1. Causes of Combi Core Film Faced Plywood bubbling and partial degumming: The veneer has too high moisture content or uneven drying, too much glue, too fast pressure reduction speed or too high hot pressing temperature, insufficient resin condensation, Insufficient heat pressing time.
Solution: Control the moisture content of the veneer within the range of 8-12%, control the amount of glue to meet the process requirements, the speed of the second stage of depressurization should be slow, the hot pressing temperature should be appropriately lowered, check the quality of the resin, and extend the hot pressing appropriately time.

2. The reasons for the low bonding strength or degumming of Combi Core Film Faced Plywood: poor glue quality, insufficient glue or uneven glue, aging time is too long, glue is dry or aging time is too short, glue is not A continuous film is formed, the pressure is insufficient, or the temperature is too low, or the heat pressing time is too short, the veneer burr and groove marks are too deep, the quality of the peeling is poor, and the moisture content of the veneer is too high
Solution: Check the quality of glue, pay attention to the amount of glue applied moderately and evenly, mainly control the aging time, appropriately increase the pressure and temperature, or extend the hot pressing time, improve the quality of veneer peeling, and control the moisture content of the veneer to not exceed the stipulation Range.

3. The reasons for the penetration of Combi Core Film Faced Plywood: the quality of the veneer is too poor, the back crack is too large, the glue is too thin or the amount of glue is too large, the aging time is too short, the temperature of the hot pressing is too high or the pressure is too high Big.
The solution: improve the quality of the veneer, reduce the depth of the back cracks, increase the glue concentration, reduce the amount of glue, extend the aging time, reduce the hot pressing temperature or reduce the unit pressure of the hot pressing.

4. The reason for the indentation of the Combi Core Film Faced Plywood board: the backing board shows unevenness, the surface of the backing board is stuck with glue or debris, and the veneer fragments or debris are sandwiched between the layers of the board.
Solution: check and replace the backing plate, check the backing plate, clean it up, and pay attention to it when matching embryos.

5. Reasons for the warpage of Combi Core Film Faced Plywood: The structure and processing technology of the plywood do not conform to the principle of symmetry, the moisture content of the veneer is uneven, and the temperature and pressure are too high.
Solution: Pay attention to the principle of symmetry, improve the drying quality of the veneer, and appropriately reduce the temperature and pressure.

6. Combi Core Film Faced Plywood thickness is not uniform or the reason is beyond the allowable tolerance range: the number of hot-pressed sheets in each interval is too large, the thickness of the veneer is different, the pressure plate is inclined or the plunger is inclined, and the thickness of the plywood blank is not calculated Correct or the pressure in the hot pressing process is too high and the temperature is too high.
Solution: Use the hot pressing process of one pressing one by one as much as possible to improve the quality of the veneer, adjust the press installation to a level, adjust the thickness of the blanks, and adjust the pressure and temperature.
