Large Capacity Stainless Steel Fiber Sintered Felt

The large capacity stainless steel fiber sintered felt is a new type of porous material made of stainless steel fiber through grinding, lamination and high-temperature diffusion bonding (sintering). It has excellent strength and filtration function, mainly manifested in its high porosity, uniformly distributed pore size and large dirt holding capacity.

 

Physical properties

1. High porosity

The porosity of large capacity stainless steel fiber sintered felt can reach more than 80%, which makes it have a larger effective filtration area under the same volume, which helps to improve the filtration efficiency.

2. Controllable pore size

In production, the pore size can be controlled by adjusting the fiber diameter, laying density and sintering conditions to meet the needs of different filtration precisions.

3. Good permeability

Due to its unique pore structure, the fluid can pass quickly, reducing the pressure drop and increasing the processing capacity.

4. Excellent corrosion resistance

The stainless steel material gives the sintered felt good corrosion resistance and can be used in a variety of complex chemical environments.

 

Mechanical properties

1. High strength and durability

The fiber nodes in the sintered felt are firmly combined, which makes it have high tensile strength and durability, and can work stably in harsh environments.

2. Thermal stability

It has outstanding high temperature resistance and can be used for a long time in an environment up to about 600°C without deformation, which is suitable for high temperature filtration occasions.

3. Processability

Although it has high mechanical strength, stainless steel fiber sintered felt can still be post-processed by cutting, folding, stamping, etc. to adapt to different filter designs.

Application areas

1. Chemical liquid filtration

In the chemical production process, it can be used to filter impurities in raw materials, intermediate products or final products, such as catalyst removal, polymer filtration, etc.

2. Gas dust removal

It is used for high-temperature flue gas dust removal, such as coal-fired power plants, metal smelting, cement manufacturing and other industries, to effectively remove particulate matter in the exhaust flue gas.

3. Food and pharmaceutical industry

In the food and pharmaceutical industries, it is used to ensure the purity and safety of liquids and meet strict hygiene standards.

 

Manufacturing process

1. Raw material preparation

First, it is necessary to select stainless steel fibers of suitable wire diameter and length. These fibers are usually made of high-quality stainless steel materials such as 304 or 316L, with good corrosion resistance and mechanical strength.

2. Dispersion treatment

The stainless steel fibers need to be fully dispersed to ensure that the fibers can be evenly distributed during the subsequent laying process. This step has a decisive influence on the porosity and strength of the final product.

3. Laying and forming

The dispersed fibers are laid into a uniform mesh structure through special equipment. At this stage, the density of the fibers and the thickness of the mesh can be adjusted according to needs.

4. Sintering process

The laid mesh structure is sent to a high-temperature furnace for sintering. Under precisely controlled temperature and atmosphere, the fibers are diffused and bonded to form firm nodes, thereby producing a stable pore structure.

 

Maintenance and regeneration

1. Cleaning methods

Regular cleaning can effectively extend the service life of sintered felt. Depending on the pollutants, ultrasonic cleaning, chemical cleaning and other methods can be used.

2. Regeneration treatment

For severely clogged sintered felt, heat treatment or chemical treatment can be performed to restore some of its filtration capacity.

3. Storage and maintenance

When not in use, it should be stored in a dry and clean environment to avoid contact with corrosive substances and prevent mechanical damage.
