The sintered powder metal filter is made of metal powder pressed through a mold and then sintered at a high temperature. It has the advantages of high mechanical strength, high-temperature resistance, good corrosion resistance, uniform pore size distribution, good air permeability, cleanable regeneration, welding, machining, etc.
The sintered powder metal filters are widely used in gas-liquid filtration and separation in the fields of the chemical industry, medicine, beverage, food, metallurgy, petroleum, environmental protection and fermentation, dust removal, sterilization, and oil mist removal of various gases and steam; gas buffer, etc.
Metal powder serves as the only raw material for the sintered metal powder filter; no binders are used. It is generated by cold isostatic pressing and then sinters at high temperatures. By adjusting the process parameters and metal powder particle size, the pore size and distribution of the component can be changed. Utilize the pore structure, material composition, compressive strength and other characteristics of different filter materials to develop filter products suitable for users. Product parameters Material: stainless steel powder, brass powder, titanium powder Diameter: Length: 5 inches (125mm) 10 inches (250mm) 12 inches (300mm) 20 inches (500mm) 30 inches (750mm) 40 inches (1000mm) Interface form: M20 M30 222 226 Filtration accuracy: 0.45 micron 1 micron 3 micron 5 micron 10 micron 20 micron 30 micron 50 micron 80 micron 100 micron Features Strong resistance to corrosion An inert metal with exceptional corrosion resistance is titanium. Strong alkali and strong acid media can be filtered using the titanium metal rod filter element. It has a wide range of applications in the chemical industry and in the filtering of the pharmaceutical industry's organic lysozyme production process. Good tolerance to high temperatures The titanium filter element has a high temperature resistance that goes up to 300C. In operational situations with high temperatures, this function is frequently used. The temperature resistance of the filter element made of polymer materials is normally limited to 50 C. The support and filter membranes will alter if the temperature goes beyond 50 C. It is frequently employed in the filtration of high-temperature liquids and steam filtration (steam filtration in fermentation processes), despite having a significant accuracy variance. Superior mechanical qualities With external pressure of 20 kg and internal pressure of 10 kg of destructive force, the titanium rod filter element has strong mechanical qualities and may be utilized in high pressure and quick filtration processes. The pore size of other polymer filter components will fluctuate or even break down when the external pressure is more than 0.5 MPa. Good regeneration Due to its superior corrosion resistance, high temperature resistance, and high strength performance, titanium rod filters have a good regeneration effect. There are two types of regeneration: chemical regeneration and physical regeneration treatment. Physical regeneration method: (1) Pure water recoil (2) Steam blowback (3) Ultrasonic cleaning Chemical treatment method: (1) Alkaline washing (2) pickling Applications Catalyst filtration and separation; Filtration of fluidized bed tail gas in petrochemical facilities and of high-temperature gas in the petrochemical industry; High-temperature flue gas purification in the metallurgical industry;

Products Description Sintered copper powder filter element is also called sintered copper. Like titanium and stainless steel powder sintered filter elements, it is also a breathable porous material formed by molding, isostatic pressing, etc., and then sintered by high temperature vacuum. It is a new type of material used in filtration and high-tech industries. Due to the advantages of stable pores, good strength, large amount of dirt, can be directly processed on the substrate, can be cleaned, and can be customized according to the required shape and size, sintered copper powder filter element has been widely used in pneumatic cylinders, electronic accessories, hydraulic filter elements, air dust removal, and gas distribution. , heat sink, mold making and other industries. The selection of precision is very critical In the process of using the sintered copper powder filter element, the selection of precision is very critical. If you choose a product with a smaller precision, if there is no corresponding pressure, the product flow will decrease and cannot meet the flow requirements; if you choose a product with a higher precision, it will It cannot intercept the required impurity particles, and cannot achieve the effect of filtering or dust removal. If it is used in a high temperature environment, it will also have a certain impact on the performance of the product. Features 1. Sintered copper powder filter element has stable penetration and high filtration accuracy; 2. Can better withstand thermal pressure and impact; 3. High strength, good plasticity, anti-oxidation, corrosion resistance, good assembly; 4. Strong regeneration ability and long service life; 5. Sintered copper powder filter element is resistant to rapid cooling and rapid heat, and has better performance than filters made of paper, copper wire mesh and other fiber cloth, and is easy to assemble, disassemble and clean; 6. It can work at higher temperature and in corrosive medium, and can be welded, bonded and machined. Main application of the product 1. Pneumatic valve cylinders and other pneumatic components are used to filter air, remove impurities in the air or gas distribution, decompression, interception, etc., and are fixed and installed by interference, stamping, screwing, threads, and clamps. 2. Oil-gas separation, solid-liquid separation, and oil-removal impurity filtration and separation, according to experience, can operate continuously under a pressure of 20Mpa, and can effectively remove impurities in the pore size according to different conditions of precision and pressure.
