It's be mainly used for bopp film gelatinizing producing，The tape is mainly used to seal the box, seal the cover and bind the articles, and can also be used as office supplies.
Coating Machine - Process flow
Fourth, the process requirements: positive and negative electrode coating:
Foil requirements: aluminum foil: (degree × width) 18um × 500 (±1.0) mm areal density: 0.48 ± 0.02g / 100cm2 copper foil: wool foil: (degree × width) 9um × 500 (± 0.5) mm areal density: 0.98±0.04 g/100cm2 Light foil (degree×width) 9 um×500(±0.5)mm Area density: 0.87±0.04 g/100cm2
4 coating standards:
First dressing density: ±0.02g/100 cm2
Second dressing density: ±0.02g/100 cm2 Double-sided total dressing density: ±0.04 g/100 cm2
First dressing density: ±0.015 g/100 cm2 First dressing density: ±0.015 g/100 cm2
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.
