20ppi 30ppi 110ppi emf shielding sheet pure copper metal foam
Product Description
| Copper foam is a new type of multifunctional material with a large number of connected or disconnected pores evenly distributed in the copper matrix. Copper foam has good conductivity and ductility, and its preparation cost is lower than that of foam nickel. It has better conductivity. It can be used to prepare battery cathode (carrier) materials, catalyst carriers and electromagnetic shielding materials. In particular, foam copper has some obvious advantages when used as the base material of battery electrode, but its corrosion resistance is not as good as that of nickel, which limits its application. |

Application of the copper metal foam
(1) Electrode material. The excellent conductivity enables copper foam to be widely used as electrode framework materials for new types of batteries such as nickel zinc batteries and electric double layer capacitors. foam copper has been tried by many nickel zinc battery manufacturers and put into mass use. At the same time, foam copper is expected to be popularized and applied as electrode collector of electric double layer capacitors; In addition, foam copper has a very broad prospect as an electrode material for electrolytic recovery of copper containing wastewater.
(2) Catalysts. In many organic chemical reactions, people try to directly use foam copper with large specific surface area instead of perforated copper plate as a catalyst for chemical reaction; Foam copper has also been successfully used as the carrier of photocatalytic air purification.
(3) Thermal conductive materials. Foam copper has excellent thermal conductivity, which makes it become a flame retardant material with excellent performance. It has been applied in many advanced fire-fighting equipment abroad, especially as a flame isolation equipment with excellent effects; In addition, people use the excellent thermal conductivity and apparent permeability of foam copper to make heat dissipation materials for motors and electrical appliances.
(4) Silencing and shielding materials. The sound wave diffusely reflects on the surface of foam copper, and achieves the sound attenuation effect through the principles of expansion and micropore sound attenuation; Copper has shielding properties similar to silver, making it an excellent electromagnetic shielding material.
(5) Filter material. Foam metal copper products, which have excellent structural characteristics and are basically harmless to human body, have also been successfully used as medical filtration materials; At the same time, the application of foam copper in water purification equipment also has a good future.
(6) Fluid pressure buffer material. The dispersion and buffering effect of foam copper on fluid makes it an excellent pressure relief protection device for various pressure instruments.
