1.Main engine & pump full-automatic tracking system and constant tension control system, no matter ensure the coating stability, improve the material compound roughness.
2.Double position for taking up roller and full automatic not reduce changing roller, greatly improve the equipment operation and produce efficiency.
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.
