High temperature resistant foam
has many excellent properties due to its unique structure, and has been widely used in aerospace, aviation, transportation, construction, environmental protection, energy, biology and other high-tech fields, as well as the needs of general industrial applications. It is the significance of the development of this new type of material. High temperature resistant foam has a large specific surface area, through-hole metal foam can be used to make heat exchangers and radiators; closed-cell metal foam can be used as a thermal insulation material.
One of the important uses of foam metal is to use the characteristics of absorbing impact energy to manufacture buffers and shock absorbers. Its applications range from impact baffles for automobiles to spaceship landing gear, and has been successfully used in elevators, conveyor safety mats, and energy-absorbing linings for high-speed grinder guards. Using the sound-absorbing properties of high-temperature-resistant foam metal, it is mainly used for noise reduction and noise reduction, such as attenuation mufflers for steam power plants, pneumatic tools, and cars.
Taking advantage of the permeation properties of high temperature resistant foam, it can be used as an important material for the preparation of filters. Compared with powder metallurgy porous metal, it has the characteristics of large pore size and high porosity, and the filter made with it has a wide range of applications, such as filtering out solid particles in liquid and gas.
It can also be used in the construction industry, such as interior and exterior decorative parts of buildings, curtain walls, interior walls, etc.; it can also be used as a computer stand; various packaging boxes, etc. Utilize the fire resistance of high temperature resistant foam; it can be used for refractory materials in industries such as construction; or by treating its holes, it can be used for flame retardant materials, etc. In chemical industry, it can be used as a catalyst carrier. In addition, the high temperature resistant foam metal can also be used as a porous electrode. Cellular foam has a high shielding coefficient for high-frequency electromagnetic waves, and has been used to make electronic instrument housings and build electromagnetic shielding rooms.
