1. 150m/min high speed has already reached the international most advanced level.
2. Rewind and unwind both adopt double position and equip with semi-automatic to connect paper device, The machine can change the rolls of base material nonstop， It will reduce the waste.
3. When the double sides adhesive tape coat twice, it will effect the quality of products, but the technology of double sides coating meanwhile will solve the questions.
2.4. Coating job related product quality issues:
1) How to judge the quality of the coating?
The surface of the pole piece is flat, smooth, uniform in dressing, good in adhesion, dry, not to be stripped, not lost, lack of material, no dust, particles, no scratches, no bubble, the pole piece is a good pole piece, defective The bad pole piece.
2) What are the factors related to the uneven density of the film? How to adjust?
Irregularity and unevenness: the slurry is not uniform, the local solid-liquid ratio is large, the membrane is dense, and the solid-liquid ratio is small, the membrane density is small, and the stirring is enhanced. Vertical and horizontal unevenness: uneven seam, adjustable skew or coating roller, scraper has been deformed, should be adjusted or replaced. Horizontal and vertical unevenness: The speed of the coating roller or the back roller motor fluctuates and should be repaired.
3) How do you judge whether the pole piece has been dried and the temperature is too high? Non-stick rolls, no curling, sticky rolls are too cold, and curling is too hot.
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.
