Problems solved by technology

[0005] The object of the present invention is to provide a whole sheet of bamboo recombined bamboo products for the existing common recombined bamboo products due to the existence of uneven density distribution and poor dimensional stability, which lead to the defects that are greatly restricted in the manufacture of high-end architectural decoration and outdoor products. Blank and bamboo composite material manufacturing method, develop a new bamboo composite material with uniform density distribution, good dimensional stability, and high transverse bonding strength

Embodiment 1

[0026] (1) Cutting: Select moso bamboo with a diameter of 80-90 mm, and cut the moso bamboo into a bamboo tube with a length of 1 m with a bamboo sawing machine.

[0027] (2) Sectioning: Use a bamboo cutting machine to divide the bamboo tube into 12 equal pieces of bamboo.

[0028] (3) Green removal: use a bamboo slicer to remove the green bamboo on the surface of the bamboo slices.

[0029] (4) Assembling, sawing grooves and pressing lines: arrange the bamboo slices 2 on the workbench, align the two ends of the bamboo slices 2 during the arrangement, and the total width of the bamboo slices after the arrangement is 500mm; compress the bamboo slices At both ends of the layer, adopt a cross saw to saw a saw groove 1 at the two ends of the bamboo slice 2 respectively, the width of the saw groove 1 is 2 mm, the depth of the saw groove 1 is 1 / 2 of the thickness of the bamboo slice 2, and the center of the saw groove 1 reaches The distance between the ends of the bamboo slices 2 i...

Embodiment 2

[0039] (1) Cutting: choose moso bamboo with a diameter of 110-120 mm, and cut the moso bamboo into a bamboo tube with a length of 2 m with a bamboo sawing machine.

[0040] (2) Sectioning: Use a bamboo cutting machine to divide the bamboo tube into 14 equal pieces of bamboo.

[0041] (3) Green removal: use a bamboo slicer to remove the green bamboo on the surface of the bamboo slices.

[0042] (4) Assembling, sawing groove 1 and crimping: the bamboo slices 2 are assembled on the workbench, and the two ends of the bamboo slices 2 are aligned during the arrangement. At both ends of the sheet layer, a saw groove 1 is respectively sawed at the two ends of the bamboo slice 2 by a scribe saw. The width of the saw groove 1 is 2mm, and the depth of the saw groove 1 is 2 / 3 of the thickness of the bamboo slice 2. The distance to the ends of the bamboo slices 2 is 150mm, and the hemp rope with a diameter of 3mm is pressed into the saw groove 1 to form a bamboo slice curtain.

Abstract

The invention discloses a method for manufacturing a bamboo wood whole-piece assembly and bamboo composite material. A whole-piece laminated bamboo bunch and flat-sawn cork veneer serve as the main raw materials, water-proof phenolic resins serve as auxiliary materials, and an outdoor bamboo composite material with high size stability can be produced under the hot-press condition. The method comprises the following steps: carrying out rip sawing and bamboo green removal on the bamboo wood before lamination processing; carrying out whole-piece processing on a bamboo chip; then, laminating the bamboo chip into a bamboo bunch curtain with wide breadth and loose structure; and when the bamboo composite material is assembled, causing the impregnated bamboo bunch curtain with wide breadth and the impregnated cork veneer to be mutually assembled. The bamboo composite material manufactured with the method has the advantages of high bamboo wood use ratio, even distribution of the internal density of the plate blank, good size stability and excellent longitudinal and lateral strength and can be used as high-grade building templates, furniture plates and indoor and outdoor decoration materials.

Description

technical field [0001] The invention relates to a method for forming a whole bamboo blank and a bamboo composite material, and belongs to the technical field of wood-based panel manufacturing in the wood industry. Background technique [0002] my country's bamboo forest area, stock volume, and bamboo industry output value all rank first in the world, and are known as the "Kingdom of Bamboo". According to statistics, my country's existing bamboo forest area is about 7.2 million hm 2 , of which Moso bamboo accounts for about 70%. Compared with wood, bamboo has the characteristics of high strength, good toughness, high hardness, elegant and beautiful texture, etc. It is an ideal raw material for manufacturing engineering structures and home decoration materials. [0003] Since the 1980s, my country has started the industrial application and research of bamboo resources, and has successively developed a series of products such as bamboo flooring, bamboo furniture, bamboo build...
