Post-curing problem
The main reason for the foaming after the tube is solidified is that the volatile content of the adhesive tape is too large, the winding temperature is low, the winding speed is fast, and the volatile matter of the adhesive tape is too low to be volatilized, so that it remains in the tube. When the tube is heated and solidified, its residual volatiles are swollen by heat so that the tube is foamed.

Solution: Control the volatile content of the tape, increase the rolling temperature appropriately, and slow down the rolling speed. The reason for the wrinkling after the tube is cured is that the tape contains a high amount of glue. Solution: Reduce the amount of glue in the tape and reduce the coiling temperature.

Withstand voltage problem
Causes: 1 When the coil is rolled, the tension of the tape is insufficient, the winding temperature is low or the winding speed is fast, so that the bond between the cloth and the cloth is not good, and the volatile matter in the tube is excessive; 2 the tube is not cured completely.

Solution: 1 Increase the tension of the tape, increase the rolling temperature or slow down the rolling speed; 2 Adjust the curing process to ensure the tube is completely cured.
