Abstract
Disclosed herein is a method for efficiently producing formaldehyde-free veneer manufactured boards, comprising steps of: using wood or non-wood veneer as a raw material; controlling the moisture content of the veneer to within an appropriate range; first applying an accelerant and then applying an isocyanate adhesive; then assembling the veneer into a slab according to a certain rule; carrying out microwave preheating on the slab; and feeding the slab into a hot pressing mechanism to obtain aldehyde-free veneer manufactured boards. In the present method, the process for producing aldehyde-free veneer manufactured boards is simple and easy to implement, hot-pressing production efficiency is high, and the mechanical properties of the boards are excellent.
