According to relevant sources, the current solution for adhesive penetration during hot pressing of flame-retardant plywood is:
Reason for occurrence:
1. The quality of the veneer is too poor, and the cracks on the back are too large;
2. The glue solution is too thin or the amount of glue applied is too large, and the aging time is too short;
3. The temperature of hot pressing is too high or the pressure is too high.
Solution:
1. Improve the quality of veneer and reduce the depth of back cracks;
2. Increase the concentration of glue solution, reduce the amount of glue applied, and extend the aging time;
3. Reduce the hot pressing temperature or decrease the unit pressure of hot pressing.
