Application of metal foam in explosion-proof flame retardant

Metal foam is a porous metal with a porosity of more than 90% and a certain strength and hardness. This product is a metal material containing pore foam, the porosity is higher than that of ordinary sintered porous metal, and the pore size can reach 7 mm.

Metal foam is a two-phase composite material composed of pore dispersed phase and metal matrix skeleton continuous phase and phase, and its properties depend on the influence of metal matrix, porosity, pore structure and preparation process.

Metal foam has good fluid permeability and good fire resistance. It can be placed in pipelines carrying flammable gases or liquids to stop the flame from spreading by absorbing heat, thereby stopping the explosion.

Metal foam is suitable for acetylene, oxygen flame gas welding and gas cutting technology, mining motors and power switches, oil refining and combustible gas pipelines, burner systems, oil and gas recovery systems, heating furnaces, gas purification systems, etc. It can also be used as a fire-proof and explosion-proof filler for storage tanks such as liquefied gas and fuel.
