High Porosity Stainless Steel Fiber Sintered Felt

The high porosity stainless steel fiber sintered felt is a kind of filter material made of extremely fine metal fibers by non-woven laying, stacking and sintering at high temperature. It has large pollution holding capacity, high filtration accuracy, long replacement cycle, high porosity and excellent penetration rate.

 

Performance features

The high porosity stainless steel fiber sintered felt has a variety of excellent performance features, which make it widely used in many industrial fields.

1. High strength

Due to the high strength of the stainless steel fiber itself and the stable sintered joints formed during the sintering process, the sintered felt has high mechanical strength.

2. High temperature resistance

Stainless steel fibers can maintain their structural and performance stability in high-temperature environments, so sintered felts can be used under high-temperature conditions.

3. Corrosion resistance

Stainless steel has good corrosion resistance, so sintered felt can be used for a long time in corrosive environments such as acid and alkali.

4. High filtration accuracy

By controlling the diameter of the fiber and the pore size of the sintered felt, extremely high filtration accuracy can be achieved, effectively removing tiny particles from the fluid.

5. Large pollution capacity

The sintered felt with multi-layer structure can form a porous layer, which not only improves the filtration accuracy, but also increases the amount of dirt and prolongs the service life.

6. Good permeability

The high porosity of the sintered felt ensures good permeability, maintaining a large flow rate even at high pressure differences.

Preparation method

The preparation of high porosity stainless steel fiber sintered felt usually involves the following steps:

1. Fiber preparation

First, stainless steel fibers with a diameter of microns need to be prepared. These fibers can be prepared by methods such as rapid condensation, rapid condensation and silk rejection, or electrochemical deposition.

2. Fiber cutting

The prepared stainless steel fiber needs to be cut into small segments of a certain length for subsequent laying and sintering.

3. Non-woven laying

The cut stainless steel fibers are evenly laid on the substrate to form one or more layers of fiber felt. This process needs to ensure that the fibers are evenly distributed to avoid uneven performance of the sintered product.

4. Stacking

If you need to prepare a sintered felt with a multi-layer structure, you need to stack fiber felts of different apertures together to form a pore layer, which can improve the filtration accuracy and the amount of dirt.

5. High-temperature sintering

Finally, the laid fiber felt is placed in a high-temperature furnace for sintering. During the sintering process, the contact points between the fibers will fuse together to form a stable sintered joint, resulting in high structural stability and mechanical strength of the entire fiber felt.

 

Relevant standards and norms

In China, the production and use of high porosity stainless steel fiber sintered felt follows a series of national standards and industry standards. For example, GB/T 2010-2016 is a national standard on stainless steel fiber sintered felt, which specifies the technical requirements, test methods, inspection rules and requirements for marking, packaging, transportation and storage of products. In addition, there are industry standards for specific application fields, such as aviation, aerospace, chemical industry and other industries may have stricter standards and specifications.
