Stainless Steel Powder Sintered Material For Filtration

The Stainless Steel Powder Sintered Material For Filtration is a high-performance filter medium made by preparing stainless steel powder (common types include 304, 316L, etc.) through a precisely controlled process. This type of filter material is widely used in many fields such as chemical industry, medicine, food processing, water treatment, air purification, hydraulic system, etc.

 

Selection of stainless steel powder

Stainless steel powder is the basic raw material for the production of sintered filter materials. Common stainless steel types include 304, 304L, 316, 316L, etc., each of which has different corrosion resistance, heat resistance and mechanical properties. The following factors should be considered when selecting suitable stainless steel powder:

1. Corrosion resistance. 304 and 316 series stainless steel contain chromium and nickel, providing good general corrosion resistance. Among them, 316 series has enhanced resistance to chloride ion corrosion due to the addition of molybdenum, which is suitable for salty or acidic and alkaline environments.

2. Temperature adaptability. Different types of stainless steel have different maximum operating temperatures, which need to be selected according to the actual working conditions during the filtration process.

3. Mechanical properties. Such as strength, toughness, etc., need to be determined according to the filtration pressure and operating conditions.

4. Particle size distribution. The particle size of the powder directly affects the porosity and filtration accuracy of the final product. The smaller the particle size, the finer the pores that can be obtained.

5. Aerospace

Used for precision filtration of fuel, lubricating oil and gas to ensure the safe operation of aircraft.

6. Electronics industry

Used in high-purity gas filtration in semiconductor manufacturing and optoelectronics industry to prevent pollutants from affecting product quality.

 

Preparation process

The preparation process of the Stainless Steel Powder Sintered Material For Filtration mainly includes the following steps:

1. Raw material preparation. Select high-quality stainless steel powder as raw material. These powders usually have a specific particle size distribution to meet the requirements of subsequent filtration accuracy.

2. Sieving. Sieving the stainless steel powder to remove oversized or undersized particles to ensure uniform powder particle size, which is essential for controlling the filtration accuracy of the final product.

3. Molding. The screened stainless steel powder is pressed into the desired shape through a mold, such as tubular, plate, filter disc, filter rod, etc. This process determines the geometric size and structure of the filter element.

4. Sintering. The molded parts are sintered in a controlled high temperature environment. During the sintering process, neck growth occurs between the powder particles to form a solid connection, but a certain proportion of open porosity is retained, thereby creating a porous, microporous structure. The sintering temperature and time need to be precisely controlled to achieve the ideal density, strength and pore structure.
