The sintered metal powder filter uses metal powder as a raw material without adding a binder. After cold isostatic pressing, it is formed by high temperature vacuum sintering. The pore size and distribution of the component can be adjusted by selecting the metal powder particle size and process parameters. Using the characteristics of the pore structure, material composition and compressive strength of different filter materials, we have developed a filter product that is finally suitable for the user.
The sintered metal powder filter can realize micro-scale precision filtration, which can separate solid particles in liquid and gas. When the fluid passes through a filter with a certain precision, the impurities are blocked on the surface of the filter to form a filter cake, and the pure fluid flows out through the filter element. The contaminated or contaminated fluid is cleaned to the state required for normal production to ensure that the downstream unit obtains a clean product or protects the equipment from normal operation.
Different from the non-metal sintered filter element, when the filter cake on the surface of the sintered metal powder filter core reaches a certain thickness, due to its high strength performance characteristics, the filter element can be backwashed or backflushed by a certain reverse pressure. Clean the filter element so that the filter element can be used again.
Sintered metal powder filters have the following outstanding properties:
1: Has good filtration performance
2: The shape is stable, the component has high strength;
3: High temperature resistance (up to 900 °C);
4: strong corrosion resistance;
5: Impact resistance, high alternating load;
6: good gas permeability and separation effect;
7: The backwashing effect is good, the components are easy to regenerate, etc.
