The copper powder sintered filter cartridge is a filtering component made from copper alloy powder through high-temperature sintering. Below is a detailed introduction to it:
I. Characteristics
High Filtration Accuracy: The filtration accuracy of the copper powder sintered filter cartridge typically ranges from 5 to 50 micrometers. The pores are stable, and there is no change in pore size due to pressure variations. The filter cartridge can effectively remove suspended solids and particles, exhibiting excellent filtration accuracy and purification performance.
Good Air Permeability: The filter cartridge is entirely composed of spherical powder, resulting in a high porosity and uniform, smooth pore sizes. It has low initial resistance, is easy to back-blow, has strong regeneration capabilities, and a long service life.
High Mechanical Strength: The copper powder sintered filter cartridge possesses high mechanical strength, good rigidity, and plasticity. It does not require additional skeletal support and protection, making installation and use simple and maintenance convenient.
Corrosion Resistance and Oxidation Resistance: The filter cartridge is resistant to oxidation and corrosion, has good assembly properties, and can withstand thermal stress and impact well.
High Material Utilization Rate: The copper powder sintered filter cartridge is formed in one piece without the need for cutting, resulting in a high effective utilization rate of raw materials and maximum material savings. It is particularly suitable for components with large batches and complex structures.
Heat Shock Resistance: The filter cartridge is suitable for higher working temperatures and heat shock resistance. It can operate at higher temperatures and in corrosive media, and can be welded, bonded, and machined.
II. Manufacturing Process
Copper Powder Selection: High-purity copper powder is selected as the raw material, with uniform particle size and smooth surface.
Material Mixing: The copper powder is mixed with a small amount of additives (such as activated carbon) to improve the filter cartridge's adsorption capacity and filtration effect.
Molding and Pressing: The mixed material is placed in a mold and subjected to certain pressure and temperature conditions to form the initial shape of the filter cartridge.
Sintering Treatment: The molded filter cartridge is placed in a furnace for high-temperature sintering treatment, allowing the copper powder particles to melt together and form a dense structure, enhancing the filter cartridge's strength and wear resistance.
Surface Treatment: After sintering treatment, the filter cartridge surface usually undergoes special treatments such as coating or plating to increase its surface activity and corrosion resistance.
III. Application Scope
The copper powder sintered filter cartridge is widely used in pneumatic components, the chemical industry, environmental protection, and other fields, specifically including but not limited to:
Pneumatic Components: The filter cartridge has air filtration and silencing functions, and is widely used in pneumatic component air source processors.
Chemical Industry: It is used for filtering gases, liquids, and fuel oils, and is widely applied in industries such as petroleum, automobiles, tractors, airplanes, and ships.
Environmental Protection: It is used for filtering impurities and oil in air compressors, as well as for sterile air filtration in beer, pharmaceutical, and brewing industries.
Additionally, the copper powder sintered filter cartridge can be used for medium purification and flow control in lubricating oil, fuel oil, and hydraulic and pneumatic systems, compressed air oil removal and purification, crude oil sand removal filtration, nitrogen and hydrogen (sulfur-free) filtration, pure oxygen filtration, bubble generators, and gas distribution in floating beds.
In summary, the copper powder sintered filter cartridge plays an important role in industrial production due to its unique properties and wide range of applications.
