Sphere open cell aluminum foam
The bubble cabin is spherical and relatively regular. Small round holes are opened on the bulkhead to connect the spheres and open to 6 directions to avoid straight holes, which is conducive to sound absorption, filtering and sound attenuation. In practical application, the ideal application effect can be obtained through the design and process control of the size of the sphere (diameter 4-13mm), the size of the wall hole (diameter 0.5-4mm), the thickness of the hole wall and the thickness of the plate. Bulk density: 0.5-0.8g/cm3. Approved by the National Building Materials Testing Center of the Ministry of Construction, the noise reduction coefficient of TJ's foam aluminum exceeds the international standard. The spherical aluminum foam products produced by our company are materials that combine the advantages of open-cell and closed-cell materials, and overcome the shortcomings of open-cell and closed-cell materials themselves. At present, only our company TaiJie and Bremen Company can produce spherical aluminum foam in the world.
Spherical aluminum foam is an excellent product of aluminum foam sound-absorbing materials at home and abroad. It is suitable for noise reduction and noise reduction of various vehicle boxes and mechanical equipment; due to the uniform distribution of spheres, the same pore shape, and regular pore walls, it is also longer than absorbing energy. It has excellent impact resistance. Compared with the irregular cell shape of closed-cell aluminum foam, the spherical open-cell cell wall is less likely to break during collision and stress, and it is used as an impact-resistant buffer material with better performance.
