Chinese supplier ZSK Double Twin Extruder Parts Screw Segments For Lithium Battery Slurry

Screw elements are the core functional parts mounted onto the shafts inside the barrel of a parallel co-rotating twin-screw extruder. They determine how material is transported, mixed, melted, and pressurized along the extruder's length.

The specific type, length, pitch/angle and sequence of screw elements determine the extruder's performance for a given material and process (mixing quality, melting rate, devolatilization efficiency, pressure build-up, output rate). Configuring the screw profile correctly is crucial for optimal results.

• Superior Corrosion Resistance: Withstands highly corrosive fluorides (e.g., from PVDF binders) much better than standard steels, preventing pitting and degradation.
• Enhanced Wear Resistance: Significantly reduces abrasion from hard ceramic fillers (like Al₂O₃/SiO₂) commonly coated onto separators, extending element life.
• High-Temperature Strength: Maintains structural integrity and dimensional stability under the sustained high processing temperatures required for separator polymers.
• Reduced Metal Contamination: Minimizes metallic wear debris generation, crucial for preventing internal shorts in sensitive lithium-ion batteries.
