Special Dense Mesh Separator

Special Dense Mesh Separator – Definition and Advantages

Introduction
Special dense mesh separators are custom-woven products designed for ultra-fine separation and support in electrochemical, battery and high-precision filtration systems. Anping CREMOTIVE Wire mesh products CO., LTD engineers these dense structures to exacting tolerances.

Key Features

• High Mesh Count: Weft and warp counts can exceed 200 wires per inch, creating sub-10 µm gaps.

• Uniform Thickness: Controlled weaving yields separators with thickness tolerances within ±5 µm.

• Dimensional Stability: Heat-set and pre-conditioned to prevent distortion under thermal cycling.

Materials and Coatings

• 316L Stainless Steel: Standard for general chemical resistance.

• Inert Coatings: PTFE or ceramic coatings enhance chemical inertness and reduce surface energy.

• Nickel Plating: Improves conductivity in battery separators.

Production Process

1. Micro-Wire Weaving: Ultra-fine wires require specialized precision looms and environmental controls.

2. Thermal Setting: Post-weave heat treatments stabilize the weave structure.

3. Surface Finishing: Coatings applied by dip, spray or vapor deposition to functionalize separators.

Applications

• Battery Technology: Lithium-ion and flow battery separators requiring high ionic conductivity and mechanical support.

• Fine Chemical Filtration: Separating catalysts and sub-micron particles in pharmaceutical reactors.

• Analytical Instruments: Sample clarification in chromatography and mass spectrometry prep.

Conclusion
Special dense mesh separators from Anping CREMOTIVE Wire mesh products CO., LTD combine ultra-fine weave, material control, and functional coatings to meet rigorous separation challenges.
