In the plywood production process, many processes are required to ensure the quality of plywood. Among them, the drying process is essential, it will directly affect the production quality of plywood, determine the service life of plywood, so should be processed in accordance with the standard, and strict requirements.
Let's take a look at the drying of plywood. General lying after the plywood moisture content is very high, if directly applied to glue, because too much water will extend the hot pressure time, easy to produce bubbles, will also affect the glue, so that the production of plywood dry shrink stress is very large, easy to deform and crack; Therefore, the plywood after the spin cut must be dried in time.
The final moisture content of single-plate drying is most suitable and should be determined according to the required performance of the glue species, tree species and plywood used. If from the drying efficiency of the dryer and the single sheet yield consideration, the water content of the single plate will be more favorable, but from the glue quality consideration, the moisture content is higher, the glue quality is reduced; Therefore, determining the appropriate final water content is very important for the quality of the single plate.
