Coating Machine - Process flow
Fifth, the common problems of coating and treatment methods:
13. The coating tension is set at 1.8 and the negative is set at 2.8.
14. When the thickness is not uniform, adjust the distance between the scraper and the test roll.
15, the front and back are inconsistent, adjust the coating length and tracking coating length.
16. The tension of the initial roll diameter should be adjusted each time the roll is changed.
17. Rounding or other issues are well marked.
Coating Machine - matters needing attention
1. The maximum temperature of the positive electrode coating should not exceed 125 oC on one side. The single surface is not easy to dry. The non-stick roller is the standard. The reverse speed is slow and thoroughly dried.
2. The temperature of the single side of the negative electrode should not exceed 105 oC, and the temperature of double coating should not exceed 110oC.
3. The coated pole piece must be completely baked. If it does not dry or has the phenomenon of stripping, the temperature of the temperature zone can be properly adjusted, the temperature can be lowered, the pole piece can be stripped, the temperature can be lowered, and the temperature can be raised.
4. The density is adjusted by adjusting the screw.
5, the thickness is adjusted by adjusting the screw, so that the two sides reach a consistent speech.
6. Adjust the speed and temperature to achieve the best coating.
