Sintered porous filter uses metal powder as raw material without adding adhesive. Firstly, metal powder is compacted and formed by taking liquid as pressure medium at the room temperature, and then is high temperature vacuum sintered. When the heating temperature is lower than the melting point of the main composition, bonding and other physical and chemical action occur between particles, sintered materials with required strength and properties are obtained. Equipped with different connectors, sintered porous filter is obtained, featuring stable shape, good air permeability and great separation effect.
The pore size, distribution, strength and air permeability of the sintered porous filter depends on the powder fineness, compacting and sintering processes. Sintered porous filter achieves micro-rating fine filtration to remove solid particle impurities from liquids and gases.
The most commonly used sintered metal materials are stainless steel and brass. In addiction, titanium, nickel, Monel and other materials are available upon request.
Sintered porous filter can work with a variety of connectors and can be customized upon request.
