High Porosity Metal Nickel Fiber Felt

https://www.toptitech.com/microporous-filter-components/high-porosity-metal-nickel-fiber-felt.html

High-porosity metal nickel fiber felt is a patented product, which is a three-dimensional nickel felt made of metal nickel fiber developed in chemical and metallurgical processes. The purity of nickel fiber felt is 99.5%. It is a new material with light weight, good flexibility, adjustable porosity and felt thickness.

Metallic nickel felt is made of micron-sized pure nickel fiber in accordance with international technical standards, through a special felting process and ultra-high temperature vacuum sintering process. Compared with nickel mesh or nickel powder sintered plate, nickel fiber felt has a good three-dimensional network porous structure, high porosity, large specific surface area, uniform pore size distribution, strong corrosion resistance, good water permeability, good heat dissipation, and current density high, low voltage, stable performance, long life and other advantages.

Widely used in fuel cells, military industry, aerospace, civil, medical and other industries. Especially hydrogen fuel cell diffusion media: anode diffusion layer (GDL) for proton exchange membrane (PEM) water electrolysis.

Product Features

Good electrical conductivity

High mechanical strength

Good chemical stability

Strong corrosion resistance

Large specific surface area

The fibers in the sintered fiber mat are overlapped with each other, and each fiber is welded with several fibers. The overlapping points are in a slightly fused state, and the entire fiber mat forms a complete conductive network with excellent electrical properties. And it also has a large specific surface area, which is mainly determined by the characteristics of the preparation process of the nickel fiber felt. The drawn fiber itself has a large surface area, and the fiber is laid into a net to form a network structure that is evenly overlapped with each other.

Application fields

Filter material

Due of its good permeability, foam metals are widely employed in the filtration business, notably in industrial filtration, and may be formed into many kinds of filters. The idea is that solid particles contained in fluid can be stopped and trapped by the pores of foam metal materials, which also serve as filters and separators of gas and liquid. and then purifying or separating the medium. Foam metal filters can filter solid particles and other substances from liquid (such as petroleum, gasoline, refrigerant, polymer melt and suspension, etc.), or air and other airflow media.

Photocatalyst series air filter screen

The photocatalyst components in this line of air filter screens are nano-fine composite powders produced using cutting-edge technology and uniformly placed on the carrier surface using power coating or electrostatic spraying.There are paper-based photocatalyst filter screen, honeycomb photocatalyst filter screen, fibrous photocatalyst filter screen, gold photocatalyst filter screen and other types, Combined with ultraviolet light irradiation, It may quickly break down smoke, pollutants, and strange odors in the air to produce a cleansing and filtration effect.

Chemical catalyst and support materials

Foam metal has the characteristics of porous and large surface area, and is different from the commonly used non-metal and oxide catalysts and catalyst carriers. It has excellent mechanical qualities, high ductility, high heat conductivity, and is simple to manufacture into a variety of shapes. The porous foam metal has multiple openings and a broad application range. It demonstrates good hydrodynamic qualities. As a result, it has a lot of benefits when catalyzing the reaction of gas and liquid. Foam metal can be employed as a carrier or as a catalyst in a catalytic reaction.

Battery electrode material

The electrical conductivity and self-supporting capacity of the serial number are both present in the foam metal. It has a lot of pores, which can offer a lot of concentrated surface area. It is a great electrode material. It works well with a variety of batteries, fuel cells, air batteries, solar cells, and electrodes for electrochemical processes.

Heat exchange and adsorption materials

The foam metal has a large specific surface area, a three-dimensional porous structure, and good metal-to-metal thermal conductivity. The foam metal will be chilled or heated to achieve heat exchange when gas or liquid passes through the pores and either removes or increases heat. It functions well as a heating, heat-dissipating, and heat-exchange material.
