Excellent Penetration Rate Stainless Steel Fiber Sintered Felt

The excellent penetration rate stainless steel fiber sintered felt is an efficient filter material, mainly made of stainless steel fibers through a special process. These fibers are first laid nonwoven, then stacked and combined through a high-temperature sintering process to form a sintered felt with a unique three-dimensional network structure. This structure gives the sintered felt a high porosity, large specific surface area, and uniform pore size distribution, thus ensuring its excellent filtration performance.

Material properties

The material characteristics of the excellent penetration rate stainless steel fiber sintered felt determine its wide application in the field of filtration.

1. High porosity. The high porosity of the sintered felt ensures good air permeability and a large soiling capacity.

2. Uniform pore size. By controlling the fiber diameter and sintering process, a uniform and controllable pore size distribution can be achieved, resulting in high-precision filtration.

3. High temperature resistance. Stainless steel fiber sintered felt can maintain stable performance in high temperature environments and is suitable for filtration of high temperature gases and liquids.

4. Corrosion resistance. Due to its stainless steel material, sintered felt has good corrosion resistance and can resist the erosion of a variety of chemical media.

5. Mechanical strength. The structure of the sintered felt gives it a strong mechanical strength and is stable even under severe physical shocks or vibrations.

Application field

Due to its unique properties, the excellent penetration rate stainless steel fiber sintered felt is widely used in many industries.

1. Petrochemical. Used for the filtration of high-temperature, corrosive liquids in the refining process, and as a catalyst carrier.

2. Electronics industry. In the semiconductor manufacturing process, it is used for dust removal and purification of high-temperature gases.

3. Water treatment. As a pre-filtration material for ultrafilters, improve water quality and reduce the burden on subsequent treatment equipment.

4. Automotive and aviation. Used in the manufacture of fuel filtration and airbags to ensure the reliability and safety of the system.

5. Hydraulic system. As a filter element for hydraulic oil, it protects the system from particulate contaminants.

Production process

The production process of stainless steel fiber sintered felt mainly includes the following steps:

1. Fiber preparation. First, stainless steel fibers are prepared by cold drawing or rapid condensation, and the fiber diameter is selected according to the filtration accuracy requirements of the final product.

2. Non-woven felt. The prepared fibers are laid into a felt shape in a certain proportion and sequence to form a preliminary fiber layer.

3. Vacuum sintering. The laid fiber felt is placed in a vacuum furnace for high temperature sintering, so that the fibers are connected through sintering points to form a stable three-dimensional network structure.

4. Post-processing. The sintered felt is cut, folded or wound as needed to make filter elements of different shapes and sizes.

Maintenance and cleaning

As a washable filter medium, stainless steel fiber sintered felt has a long service life. Regular or irregular maintenance and cleaning is necessary to maintain its filtration efficiency and prolong its service life. Cleaning methods usually include backwashing, ultrasonic cleaning or chemical cleaning. The specific method depends on the degree of contamination of the sintered felt and the application environment.
