Detial of sintered metal porous filter

Datetime: Hits:

The sintered porous metal filter core structure usually includes a support layer, a working layer (filter layer), and a protective layer. In the filter layer, the filter screen is generally designed with an inverted cone (V-shaped) porous structure. With this structure, a multi-stage filtering effect can be achieved, so that impurity particles will not accumulate on the intercepted surface of the filter material too quickly, which is beneficial to improve the dust of the filter material and prolong the working life of the filter.
1. Structural characteristics of sintered wire mesh
The metal wire mesh is the key structure of sintered filtration, which directly affects the separation and overall operation effect of the metal filter. The selection of the filter itself is much more complicated, which involves various wire diameters, pore diameters, cavity areas, weaving technology and organization design, etc.
2. Performance of sintered metal fiber felt
With the successful application of the cluster wire drawing process, the development of sintered metal technology and the development of high-precision filter media have also been developed rapidly.
3. Sintered metal powder
Since the 1960s, in different applications and application environments, sintered powder porous filters have appeared, such as nickel-based alloys, chromium-nickel-iron alloys, titanium, stainless steel, and other corrosion-resistant and high-temperature resistant materials. Up to now, the mass production and application of sintered powder porous filters mainly include bronze, stainless steel, nickel and nickel alloys, titanium and so on.
