Embodiment 1
[0017] A method for manufacturing hard wood using high-frequency heating and curing, characterized in that the specific implementation steps are as follows:
[0018] The product specification implemented is: 2460×128×198mm, the blank specification is: 2500×130×200mm, the density of the product after pressing is 0.9, the raw material used is a kind of amorpha branch in the shrub, and the adhesive used is E 0 Grade urea-formaldehyde resin, its cured content is 50%,
[0019] (1) Decompression preparation of pressed materials: Amorpha fruticosa branches are rolled with a roller compactor, and the branches of Amorpha fruticosa are sent into the roller compactor in turn, and the round shape of Amorpha fruticosa is rolled The branch becomes a long and flat wooden thread, and its outer skin is separated from its main branch, and the long and flat wooden thread after peeling is used as a pressing material for subsequent use;
[0020] (2) Drying of standby materials: Drying the elongat...
Embodiment 2
[0026] A method for manufacturing hard wood using high-frequency heating and curing, characterized in that the specific implementation steps are as follows:
[0027] The implemented product specification is: 2460×128×198mm, the blank specification is: 2500×130×200mm, the density of the product after pressing is 1.1, the raw material used is poplar among fast-growing species, and the adhesive used is water-soluble phenolic resin. Its cured product content is 48%,
[0028] (1) Preparation of pressed materials: use a wood rotary cutter to cut the 2500mm long poplar raw material into a wood veneer with a thickness of 1mm, then cut the wood veneer into a 1mm wood strip with a wire cutter. Reserve as pressed material;
[0029] (2) Drying of spare materials: the elongated wood strips made of poplar wood should be dried before dipping. The drying equipment used is a mesh belt dryer. The temperature is 90°C, the wind speed is 5m / s, the mesh belt travel speed is 6m / min, the drying tim...
