High-Flow PP Filter Cartridge for Lithium Battery Circulating Alkaline Liquid

Product Details

High-flow PP filter cartridge for lithium battery circulating alkaline liquid is a high-flow filtration component designed for circulating alkaline liquid systems in lithium battery production. It is suitable for working conditions with high alkalinity, large flow and trace impurities, which can effectively intercept suspended particles and impurity debris in alkaline liquid, maintain the purity and process stability of circulating alkaline liquid, reduce equipment loss, and adapt to continuous production lines.

Core Materials

Filter Media: Polypropylene (PP) ultra-fine fiber with gradient aperture depth structure, formed by hot-melt welding without adhesive, no fiber shedding, suitable for strong alkaline environment.

Structural Parts: End caps, inner core and outer support skeleton are all made of polypropylene (PP), with acid and alkali resistance, stable structure, suitable for long-term circulating working conditions.

Seals: EPDM, FKM O-rings are optional, with good sealing adaptability to prevent bypass leakage.

Process Features: Integral hot-melt welding without secondary pollution; large-diameter pleated design with large effective filtration area and high dirt-holding capacity.

Technical Specifications

Filtration Rating: Standard 1μm–100μm (1/3/5/10/20/30/50/75/100μm), customizable.

Dimensions: Standard lengths 20/40 inches; outer diameter φ152mm (for high flow), interfaces available in flat seal / double open end, compatible with high-flow filter housings.

Operating Temperature: ≤80°C, suitable for conventional circulating temperature range of alkaline liquid.

pH Range: 1–13, compatible with strong alkaline circulating liquid for lithium batteries.

Max. Operating Differential Pressure: 2.4bar (80°C), 4bar (21°C); initial differential pressure ≤0.02MPa, low pressure drop operation.

Effective Filtration Area: 40-inch ≥1.8m², single cartridge flow rate up to 30–50m³/h (water-based), meeting large-flow circulation requirements.

Functions & Applications

Lithium Battery Circulating Alkaline Liquid Filtration: Intercept graphite debris, metal microparticles, suspended solids and other impurities in alkaline liquid, maintain cleanliness, and stabilize electrode treatment and cleaning processes.

Applicable Scenarios: Alkali washing process for cathode and anode sheets, circulating alkaline liquid regeneration system, large-flow alkaline liquid conveying filtration, circulating filtration unit of continuous lithium battery production line.

Matching Use: Can be used alone as security filtration or combined with pre-treatment to form a multi-stage filtration system to protect downstream pumps, pipelines and precision equipment.
