Primarily suitable for coating lithium-ion battery separators and their slurries.
Product Name & Model: Diaphragm Coating Machine
Product specifications: Length 3700mm × Width 1550mm × Height 1750mm
Compressed air: ≥ 0.5 MPa
Key Features: 1. Manual up-and-down winding; 2. Dual functionality—enabling both ceramic coating and oil-based PVDF coating; 3. Segmented tension control; 4. Automatic edge-tracking for unwinding and rewinding processes; 5. Manual threading capability; 6. Convenient cleaning of the coater tank with an external circulation interface; 7. Continuous coating or micro-convex reverse coating options; 8. Use of explosion-proof fans designed to withstand exposure to organic solvents; 9. Oven exhaust features a round interface for easy connection to external gas-discharge piping; 10. VDF coating unit is equipped with a protective cover to minimize environmental interference during coating (user-adjustable); 11. Protective guard on the diaphragm cutting blade prevents accidental injuries.
Technical Specifications: 1. Roller surface width: Max. 320 mm; 2. Coating substrates: PE and PP separators (material thickness: 7–25 µm); 3. Coating material viscosity range: 10–1000 CPS; 4. Coating thickness: Single-sided dry film thickness of 1–4 µm (adjustable—different specifications require replacing the coating roller, paired with a corresponding mesh roller); 5. Material width range: 100–250 mm; 6. Coating width range: 100–250 mm; 7. Winding and unwinding diameter of separator rolls: Max. Φ300 mm; 8. Core diameter for winding/unwinding: Φ3″; 9. Substrate weight capacity: Max. 50 kg; 10. Tension control range: Adjustable from 5 to 50 N, with control accuracy ≤1 N; tension setpoint deviation from actual value ≤3 N; 11. Machine speed: Max. 10 m/min, Min. 1 m/min—actual production speed depends on the specific coating process, substrate type, and drying conditions; 12. Guide rollers: Surface treated with hard anodized oxidation for enhanced durability; 13. Single-sided coating dry film tolerance: For gravure printing, dry film thickness accuracy is ±1 µm, ensuring no visible coating defects (subject to slurry consistency); 14. Guide roller installation accuracy: Parallelism ≤±0.1 mm, levelness ≤±0.05 mm; 15. Guide roller material: Aluminum guide rollers with anodized surface treatment; 16. Equipment travel speed: 0–10 m/min; 17. Winding alignment accuracy; 18. Ceramic coating: Single-sided coating with thickness ranging from 1 to 4 µm; 19. PVDF coating: Double-sided coating with a total thickness of 2–6 µm.
