Application of foam aluminum
the aluminum foam product has many special properties, can be widely used in aerospace, aviation, high-speed trains, city rail train, ship manufacturing, high-speed rail, construction, tunnel and along the sound barrier and other fields, has the advantages of light weight, high absorption, high damping, high impact energy absorption, high electromagnetic shielding performance, excellent insulation high temperature, combustion characteristics of refractory. Have unique environmental friendliness.
Characteristics of Foamed aluminum
Foam aluminum sheet is a kind of functional material with pore structure to obtain special properties, and has structural sensitivity. Its pore structure is different, the performance is not the same. Because of its unique hole structure, it has the following performance characteristics:
1. Light quality, small proportion. Aluminum foam density is only 0.15--0.50g/cm³ accounted for the same volume of fand, metal 1/50--3/52.
2.Excellent sound absorption performance. Good sound absorption properties of aluminum foams with capacity of up to 0.40--0.50., the average absorption coefficient for the aluminum foam fand 0.27g/cm³.
3. Foam aluminum, fire resistance, good temperature resistance. Generation of alumina in the foaming process of aluminum foam structure, excellent fire resistance, up to 800 ºC began to soften, the real melting to 1000---1200 ºC, and aluminum foam encountered fire play no toxic or harmful gas. The working temperature of foamed asbestos is usually 50--500 ºC, and the working temperature of glass panel is not more than 538 ºC.
4. Moistureproof and wet resistant. Commonly used glass wool, foam asbestos and other sound-absorbing materials, often because of water absorption or moisture absorption and greatly reduce the sound absorption performance. The moisture absorption rate of foam aluminum is almost 0, and the damp environment has little influence on its sound absorption performance.
5. High mechanical strength. Foam aluminum is a foam made up of metal skeleton and bubble. It is rigid structure and has good processability. It can make all kinds of sound-absorbing board.
6. Good insulation. The general thermal conductivity of metals is 10-300W/ (m.k), the thermal conductivity of the jade 0.2W/ (m.K), aluminum foam (diameter 2.7mm, the porosity is 73%---83%) apparent thermal conductivity is 1.9--2.2W/ (m.K), can be used as heat insulation materials.
