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.

Parameters

Performance characteristics

The Stainless Steel Powder Sintered Material For Filtration exhibits a series of excellent properties due to their unique manufacturing process:

1. High filtration accuracy

With fine powder particle size control and precise sintering process, micron and even submicron filtration accuracy can be achieved to meet high purity requirements.

2. High strength and stability

The sintered body has good integrity and mechanical strength, can withstand high pressure difference and impact, and will not deform after long-term use.

3. Corrosion resistance and high temperature resistance

Stainless steel itself has excellent corrosion resistance and high temperature resistance, and is suitable for various harsh environments.

4. High flux and low pressure drop

The optimized pore structure design ensures good flowability and maintains low pressure loss even at high filtration efficiency.

5. Easy to clean and regenerate

The pore structure is easy to backwash, chemically clean or clean by other physical methods, extending the service life.

Application fields

The Stainless Steel Powder Sintered Material For Filtration is widely used in multiple industrial fields:

1. Chemical and petrochemical

Used to remove harmful impurities and protect equipment in chemical reactions, gas purification, solvent recovery and other processes.

2. Food and beverage

Used to filter alcohol, beverages, edible oil, etc. to ensure food safety and product quality.

3. Pharmaceutical industry

Used for aseptic filtration of liquids and gases in the pharmaceutical process to ensure the purity of drugs.

4. Water treatment

Used in drinking water purification, wastewater treatment, seawater desalination and other fields to remove suspended matter, bacteria and viruses.

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.
