Multi-layer composite structure
Sintered wire mesh cartridge is made of 5-6 layers of metal wire mesh (e.g. SUS304/316L) with different mesh counts composited by vacuum sintering process, and the typical structure includes protective layer, filtration layer, dispersion layer and support layer.
Protective layer: the outer layer of coarse mesh (such as 8-12 mesh) to resist mechanical impact.
Filter layer: the middle fine mesh achieves a filtration precision of 1-300μm.
Support layer: inner coarse mesh provides compressive strength (up to 8.5MPa).
Sintering process: metallurgical bonding under high-temperature vacuum environment, no adhesive between layers to avoid the risk of falling off.

Chemical cleaning: 5% NaOH solution immersion (corrosive media), citric acid cleaning (organic residue).
High temperature treatment: 600℃ baking to remove polymer residue, need to avoid direct contact with open flame.
Fluid characteristics: 316L/2205 for corrosive liquids, titanium alloy for high temperature gases.
Working pressure: 5-layer structure for regular working conditions, 6-layer composite for high-pressure systems (such as hydraulic).
Filtration precision: 1-100μm (pharmaceutical), 50-300μm (petrochemical crude filtration).
Avoid the use of strong acids (nitric acid, hydrochloric acid), neutral cleaning agents are recommended.
Regularly check for surface damage (e.g., deformation of holes due to collision) and replace damaged cartridges in a timely manner.
Match with self-cleaning system (mechanical scraper or backwash module) to reduce manual intervention.
Stainless steel sintered mesh filters can continuously work in temperatures ranging from -200℃ to 650℃. Special materials like titanium alloy can resist temperatures up to 800℃ in the short term, while PTFE materials can withstand up to 200℃.
