Sintered Square and Dutch Woven Mesh - Five Layers
Five-layer sintered mesh is a standard combination of five layers wire meshes with different openings and diameters through sintering (diffusion-bonding) in vacuum, which improves the characteristics of stainless steel woven wire mesh. By bonding the contact points of different wire meshes together, five-layer sintered mesh has become an integrated porous material with enhanced mechanical strength, high permeability and better structural integrity, because the sintering process remains the good filtration rating of the finest mesh layer, also the mechanical strength of the coarser support layers. Besides all of that, heat and pressure are combined to create molecular diffusion-welds at every intersection of the wire mesh where the wires cross over and under one-another, which in turn enhances the temperature and pressure resistance of the sintered mesh. For its distinct features, five-layer sintered mesh is widely used for diffusing, breather vents, filters in many areas such as gas distribution, polyester filtration, water treatment, etc.

It can be cleaned by countercurrent water, filtering, ultrasonic, melting, baking, etc. It is especially suitable for backwashing.
Backwashing of sintered mesh is achieved by pressurising the mesh from within the machine and quickly opening the backwash square valve during the backwash. The backwash generates a high reverse homeopathic pressure differential, which effectively removes contaminants from the element surface.
Sintered mesh is made from multiple layers of metal mesh through a diffusion solid solution sintering process. Its basic process flow is:
Mesh structure design. The sintered mesh must meet the requirements of the filter system. Therefore, before production, it is necessary to reasonably customize its filter rating, thickness, number of layers, single-layer metal mesh structure, and material to ensure it meets the needs of the existing current filter systems.
Mesh pre-treatment. Stack single-layer metal mesh.
Ultrasonic cleaning. Sintered mesh has good backwashing properties. Through ultrasonic cleaning, excess impurities on the surface of the single-layer metal mesh can be removed, making its surface smooth and facilitating subsequent sintering.
Vacuum sintering. The cleaned stacked sintered mesh is placed in a vacuum sintering furnace for pressing. When the temperature reaches 1,100 °C, a diffusion solid solution process is employed to ensure that the mesh opening channels are not easily deformed and that the surface is smooth, thereby guaranteeing stable filtration precision of the sintered mesh. At the same time, after the pressing and sintering process, the sintered mesh possesses high mechanical strength and overall rigidity;
Cutting. When the sintering is completed, suitable dimensions are cut out through machining.
