2. main features:
1) foam copper has good thermal conductivity and can be widely used for thermal heat dissipation of motors/electrical appliances and digital components.
2) the foam copper has excellent electrical conductivity, and its application on the electrode materials of nickel-zinc batteries and dual-electric layer capacitors is also valued by the industry.
3) due to the structural characteristics of foam copper and the basic harmless characteristics of human body, foam copper is also a good medical filtration material and water purification filtration material.
3. application areas:
(1) electrode material. good electrical conductivity makes foam copper can be widely used in electrode skeleton materials of nickel zinc batteries, dual electric layer capacitors and other new batteries. currently, foam copper has obtained multiple nickel-zinc batteries manufacturers for trial use and put into batches. at the same time, foam copper is expected to obtain promotional applications as a double-electric capacitor electrode fluid; in addition, foam copper is used as electrolytic recycled
(2) catalytic agent. in many organic chemical reactions, people try to directly use foam copper instead of punched copper plates with large surface area, as a chemical reaction catalyst; foam copper serves as a photocatalytic air purification carrier and has also obtained a relatively successful application.
(3) thermal conductive material. the foam copper has good thermal conductivity properties, making it a flame retardant material with excellent performance. it has been used in many advanced fire protection equipment abroad, especially as flame isolation equipment, which has excellent effects; in addition, people use foam copper good thermal conductivity and permeability to make heat dissipation materials for motors and electrical appliances.
(4) silencing and shielding materials. the sound waves have diffuse reflection on the surface of foam copper, and have achieved the silencing effect through the principle of expansion silencing, microporous silencing and other principles; the shielding performance of copper is close to that of silver, and it is an electromagnetic shielding material with excellent performance.
(5) filter materials. good structural characteristics and foam metal copper products that are basically harmless to the human body. as a medical filter material, it has also obtained a successful application; at the same time, foam copper also has a good future for applications in water purification devices.
(6) fluid pressure buffer material. the foam copper disperses and buffering effects on the fluid, giving it an excellent effect as a decompression protection device for various pressure meters.
