Defining "Density" in Filtration Context
Dense wire meshes achieve porosity levels below 35% while maintaining structural integrity – a critical requirement where installation space is limited but particulate challenges are severe. Anping CREMOTIVE’s dense Dutch weaves (Plain/Twill variants) deliver micron-level retention in profiles as thin as 0.8mm through:
Wire Packing Density: Up to 2800 weft wires per meter
Precision Calendering: Post-weave compression to ±0.02mm thickness tolerance
Multi-Layer Bonding: Diffusion welding of 3-7 mesh layers into monolithic laminates
Performance Matrix
| Parameter | Plain Dutch Range | Twill Dutch Range |
|---|---|---|
| Absolute Rating | 1-100 µm | 0.5-40 µm |
| Permeability (air) | 10-200 m³/m²/h/kPa | 5-80 m³/m²/h/kPa |
| Maximum Pressure Drop | 15 bar (single layer) | 42 bar (laminated) |
| Temperature Cycling | -196°C to +550°C | -269°C to +650°C |
