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 no highway corrugated guardrail, traffic accidents will increase dramatically, but we drove on the highway, we often see different degree damaged guardrail guardrail, some have deformation, some column tilt. In this case, the guard board has played a very good protection effect, saving the vehicle and driver's life; if there is no guard plate, the vehicle will directly roll to the slope, the driver survived probability greatly reduced.
- Q: Is the grade B wave beam guardrail only installed at the corner?
- Loss of round column. Some sections of the soil soft, no compaction, into the round column is easy to lose. What's more, a bid section loses more than 1000 round columns. Even if these round columns are not missing. Can you meet the requirements of collision avoidance? The problem of lost column is actually the quality of construction.
- Q: What are the functions of urban road guardrail?
- 3, warning function: alert the driver, pay attention to the presence of guardrail and pedestrians, reduce traffic accidents.4, beautiful features: different materials, different shapes, colors available, consistent with the road environment. More traffic prevention problems can be Baidu "safe standardization", you can find a lot of security resources and knowledge.
- 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: Construction plan of plastic steel guardrail
- Three. Construction plan layout, temporary facilities layoutThe construction plan and temporary facilities layout of the project are detailed in the preliminary design form of the construction organization, E-4, general layout of the works.Four. Construction scheme and construction method of main project(1) earnestly preparing all construction preparations before construction;1, carry out quality and safety education, organize technical training, arrange post training, improve the quality and safety awareness of all construction personnel and business technical quality.2, organize relevant personnel to conduct on-site inspection, to seriously study the construction drawings, technical specifications and quality standards for detailed construction organization design and construction scheme; organize all the construction personnel familiar with the design documents, technical clarification on the quality objectives, and the fine decomposition to each process and each link from the construction quality; and the plan, implementation of each team, each head.3, reasonable arrangements for mechanical equipment parked on site, equipment maintenance, to ensure the normal operation can be started; the materials on site strictly inspection or test, to ensure that all materials delivered to the site in accordance with the specifications and design requirements, 100% qualified.4, C20 concrete mix ratio test, submitted to the resident supervision engineer concrete mix ratio test report.5, the preparation of the commencement report, submit detailed construction organization design, schedule, to be approved by the supervision engineer after construction, and then enter the overall construction stage.
- Q: What are the penalties for damaging highway and traffic safety facilities?
- Road traffic safety facilities include signal lights, traffic signs, road marking, guardrail, isolation grid, lighting equipment, line of sight guidance, anti glare facilities, etc.. Traffic safety facilities play an important role in ensuring traffic safety and reducing the potential accidents. For traffic safety facilities, the law has also given certain protection.
- Q: On the original double yellow line installed guardrail, logo is a double yellow line at the junction of the left, in the corner? Please state the laws and regulations
- The yellow line on the highway should not be riding or pressing, and there should be no turning and turning around the Yellow line.
- Q: What's the point 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: What is the price of the insulated barrier in the middle of the road?
- The utility model relates to an anti dazzling isolating guardrail for steel plate net, which is a novel isolation guardrail, and the white steel plate net is inlaid in the middle of the border to look more neat and novel.Road central isolation barrier price: generally according to height difference 60-120 yuan per meter.Road guardrail generally belong to traffic control department management, ordinary people generally do not ask this question
- Q: I want to buy an electric car.. Is it necessary to install a guardrail? Does electric car guardrail play a big role?
- Electric cars need to be fitted with guardrails. Should be called the bumper, it is necessary, ah, now the car shell is plastic parts, without touching, there are bumpers can be protected. Bumpers are important to protect cars from damage.
