The products of high-quality film faced plywood manufacturers are made of laminated veneers layer by layer. The veneers need to be dried after gluing to eliminate the large amount of moisture brought into the core board due to the gluing. Some dry Knowledge of skills and methods is still necessary.
In the production of film faced plywood, the main purpose of drying the veneer after coating is to reduce the content of volatiles and prevent defects such as penetration, bubbling and opening of the slab during hot pressing. The veneer coated with glue in the production of packaging boards is generally No drying. When drying, the initial moisture content of the veneer, the amount of glue applied, the type of adhesive, the temperature of the medium in the drying equipment, the wind speed and the relative humidity are the conditions that determine the drying process. Among them, temperature is the main condition, generally 70 to 80 degrees, not more than 90 degrees. This is a production information that should be focused on during board drying to ensure that the quality of the packaging board produced is good.
With the continuous improvement of the production technology of film faced plywood manufacturers, the veneer drying is done under the background of large mechanization, which not only improves the work efficiency but also ensures the quality, so that the quality of the packaging board produced is excellent and the application effect is better. .
