Plywood is made of three or more layers of one millimeter thick single board or thin sheet adhesive heat.
Is currently hand-made furniture is the most commonly used materials, then plywood hot pressure when the solution of which?
1, if the water content of the single plate is too high or dry uneven, then the water content of the single plate should be controlled in the range of 8 to 12%.
2, if the amount of glue is too large, then should control the amount of glue in line with the process requirements.
3, if the pressure reduction speed is too fast or the hot pressure temperature is too high, then the second stage of buck should be slow, the heat pressure temperature should be appropriately reduced.
4, if the degree of resin shrinkage is not enough, then should check the quality of the resin.
5, if the hot pressure time is insufficient, then should be appropriate to extend the hot pressure time.
6, if the quality of the glue is poor, then should check the quality of the glue.
7, if the amount of glue is insufficient or uneven, then should pay attention to the amount of glue is moderate and uniform.
8, if the pressure is insufficient, or the temperature is too low, or the hot pressure time is too short, then the pressure should be appropriately increased temperature, or extend the heat pressure time.
9, if it is a single plate burr groove is too deep, the screw cutting quality is poor, then should improve the quality of the single-plate spin cut.
10, if the water content of a single plate is too high, then the water content of the single plate should be controlled not to exceed the prescribed range. 11, if it is too long aging time, glue has dried or aging time is too short, glue did not form a continuous film, then should mainly control the aging time, not too long and not too short
