Porous metal foam is a metal material with a certain number of porous structures with a certain pore size and a certain porosity. It is a new material developed rapidly in the material science. The production principle is to electrolyze the required foam metal on a special polymer material skeleton having a three-dimensional network structure, such as polyurethane, polyester urethane and other special polymer materials (commonly known as sponge). The internal polymer material and the reduced metal oxide are burned out, processed by a chemical heat treatment machine, and finally a foamed metal product is obtained, so the foam metal has a three-dimensional multi-layer three-dimensional structure, high permeability, adjustable pore diameter, and both The dual function of functional materials and structural materials. It has various functions such as damping, shock absorption, noise reduction, heat insulation, flame retardant, filtration, gas distribution, electromagnetic shielding, etc., and has certain mechanical strength, and is light in weight and heat resistant. Corrosion resistance, large specific surface area, high chemical and electrochemical activity, no aging, etc., can work normally under high temperature and harsh environment conditions. Helps solve many application challenges.
