Embodiment 1
[0027] Poplar is used as raw material;
[0028] Cut the poplar into veneers with a thickness of 0.5mm and a length of 2000mm by a rotary slicer, place them in an industrial cooking pot, add water and then add an appropriate amount of hydrogen peroxide to make the concentration of hydrogen peroxide in the cooking pot reach 2%, and cook for 45 minutes;
[0029] When the water temperature is controlled to 60°C, take out the veneer and place it in the sun to reduce the moisture content of the veneer to 8%;
[0030] Put the veneer in the dipping basket, hang it into the dipping pool, the dipping pool is filled with water-soluble phenolic resin adhesive, the solid content of the adhesive is 20%, the veneer is immersed in the water-soluble phenolic resin adhesive for 3 minutes, and then Hanging above the drain pool for 45 minutes;
[0031] Put the drained veneer on the drying tunnel truck and send it to the drying tunnel for drying. The temperature of the drying tunnel is controlled...
Embodiment 2
[0036] Using paulownia tree as raw material;
[0037] Cut the paulownia tree into veneers with a thickness of 2mm and a length of 800mm by a planer, place it in an industrial cooking pot, add water and then add an appropriate amount of hydrogen peroxide to make the concentration of hydrogen peroxide in the cooking pot reach 1%, and cook for 50 minutes;
[0038] When the water temperature is controlled to 60°C, take it out and place it in a carbonization furnace for 3 hours of high-temperature and high-pressure carbonization treatment, so that the color of the veneers reaches dark brown. Put these veneers on the drying tunnel and send them to the drying tunnel for drying. The temperature of the drying tunnel is controlled at 75°C to reduce the moisture content of the veneer to 9%;
[0039] Put the veneer in the dipping basket, hang it into the dipping pool, the dipping pool is filled with water-soluble phenolic resin adhesive, the solid content of the adhesive is 17%, the venee...
Embodiment 3
[0045] Use fast-growing wood as the raw material of wood-based panel corner waste as raw material;
[0046] Place waste wood-based panels in an industrial cooking pot, add water to cook for 30 minutes, pour out the waste water, add water and add a little coloring agent to soak for 1 hour, so that the color of the veneer is red;
[0047] Take out the veneer and place it in the sun to reduce the moisture content of the veneer to 6%;
[0048] Put the veneer in the dipping basket, hang it into the dipping pool, the dipping pool is filled with water-soluble phenolic resin adhesive, the solid content of the adhesive is 19%, the veneer is immersed in the water-soluble phenolic resin adhesive for 5 minutes, and then Hanging above the drain pool for 60 minutes;
[0049] Put the drained veneer on the drying tunnel truck and send it to the drying tunnel for drying. The temperature of the drying tunnel is controlled at 70°C to reduce the moisture content of the veneer to 10%;
