Embodiment Construction

[0027] Referring to the accompanying drawings, describe the manufacturing method of using waste wood to produce recombined composite boards:

[0028] (1) Preparation of the core plate,

[0029] ① Material type of core plate

[0030] Recycled waste wood has a variety of species. Before processing, it must be classified according to tree species. Different tree species or tree species with dissimilar properties cannot be mixed in the same core board. The material selection is easy to process, and the core strip is easy to flatten. Tree species with small shrinkage and deformation are processed and reorganized.

[0031] ②Requirements for core plate

[0032] The thickness of the control core plate accounts for 60-80% of the total thickness of the recombined composite plate, and the thickness should be consistent. For core strips assembled into core boards, it is usually more appropriate to use wooden strips with a thickness-to-width ratio of 1:1.5~2, and the thickness tolerance...

Abstract

The invention discloses a method for producing a recombinant composite board by using waste wood. The method comprises the following steps of: (1) preparation of a core board, (2) veneer finishing, (3) board blank gluing, blank matching and pre-pressing, (4) hot pressing, (5) trimming and sanding, and (6) inspection, grading and repair. The method has the advantages that: the square board of certain specification is manufactured by making full use of the waste wood, the core layer is spliced by using glue, two layers of veneers are covered on two sides of the core layer respectively, the recombinant composite board with five-layer structure is manufactured by hot pressing, and the reclaimed waste wood is used for substituting solid wood, so the material channel is broadened; low carbon, environment friendliness, greenness and resource property of the recombinant composite board are highlighted; the comprehensive utilization rate of the waste wood is improved, and the additional value and the technological content of the waste wood product are increased; and high use of small material, preferential use of poor material, fine use of coarse material and elaborate use of weak materialare realized in the waste wood.

Description

technical field [0001] The invention relates to a method for producing recombined composite boards by using waste wood, and belongs to the technical field of composite board production. Background technique [0002] Recycling waste wood to make boards and squares of certain specifications, and recombining composite boards to replace solid wood has not yet been reported. Contents of the invention [0003] The present invention proposes a manufacturing method for producing recombined composite boards by using waste wood. The board is made into a five-layer structure board by hot pressing, which replaces solid wood and broadens the use of materials. [0004] Technical solution of the present invention: it is characterized in that the method comprises the following process steps, [0005] (1) Preparation of the core plate, [0006] 1) Selection of core board material species, recycled waste wood, classified according to tree species, different tree species or tree speci...
