Solvent free recombination produces longitudinal dead fracture
The main reason for this is that the tension of the substrate itself is uneven, and solvent-free equipment has strict requirements for the substrate. In view of the current situation of domestic raw materials, it can only be adjusted from the process.
A. Increase the unwinding and winding tension. The two should cooperate with each other to prevent contraction.
B. Increase the speed. Solvent free equipment is designed to meet the needs of high-speed production. Each guide roller has guide groove, and the guide of two adjacent rollers is opposite, which is to better play the role of flattening when high-speed composite. In addition, the high-speed coating can also enter the winding before the film is folded. At this time, it should be noted that in order to prevent poor coating effect at high speed, the temperature of COTS should be increased to ensure the quality.
