Sintered multi-layer metal mesh is composed of laminated layers of woven wire cloth bonded by special calendaring and sintering in vacuum oven, to create a new filter material with higher strength and rigidity. It&＃039;s interlaced mesh forms an uniform and ideal filtration structure. As a new filter material, it not only overcomes the disadvantages of ordinary metal mesh, such as lower strength, poor integrity, unstable hole shapes, but has excellent performances such as high precision and strength, efficient flow restriction, machinablity and resistance to abrasion, heat and cold by reasonably arranging its porosity, permeability and strength. Therefore, it&＃039;s total performance has obviously advantages than sintered powder, ceramic, fiber cloth, paper and other filter material. Our sintered mesh has been widely used in many industries such as aerospace, aviation, petroleum, chemical, metallurgy, machining, pharmaceutical, food, synthetic fiber, film, environmental protection industries in respect of filtration and purification, gas-solid, liquid-solid, and gas-liquid separation, cooling, gas distribution, fluidization bed, air drilling, shock reducing, sound attenuation, inflaming retarding.
