GKD-Sintered wire cloth laminates are stainless steel wire mesh layers which are permanently bonded by diffusion annealing. Depending on the stability and filtration requirements, the wire mesh layers can also be combined with perforated plates or metal fiber felt. While highly mechanically stable, the diffusion annealing maintains the filtration characteristics of a fine filter cloth. The flexible fabrication method enables GKD to manufacture and develop sintered mesh custom to each customer’s specifications and needs, even in small lots. GKD sintered laminate consists of five layers of selected metal meshes which are calendered several times and then bonded into one unit through diffusion annealing. Using sintered laminate offers several advantages: extremely high rating in mechanical stability and having no displacements within the wire cloth construction, sintered laminate also offers high filtration capacity due to surface filtration, and since there is no penetration into the filter media, sintered laminate is also easy to clean. Because sintered laminate is made from stainless steel (AISI 304, 316) and other special alloys, it is extremely resistant to corrosion, wear resistant, and operates in temperatures from -50°C (-58°F) to +550°C (1022°F). Other features include exact pore size distribution and permeability characteristics; excellent processing possibilities (“sheet metal characteristics”); the ability to produce custom mesh, specific to the customer’s specifications; and the ability to process into filter candles, circulars, discs, etc. as needed. Typical applications for GKD-sintered laminate include filtration of polymers, food, chemicals, pharmaceuticals and cosmetics, hydraulic oils and fuels, water, and discharge. It is also used for fluidization of bulk materials in gravity conveyors, wagons, bulk material, conveyors, storage silos, driers, and coolers.
