There are two main types of sintered metal porous materials according to the source of raw materials: sintered metal powder porous materials and sintered metal fiber porous materials. Each material has its advantages and disadvantages. The former is easy to produce and has a wide range of applications. Any metal and alloy can be made into powder, and the cost is low;
The latter has high strength, can be folded and deformed arbitrarily, and has good permeability, but it is difficult to manufacture and high in cost, and the metals and alloys that can be made into fibers or wires are also limited. The following is a comparison of the application fields of the two:
Application fields of sintered metal powder porous materials:
Filter: Sintered metal powder porous material has good filtration performance and can be used to filter air, water and chemical substances, etc.
Catalysts: Sintered metal powder porous materials can be used as catalyst substrates for catalyzing chemical reactions, such as catalytic converters in automobile exhaust purification.
Adsorbent: The porous structure of sintered metal powder porous materials can be used to adsorb certain components in gases and liquids, such as for gas separation, water treatment and waste gas treatment.
Carrier materials: Sintered metal powder porous materials can be used as carrier materials for storing and releasing gases such as hydrogen, and can also be used for preparing electrode materials, etc.
Application fields of sintered metal fiber porous materials:
Heat insulation material: Sintered metal fiber porous material has good heat insulation performance and can be used for heat insulation and heat preservation of high-temperature equipment.
Filter: The fiber structure of sintered metal fiber porous material can be used to filter certain components in air and liquid, such as for air purification and oil-water separation, etc.
Catalysts: Sintered metal fiber porous materials can be used in catalytic reactions, such as catalysts in chemical reactions.
Biomedical materials: Sintered metal fiber porous materials can be used to prepare biomedical materials, such as artificial bones and repair tissues.
