Suiable for common PET/double-side tape/bopp tape/foam tape/paper sereis/pe protective film.
1. Automatic tension control.
2. Gravure coating or semiflexo coating.
3. Drying tunnel with sectional temperature control and recirculation adjustment.
4. Steel idle rollers inside the drying hood driven by independent motor.
5. Inner stainless steel frame covers of the coating section.
6. preading roller driven by independent motor,positioning pneumatically.
2.4. Coating job related product quality issues:
4) How to judge the bonding performance of the pole piece?
The material can not be removed, and taped to see how much residue, the positive electrode is greater than 1/3, and the negative electrode is greater than 1/2. It can be considered that the bonding is good.
5) How can I handle the correct handling of particles? Plug it with a stopper, if the pellets should be washed, wash the knife
6) What is the relationship between the quality of the knife and the quality of the coated pole piece?
Ensure uniform film density (interpolate the effect of film density on battery performance, capacity)
7) What is the importance of the gap adjustment between the back roller and the coating roller? Too big to carry the material, too small and easy to wear.
8) The importance of mixing.
Prevent slurry stratification and improve slurry consistency
Coating operation process --
? Pre-adjust the gap gap
1. Adjust the gap between the back roller and the coating roller. The gap is generally the thickness of the two layers of aluminum foil and copper foil (note: the adjustment of the roll gap on both sides is basically the same). The actual adjustment of the roll gap can be adjusted to adjust the specific parameters in the pushing device. The program is automatically saved once, and no adjustment is needed next time.
