1. It is provided with anilox roller plus blade for coating mode, and also provided with many selection opportunities of anilox roller with various coating amount.
2. It is provided with separate five-section type constant temperature drying system using infrared stainless steel heating tube plus beating wind, as wellas adjustable interior circulation air draining and suction devices. It is advantageous in strong wind-exit and wind entrance, helping drying thoroughly.
Coating Machine - Process flow
Fourth, the process requirements: positive and negative electrode coating:
Double-sided total dressing density:
1. The first coating length deviation is ≤ 2 mm, and the coating gap deviation is ≤ 1 mm. 2. The maximum misalignment between the second side and the first side is ≤ 1 mm.
3. The maximum deviation of the thickness of the coated single film is ≤3um, and the maximum deviation of the thickness of the double film is ≤6um. 4. The maximum deviation of the density of the coated single film is ≤ 4%, and the maximum deviation of the density of the double film is ≤ 8%. 5. The maximum error of coating tailing is ≤1mm.
6, the film surface should be flat, can not appear dry cracks, wrinkles, particles, streaks. 7. Coating width = single strip width multiplied by the maximum number of coatable sheets + 5 ~ 10mm.
Coating Machine - matters needing attention
7. When adjusting the gap between the coating roller and the back roller, the slurry on the coating roller should be wiped off without sticking the back roller. The parallel and the gap of the two rollers must be consistent (there must be a gap).
8. Immediately after each shift, clean the hopper, scraper, coating roller and back roller with alcohol or acetone. The surface must not be scratched or damaged.
9. Pay attention to keeping the back roller cylinder and linear slide clean and lubricated.
10. The bearing parts of the machine must be lubricated regularly, and the gear box must be changed or replenished regularly.
11. Once problems are found during the operation, they must be recorded and notified to the relevant departments for timely processing.
