Product Description:

Aluminum foam is a new concept metalmaterial which is foamed in sponge shape after melting aluminum ingot withvarious 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% recyclableeco-friendly material and absolutely will not produceharmful substances no matter in the process of producing, using or abandoning.

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)>

Ⅰgrade 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.

Aluminumfoam can be produced by recycled aluminum and its scraps.

Q:What is the best sound insulation decoration
Economical and practical choice is 2/4 red brick walls, both sides of the cement wall. This partition wall must be piled to the top, you need to take the ventilation pipe or other traces and then through the hole, should pay attention to the pipeline sealing problem, otherwise the same can cause crosstalk phenomenon. Followed by noise wall panels, this material is a professional sound insulation material, both sides of the metal plate is the middle of the sound insulation foam plastic, the greater the thickness of the wall board the better the noise effect.
Q:What are the materials on the roof of the building?
Top and floor sound insulation. Most of the floor will not come much noise, most of them by the stampede on the floor issued by the sound, so you can use the carpet or silhouette floor, etc .; important is the sound from the ceiling, where the sound is upstairs, roof decoration Mostly for the ceiling or solid wall structure, you can also add a layer of sound insulation material, according to the decoration of the master's proposal or through the physical structure silence.
Q:What is the general rule of soundproofing material?
For the double layer of gypsum board wall, the law of quality plays an important role, that is, to increase the number of layers or thickness of the board can be improved sound insulation. As the keel double wall system sound vibration form is very complex, so the embodiment of the law of quality than the simple single-wall complex.
Q:What is the principle of noise board?
A kind of transmission of sound is called intermediation. That is, from one medium through the critical contact surface of the two media into another medium, at this time, the transmission of acoustic energy is the transmission of vibration amplitude. Cross-media propagation, the greater the difference between the density of the two media, the greater the loss of sound energy. In practice, the air is the human normal space, so the greater the density of the material with the density of the material is generally a very high density material (much lower than the air density of the material in addition to vacuum, really not much), that is, Can be regarded as sound insulation material. The higher the density, the better the sound insulation. Such materials made of sheet metal, known as sound insulation board. Sound insulation method is to use a soundproof material to isolate the sound source from the surrounding environment, so that the radiation noise can not be directly transmitted to the surrounding area, so as to achieve the purpose of noise control. The essence of sound insulation is to minimize the sound from the sound source radiation, commonly used measures are sound insulation and sound insulation structure.
Q:What is the type of noise board?
According to the classification of civil engineering categories, can be divided into building noise and structural noise two.
Q:How easy it is for the soundproof wall to be soundproof
The thickness of the noise wall is determined by the size of the noise source. The larger the noise source is, the more the thickness of the noise wall will be increased. Generally, the thickness of the noise wall will be sacrificed at about 5-10 cm.
Q:What is the best soundproofing of the piano room?
The general street-like noise with a soft bag to isolate some to ensure that all to try the curtains to the goose down cloth kind of thick things to move away to take the curtains side of the joints to use things to try to make it close
Q:What is the noise insulation material of the car?
Car noise products are divided into four categories: A, shock absorber material B, sound-absorbing material C, sound insulation material D, sealing material, from the lightweight development trend, the ideal car sound insulation material is not shock absorption, sound insulation, sound-absorbing products Of the paste, but should be a product of these kinds of sound insulation principle of the integrated use.
Q:What are the cheapest sound insulation materials?
Sound insulation materials are mainly soundproofing function sound insulation material green no harm fully meet the environmental protection E1 level fire safety requirements of the fire rating of A level of its cheap price of cheap material is mainly used for bar, KTV, karaoke OK, night and so on need to sound insulation
Q:How to buy sound insulation sound insulation of the best sound insulation
As the sound back and forth in the cavity several times with the glass wool friction and heat consumption. Need to use 3-5cm, 24kg-48kg of centrifugal glass wool as a fire-filled material- filled material, you can increase the volume of 5-8db.
