Five-Layer Sintered Mesh
Five-Layer Sintered Mesh | Standard Stainless Steel Sintered Wire Mesh Filter
The Five-Layer Sintered Mesh, also known as the Standard Type Sintered Wire Mesh, is the most classic and widely used structure among sintered mesh filter materials. It is composed of five precisely selected layers of stainless steel woven wire mesh that are bonded together through vacuum sintering and diffusion bonding. Each layer serves a specific function, forming a single, strong, and porous metallic laminate with high mechanical strength, uniform pore size, and reliable filtration performance.
This structure combines excellent rigidity with stable permeability and is suitable for a wide range of industrial filtration and separation processes, especially in high-pressure or high-temperature environments.
Standard Five-Layer Structure
The typical configuration includes the following layers:
- Protective Layer – safeguards the filtration layer from direct mechanical damage.
- Dispersion Layer – evenly distributes the flow to optimize filtration efficiency.
- Fine Filtration Layer – provides precise particle retention and filtration accuracy.
- Support Layer – ensures overall mechanical strength and pressure resistance.
- Reinforcing Layer – enhances structural rigidity and durability during operation.
These five layers are diffusion-bonded together to form an integrated porous medium. The result is a filter material that offers high strength, excellent backwash performance, and consistent flow characteristics.
Advantages of Five-Layer Sintered Mesh
- High mechanical strength and structural rigidity – performs under high pressure and stress.
- Consistent filtration accuracy – uniform pore size ensures repeatable results.
- Excellent permeability with low pressure drop – enhances operational efficiency.
- Corrosion and high-temperature resistance – suitable for aggressive chemical environments.
- Easy cleaning and long service life – supports repeated backwashing and reuse.
- Versatile processing capability – can be cut, welded, rolled, or formed into filter elements.
