Plywood is a type of building sheet that we often use, which is not cut from a piece of wood, but is made of thin wood that is bonded together with adhesive. With the progress of technology is also the strict requirements of plywood manufacturers, plywood service life has been extended, performance is also very stable.
If plywood has a low plycerate or degluing phenomenon, more reason is that the heat pressure production is not up to standard, let's understand the reason and solution.
Reason:
1, poor quality of glue;
2, the amount of glue is not enough or the glue is not evenly balanced;
3, aging time is too long, the glue has dried or aging time is too short, the glue did not form a link of the glue film;
4, the pressure is not enough, or the temperature is too low, or the heat pressure time is too short;
5, single plate burr groove scars too deep, twisting quality poor;
6, the water content of the single plate is too high.
Solution:
1, check the quality of the glue;
2, meticulous lying the amount of glue moderate and balanced;
3, important control aging time;
4, proper progress pressure containing temperature, or extend the thermal pressure time;
5, progress single board spin-cutting quality; 6, control single plate moisture content does not override the delineated category.
