Causes:

1. The content of volatiles is too high after drying the impregnated paper

2. The solvent used for printing wood grain ink or dye is inappropriate

3. Moisture absorption (moisture regain) of adhesive film paper after soaking and drying

Solution:

1. Reduce the content of volatile matter after drying the impregnated paper

2. Change the solvent for ink (dye)

3. Pay attention to the storage of adhesive film paper, which can generally be covered with plastic cloth

The surface of the fire-proof plate and the surface of the decorative plate are cracked

Causes:

2. Incomplete curing of resin

3. The glue content of the surface film paper is too high

Solution:
