The surface of fire-proof board is layered with decorative board

Causes:

1. The volatile content of the adhesive film paper is too low, and the resin is locally cured when the adhesive film paper is dried

2. Insufficient resin content of adhesive film paper

3. Low pressure or insufficient hot pressing time

4. There are sundries between the adhesive film and the paper

Solution:

1. The content of volatiles shall be controlled not to be too low, the drying temperature shall not be too high, and the time shall not be too long to prevent local curing of the resin

2. Increase the glue content of adhesive film paper

3. Properly increase the pressure (including prolonging the heating time)

4. Pay attention to sundries during formwork laying
