<p>A sintered hollow polyurethane spongy metal structure has porous skeleton construction with dodecahedron of reduced metal. The skeleton construction has hollow rigid configuration which appears geometric and comprises closed pores, semi-closed pores, semi-open pores. The interior and exterior of the construction has high tridimensional specific surface. The preparation method of the metal structure comprises following steps: forming a porous substrate, coating the substrate with metal, sintering the coated substrate to remove the combustible substrate, galvanizing the same metal to increase thickness, reducing the structure under hydrogen atmosphere .The metal structure can be used as carrier of air cleaning filter.</p> |
