Introduction and Performance Of Sintered Metal Powder Filter Element
May 20, 2025
Sintered metal powder filter element uses metal powder as raw material, without adding adhesive. After cold isostatic pressing, it is made by high-temperature vacuum sintering. By selecting the metal powder particle size and process parameters, the pore size and distribution of the element can be adjusted. The pore structure, material composition, compressive strength and other characteristics of different filter materials are used to develop the final filtration products that meet the needs of users.
Sintered metal powder filter element can achieve micron-level precision filtration and can separate solid particle impurities in liquid and gas. When the fluid passes through a filter element with a certain precision, the impurities are blocked on the surface of the filter element to form a filter cake, and the pure fluid flows out through the filter element, so that the contaminated or impure fluid is clean to the state required for normal production, so as to ensure that the downstream device obtains pure products or protects the normal operation of the equipment.
Unlike non-metallic sintered filter element, when the filter cake on the surface of the sintered metal powder filter element reaches a certain thickness, due to its high-strength performance characteristics, the filter element can be cleaned by backwashing or backblowing the filter element through a certain reverse pressure, so that the filter element can be used again.
Sintered metal powder filter element has the following excellent properties:
1: Good filtering performance (0.5~200µm);
2: Stable shape, high strength of the element;
3: High temperature resistance (can work at up to 900℃);
4: Strong corrosion resistance;
5: Impact resistance, high alternating load;
6: Good air permeability and separation effect;
7: Good backwashing effect, easy regeneration of the element, etc.
