Stainless steel sintering filter elements, such as stainless steel woven mesh and stainless steel punching mesh, are commonly used for water removal in front-stage heavy oil combustion systems and chemical liquid filtration. They have a filtration precision ranging from 2 to 200 microns and are made from materials like 304 and 316L, suitable for various industrial sectors such as electronics, petroleum, medicine, and food. These filter elements effectively purify water by removing suspended impurities (less than 2-5 mg/L).
It is important to replace blocked filter elements, deformed steel meshes, or frame filters in a timely manner to maintain hydraulic equipment's performance and service life. Regular maintenance of filters not only saves costs but also prevents hydraulic equipment failures that can have severe consequences. Therefore, proper maintenance and upkeep of stainless steel powder sintering filters are essential.
Stainless steel powder sintering filter elements are manufactured by molding stainless steel powder and subjecting it to high-temperature sintering for overall shaping. They possess several advantages, including high mechanical strength, temperature resistance, corrosion resistance, uniform aperture distribution, good air permeability, ease of cleaning and regeneration, and compatibility with welding and machining processes. By adjusting the powder particle size and process conditions, porous metal sintering filter elements with a wide range of filtration accuracies can be produced. These products find applications in catalyst recovery, chemical processing, medicine, beverage production, food processing, metallurgy, petroleum refining, environmental fermentation, and other fields. They are effective in removing gases, dust, bacteria, oil, noise, and providing flame resistance and gas buffering.
Key characteristics of stainless steel powder sintering filter elements include:
1. Stability in shape with superior resistance to impacts and alternating loads compared to other metallic materials.
2. Good air permeability and reliable separation efficiency.
3. Excellent structural strength suitable for high-temperature, high-pressure, and corrosive environments.
4. Particularly suitable for high-temperature gas filtration.
5. Availability in various shapes and precision products with the option to weld using different interfaces.
6. Performance attributes such as acid resistance, alkali resistance, high-temperature resistance, low-temperature resistance, fire resistance, and anti-static properties.
7. Suitable for working environments involving nitric acid, sulfuric acid, acetic acid, oxalic acid, phosphoric acid, 5% hydrochloric acid, molten sodium, liquid hydrogen, liquid nitrogen, hydrogen sulfide, acetylene, water vapor, hydrogen gas, carbon dioxide gas, and more.
The use of mesh plate sintering mesh includes:
1. Dispersed cooling in high-temperature environments.
2. Uniform gas application in the powder industry and fluidized plates in the steel industry.
3. Gas distribution in fluidized bed hole plate materials.
4. Blast furnace injection for pulverized coal flow transition and concentrated phase conveying systems.
5. Material filtration, washing, and drying in the pharmaceutical industry.
6. Catalyst support barriers.
7. Filtration in applications such as polyester, oil, food and beverage, chemical fiber products, water treatment, and gas filtration.
The sintering and heat treatment process for metal sintering mesh work involves loading, vacuuming, degassing, heating, argon filling, thermal insulation, cooling, and oven processes. The billet is initially pressed into the sintering tray or material box, which is made of high-temperature resistant materials like molybdenum sheet, heat-resistant steel, or graphite to prevent deformation during sintering.
