High-Class Stainless Steel Powder Sintered Filter Material

The high-class stainless steel powder sintered filter material is a filter material made of stainless steel powder through a high-temperature sintering process. This material is widely used in the purification process of powders, liquids and gases in chemical, petroleum, automobile manufacturing, aviation and other industrial fields due to its excellent corrosion resistance, high temperature resistance and high mechanical strength.

Raw materials and performance

1. Raw materials

The raw materials of the high-class stainless steel powder sintered filter material are mainly stainless steel powder. Commonly used stainless steel materials include 304, 316, 316L, etc., among which 316L has better corrosion resistance. Factors such as the particle size, shape and purity of stainless steel powder will affect the performance of the final filter material.

2. Performance

The high-class stainless steel powder sintered filter material has the following properties:

- Corrosion resistance. Stainless steel powder sintered filter material can work stably in most corrosive environments and is suitable for a variety of chemical media.

- High temperature resistance. It can withstand high temperatures and is suitable for filtration in high temperature environments.

- High porosity. Filter materials with different porosities can be manufactured to meet the flow and pressure drop requirements of different applications.

- High mechanical strength. It can withstand high pressure difference during the filtration process and is not easily damaged.

- Recyclable use. After use, the filter material can restore its filtration performance by cleaning and other methods, and can be recycled.

- Diversity. It can be made into different shapes and sizes according to needs, such as powder, plate, mesh, etc.

Manufacturing process

The manufacturing process of the high-class stainless steel powder sintered filter material mainly includes powder preparation, molding, sintering and other steps.

1. Powder preparation

Select suitable stainless steel powder and prepare it by atomization, reduction or other methods. The powder prepared by atomization has good dispersion and uniformity and is suitable for large-scale production. The powder prepared by reduction method has high purity, but the preparation process is more complicated.

2. Molding

The powder is compressed into a blank of the required shape and size. Molding methods include pressing molding, extrusion molding, injection molding, etc. Pressing molding is suitable for filter materials with simple shapes, extrusion molding is suitable for filter materials with complex shapes, and injection molding is suitable for the production of micro filter materials.

3. Sintering

The powder particles are melted together at high temperature to form a filter material with a certain pore structure and strength. The sintering process is divided into three stages: pre-sintering, heat preservation sintering and final sintering. The purpose of pre-sintering is to eliminate the volatile matter in the powder, the purpose of heat preservation sintering is to make the powder particles fuse, and the purpose of final sintering is to further improve the mechanical strength of the filter material.

Development Trends

1. Optimize manufacturing process and reduce costs.

2. Improve pore structure control technology and optimize filtration performance.

3. Develop new stainless steel materials to improve corrosion resistance and high temperature resistance.

4. Expand application areas to meet more market needs.

5. Strengthen industry-university-research cooperation and promote technological innovation.
