nickel foamIt is a new type of porous material, usually made of high-density metals such as nickel or copper. Because of its high specific surface area and pore volume, foam nickel has excellent sound absorption, heat insulation, cushioning and impact resistance.
Characteristics of foam nickel
High specific surface area: foam nickel is a porous material, so its specific surface area is very high, about dozens or even hundreds of times of ordinary metal.
Corrosion resistance: foam nickel has good corrosion resistance and can be stable in a variety of chemical media.
Sound absorption performance: foam nickel has a high sound absorption value, especially in high-frequency areas, and its sound absorption performance is particularly excellent.
Thermal insulation performance: foam nickel has excellent thermal insulation performance, which can keep cool under high temperature.
Cushioning performance: foam nickel has high cushioning performance, which can effectively buffer the collision between materials and objects.
application area
Foam nickel is mainly used in construction, transportation, machinery manufacturing and other fields. In the construction industry, foam nickel can be used to prepare wall insulation materials, sound absorption materials
Thermal insulation materialWait.
In the field of transportation, foam nickel can be used to prepare sound insulation and heat insulation materials. In the machinery manufacturing industry, foam nickel can be used to prepare structural materials, sealing materials, etc.
Production method of foam nickel
Metal such as nickel or copper can be made into foam nickel by thermal oxidation or electrolytic deposition. The foam nickel prepared by this method has high specific surface area and pore volume, so it has good sound absorption and heat insulation properties. In addition, the pore structure of foam nickel prepared by thermal oxidation or electrolytic deposition is stable, so it has high impact and wear resistance.
Production equipment and process of foam nickel
Foam nickel is usually produced by molten salt electrodeposition. This method can deposit metals such as aluminum or copper onto a ceramic substrate through high-temperature molten salt droplets to form a porous structure. In addition, electro deposition can be used to composite with other materials to manufacture structures and functions with different properties
Foam nickel material.
summarize
Foam nickel is a new porous material with excellent performance and wide application, which has high specific surface area, corrosion resistance, buffering, sound absorption and impact resistance. Because of its unique structure and performance, foam nickel is widely used in construction, transportation, machinery manufacturing and other fields.
