Product Description

 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

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:Should a guardrail be installed on a high embankment with a radius less than the radius?
In the highway and a highway, in order to avoid collision and pedestrian and vehicle, the vehicle shall be installed to prevent intrusion to traffic barrier and prevent pedestrians crossing the Lane Lane protection network in accordance with the regulations, all levels of highway embankment, bridge approach, minimum limit radius, steep slope area should be set up barriers or warning pile.In order to induce the driver's line of sight and ensure the safety of driving, a sign is used on the required section to indicate the edge and alignment of the highway. In poor visibility, sharp bends and intersections could be combined with other safety assurance measures, set up signs, mirror or lane etc..
Q:If you crash the guardrail, do you want to pay for it?
(two) the vehicle is handed over without obtaining a driving license or driving license is revoked or withheld driver; (three) after causing a traffic accident, does not constitute a crime; (four) the vehicle exceeds the speed of fifty percent; (five) forcing motorists to violate the road traffic safety laws the regulations and requirements of safe driving motor driving motor vehicle, causing a traffic accident, does not constitute a crime;
Q:There is no legal basis for road fines when traffic accidents cause damage to highways
According to the appraisal conclusion, the compensation for road loss is compensated. At the same time identify the conclusions, the future insurance company claims are also very effective proof. Specifically, I would like to ask people who know the law
Q:Can a barrier block be used in the central divider and combination guardrail?
content validityThis atlas is applicable to the construction design of traffic safety and protection facilities for new roads, expansion and reconstruction projects of urban roads in our country. Including guardrail, glare panels, guardrail, median openings, guardrail fence, fence separated overpass Road Central City
Q:What's the point of installing high-speed guardrail?
If the highway does not have a guardrail, it may cause a great impact, so that the driver can not miss the correct judgment because of the width of the road, leading to a large traffic accident and affecting the safety of life.
Q:Who has done the road guardrail advertisement?
You are obviously against the first and second! If you have to do it, there will be many departments involved, such as the Transportation Bureau, the Bureau of industry and commerce, etc.! So no risk taking is recommended! You go to dredge the city management, they will push this to industry and commerce, even if dredge the city management, business and that side you can not get through! In China, no such precedent, no one dared to open!
Q:Whether or not the guardrail end of the highway needs to be put into anti-collision barrels
A crash bucket is installed at the end of the end to play a role in improving the warning effect. This is permitted by law, but not by specification!
Q:White M - shaped guardrail on the street. Why is it called Beijing guardrail?
Two, anti-corrosion treatment:Hot galvanizing, cold galvanizing, dipping, spraying etc.Three, product function:1 separate functions: traffic guardrail will motor vehicle and non motor vehicle and pedestrian traffic space, road were separated in the longitudinal section, the motor vehicle and non motor vehicle and pedestrian lane, improve traffic safety, improve traffic order.
Q:What are the types of traffic barrier and the size and requirements of each classification?
Some city and often because of economic conditions, the cement fence, guardrail tube, but due to the lack of detailed design, appearance is very poor, the role of guardrail is poor, but also affect the city environment; some city one-sided emphasis on decoration, while ignoring the inherent barrier functions: such as some "safe" city of stainless steel guardrail, but did not pay attention to the optical design of guardrail, stainless steel guardrail brought to light pollution caused by glare, impact safety; some non-standard guardrail design, guardrail is too high, the influence of city landscape
Q:Reaction traffic barrier problem can not be solved, how to do?
Traffic barrier is generally maintained by the local traffic management bureau, you can find the local traffic control bureau to reflect the situation, the traffic control institute, if you want to deal with traffic barrier problems
