The new material of foamed aluminum refers to the foaming process after adding additives to pure aluminum or aluminum alloy. It has the characteristics of metal and bubbles at the same time. The new aluminum foam material has high heat resistance. Generally, the dissolution temperature of aluminum alloy is about 560.700 °C.
(1) Noise reduction and shielding materials. The sound wave is diffusely reflected on the surface of the foamed aluminum, and the effect of noise reduction is achieved through the principles of expansion noise reduction and microporous noise reduction. The shielding performance of aluminum is close to that of silver, and it is an electromagnetic shielding material with excellent performance.
(2) Catalyst. In many organic chemical reactions, people try to directly use new aluminum foam materials with large specific surface area to replace punched aluminum plates as catalysts for chemical reactions; aluminum foams have also been successfully used as photocatalytic air purification carriers. Material.
(3) Fluid pressure buffer material. The dispersing and buffering effect of foamed aluminum on the fluid makes it a decompression protection device for various pressure instruments, which has excellent effects.
(4) Thermally conductive material. The new material of aluminum foam has excellent thermal conductivity, making it a flame retardant material with excellent performance, which has been applied in many advanced fire fighting equipment abroad, especially as flame isolation equipment. Thermal conductivity and apparent permeability, it can be made into heat dissipation materials for motors and electrical appliances, and new foam aluminum materials.
(5) Electrode material. The excellent electrical conductivity makes the new aluminum foam material widely used in the electrode skeleton material of new batteries such as nickel-zinc batteries and electric double layer capacitors. At present, aluminum foam has been tried by many nickel-zinc battery manufacturers and put into mass use. , Foamed aluminum is expected to be popularized and applied as an electrode current collector for electric double layer capacitors; in addition, foamed aluminum is used as an electrode material for electrolytic recovery of aluminum-containing wastewater, which also has a very broad prospect.
(6) Filter material. Excellent structural properties and basically harmless to human body, aluminum foam products have also been successfully applied as medical filter materials; meanwhile, aluminum foams also have good prospects for application in water purification devices.
