Copper powder sintering filter and copper powder sintering it has good permeability filtration performance and high filtration accuracy, can better withstand thermal pressure and impact, high strength, good plasticity, anti-oxidation, corrosion resistance. Good assembly, welding and machining, strong regeneration capacity, long service life, a variety of different porosity (28%-50%), aperture (4u-160U) and filtration accuracy (0.2um-100um), crisscrossing the aperture, can be used at 300 high temperatures, anti-fast, hot and cold. Than paper, copper wire mesh and other fiber cloth made of filter performance is superior, and easy to install and clean, mainly used to filter gas, liquid, fuel oil, in petroleum, chemical, automotive, tractors, aircraft, marine industry widely used, but also a large number of pneumatic, hydraulic circuit filter components. Copper powder sintering cartridges filter oil and water in the air and reduce snoise. In the pressure wind self-rescue device, its gas supply generally uses the mine pressure wind line, the pressure wind gas to reduce pressure, silence, flow adjustment, filter oil and water and other functions, to provide staff with fresh air. Copper sintering filter has air filtration and silence, and is widely used in pneumatic component gas source processors.
