Sintered Porous Filter
Sintered porous filter use metal powder as raw material without adding binder. First, the metal powder is compacted and molded at room temperature with a liquid as the pressure medium, and then vacuum sintered at high temperatures. When heated below the melting point of the main component, bonding and other physical and chemical interactions occur between the particles, resulting in a sintered material with the desired strength and properties. By equipping different connectors, sintered porous filters with stable shape, good permeability and good separation effect are obtained.
The pore size, distribution, strength and permeability of sintered porous filters depend on the powder fineness, compaction and sintering process. Sintered porous filter achieve micron fine filtration to remove solid particle impurities from liquids and gases.
The most commonly used sintered metal materials are stainless steel and brass. In addition, titanium, nickel, monel alloys and other materials are available upon request.
