Mesh-Free Stainless Steel Sintered Felt

The mesh-free stainless steel sintered felt is a high-performance filter material, mainly made of micron-scale stainless steel fibers through non-woven paving, stacking and high-temperature sintering processes. This material has been widely used in many industries due to its unique structure and excellent properties.

 

Features and performance

The main features of the mesh-free stainless steel sintered felt include:

1. High filtration accuracy

The mesh-free stainless steel sintered felt can achieve extremely high filtration accuracy, which means it can effectively intercept extremely fine particles and ensure the purity of the filtered medium.

2. Large sewage holding capacity

Due to its multi-layer structure design, the mesh-free stainless steel sintered felt has a large dirt holding capacity, which can continue to work without frequent replacement, reducing maintenance costs.

3. Corrosion resistance and high temperature resistance

The mesh-free stainless steel sintered felt can withstand the corrosion of corrosive substances such as nitric acid, alkali, organic solvents, and pharmaceuticals, and can be used for a long time at temperatures up to 600 °C, which makes it perform well in harsh working environments.

4. High void and excellent penetration rate

The high void ratio of the mesh-free stainless steel sintered felt ensures a good penetration rate, maintains a large flow rate even at high pressure difference, and reduces pressure loss.

5. Strong machinability

The mesh-free stainless steel sintered felt can be subjected to folding treatment to increase the filtration area, and can also be processed by welding to meet the needs of different application scenarios.

6. Washable and regenerable

After being used for a period of time, stainless steel sintered felt can be cleaned to restore its filtration performance and achieve material recycling, which helps to reduce long-term operating costs.

Manufacturing process

The manufacturing process of mesh-free stainless steel sintered felt mainly includes the following steps:

1. Fiber preparation

First, stainless steel is made into micron-sized fibers by rapid condensation or other methods.

2. Non-woven laying

The prepared stainless steel fibers are laid on the non-woven fabric in a certain proportion and manner to form a preliminary felt layer.

3. Stacking

The felt layers of different apertures are stacked together to form a multi-layer structure with a hole layer.

4. High-temperature sintering

The stacked felt layer is placed in a high-temperature furnace for sintering to fuse the contact points between the stainless steel fibers to form a solid three-dimensional network structure.

5. Post-processing

After sintering, the felt needs to undergo post-processing processes such as cooling, cutting, and cleaning to ensure the quality and performance of the product.

 

Application field

The mesh-free stainless steel sintered felt is widely used in the following fields due to its excellent filtration performance and corrosion resistance:

1. Chemical industry: used to filter various chemicals, especially in high-temperature and corrosive environments.

2. Oil and gas industry: used in processes such as oil-water separation and gas purification.

3. Pharmaceutical industry: used for liquid filtration in the pharmaceutical process to ensure the purity of the drug.

4. Food and beverage industry: used to filter liquid foods such as cooking oil, juice, alcohol, etc.

5. Environmental protection field: used in environmental protection projects such as wastewater treatment and air purification.

6. Aerospace: used for filtration of aircraft fuel systems and other precision equipment.
