Crash guardrail 3-5 meters, afraid to ask me more money, I did not report insurance, I think the loss is not much, I did not expect to repair the car to 4400 yuan. Hey, now have to repair at their own expense, depressed.
- When driving into the middle of the road, the guardrail should pay for the guardrail, and then pay the fine given by the traffic police.One of the ninety-ninth acts that refer to the traffic law shall be fined by the Department of traffic control of the public security organ for not less than two hundred yuan but not less than two thousand yuan:
- Q: Do you need an intermediate guardrail for a eighteen meter wide road?
- In order to make the night traffic flow and traffic safety, should be gradually set up along the reflective signs and reflective safety facilities, lighting to transport characteristics in busy and important sections, in the condition of the crossing the crosswalk, etc. can use local lighting.At the risk of construction work, rockfall, collapse sections, set the road guardrail; the obstacle in the road section, set the traffic cone direction; change occurred in a section where set oriented standard. Guide marking, guiding and guiding.Set up traffic barrier safety facilities, in order to ensure the safety of traffic and pedestrians, and give full play to the role of the highway. But the traffic barrier is not omnipotent, or people need to obey the road safety regulations consciously.
