[Abstract] The present invention discloses a method for manufacturing a small-diameter wood-based panel, which comprises the following steps: (1) material preparation: pressing the yellow broom wood through a thorny roller with a roller pressure of 60-80 MPa to obtain a yellow broom wood bundle; (2) drying the yellow broom wood bundle to a moisture content of 8-10%, and then applying glue with a glue amount of 15-17%. The glue type is a mixed adhesive, wherein the mixed adhesive is prepared by mixing phenolic resin adhesive with polyisocyanate molecule adhesive in a ratio of m phenolic resin adhesive to m polyisocyanate molecule adhesive = 1-6:0.3. The adhesive is mixed with polyisocyanate molecular adhesive; (3) Assembly method: The yellow broom wood bundles are assembled in a cross-shaped principle; (4) Hot pressing: The assembled small-diameter wood artificial board blanks are hot pressed with a hot press, the hot pressing temperature is 140-160℃, the time is 1.1-1.3min/㎜, and the pressure is 2.0-3.0MPa; (5) Edge sawing process: The hot-pressed small-diameter wood artificial board is sawed and inspected with an edge saw according to the design requirements, and then put into storage.
[Sovereign Item] A method for manufacturing a small-diameter wood-based panel, characterized by comprising the following steps: (1) preparing the material: pressing the yellow broom wood through a thorny roller at a roller pressure of 60 MPa to 80 MPa to obtain a yellow broom wood bundle; (2) drying the yellow broom wood bundle to a mass moisture content of 8% to 10%, and then applying glue in an amount of 15% to 17% by mass, wherein the glue is a mixed adhesive, wherein the mixed adhesive is a mixture of phenolic resin adhesive and polyisocyanate molecular adhesive in a mass ratio of m phenolic resin adhesive to m polyisocyanate molecular adhesive = 1 to 6:0.3; (3) Assembly method: Lay multiple broom wood bundles flat to form a layer of broom wood bundle boards, and then assemble at least two layers of broom wood bundle boards according to the principle of cross-intersection between the upper layer of broom wood bundle boards and the lower layer of broom wood bundle boards; (4) Hot pressing: Use a hot press to hot press the assembled small-diameter wood artificial board blanks, with a hot pressing temperature of 140℃～160℃, a time of 1.1min/㎜～1.3min/㎜, and a pressure of 2.0MPa～3.0MPa; (5) Edge sawing process: Use an edge sawing machine to saw the edges of the hot-pressed small-diameter wood artificial boards according to the design requirements, inspect them, and then put them into storage.
