Twilled Dutch Weave Mesh To Microns

Twilled Dutch Weave Mesh to Microns

Precision size-grading is a key requirement in industries where sub-100 µm particulate control affects process yield and product quality. At Anping CREMOTIVE Wire Mesh Products CO., LTD, our Twilled Dutch Weave Mesh to Microns line addresses these needs by offering meshes with reliably measured slot widths down to 5 µm.

Production Methodology

• Fine-Wire Drawing: Stainless steel wire is drawn through progressively smaller dies to achieve diameters as low as 0.02 mm. Intermediate annealing ensures ductility.

• Weaving Technology: Air-jet looms equipped with micro-weave capabilities interlace fine warp wires over and under heavier weft wires. A programmable double-crimp mechanism locks each junction, safeguarding against wire migration.

• Inspection and Calibration: After weaving, each mesh panel is measured using laser diffraction and optical microscopy. Slot tolerance is maintained within ±10% for openings ≤20 µm and ±5% for larger openings.

Performance Metrics

• Cut-Point Precision: Retention ratings correlate directly to slot width; for example, a 10 µm slot mesh retains 95% of particles ≥10 µm in diameter under standardized test conditions.

• Flow-Rate Efficiency: Fine slots combined with high open-area ratios (20–30%) permit substantial throughput while achieving sub-micron separation.

• Thermal and Chemical Resistance: All meshes are passivated per ASTM A967 and operate continuously at temperatures up to 275 °C (530 °F).

Key Uses

• Pharmaceutical Filtration: Clarification of intermediates and sterile venting.

• Fine Chemical Recovery: Separation of catalyst fines and by-product removal in batch reactors.

• Analytical Sieving: Laboratory test sieves where high accuracy is required for particle-size distribution analysis.

• Microelectronics: Pre-filtration of chemicals and ultrapure water used in semiconductor fabrication.
