Performance of Reconstituted Birch Veneer Lumber Impregnated with Melamine-Formaldehyde Resin
To improve the performance of veneer-based panel products,melamine-formaldehyde resin was impregnated into each individual Birch veneer by roller-pressing before lamination.The effects of resin content,compression rate of the roller-pressing,and pressure during hot-pressing were evaluated for selected panel properties including thickness swell,modulus of rupture,tensile strength,and internal bond strength.The results showed that with 50% resin content,20% compression ratio,and 2.0 MPa pressure during hot pressing to make the reconstituted veneer lumber,performance of the lumber could meet the desirable specifications.
