As one of the commonly used materials in furniture, plywood improves the utilization rate of wood and is an important way to save wood. The quality of the adhesive determines the strength of the adhesive in the plywood production process. Only sufficient adhesive strength can ensure the quality of plywood.
But in the use will find plywood transmissus phenomenon, what is the reason, how to avoid this phenomenon?
The origin of the occurrence is:
1, the quality of the single plate is too poor, the opposite crack is too large;
2, the glue is too thin or too large, the aging time is too short;
3, the temperature of the thermal pressure is too high or the pressure is too high.
Keys to processing:
1, improve the quality of the single plate, reduce the depth of the opposite fissure;
2, increase the concentration of glue, eliminate the amount of glue, extend the aging time; 3, low hot pressure temperature or low hot pressure of the unit pressure.
