With the reduction of global natural hardwood resources and the increase of environmental protection pressure, natural hardwood has become more and more expensive. Most tropical species are protected by environmental protection laws and their use is prohibited, which hampers the development of China's timber industry

[0021] 1. The end of the fast-growing veneer such as eucalyptus (thickness 1.5-6.4mm) is obliquely ground and glued, and then continuously lengthened. The length of the length is determined according to the length of the finished bamboo grain wood. When cutting the length, it must be calculated According to the billet assembly plan, the length of the joint distance between the adjacent long veneers of each layer is controlled within a predetermined size range, so as to ensure that the joints of each adjacent veneer that are matched according to the billet structure are dislocated in the direction of the length of the veneer.
[0022] 2. Use the self-made strip cutting machine to cut and glue the lengthened veneers matched with the finished product. The width of the cut strips is 5-63mm. After the strips are glued, the veneer strips are bidirectionally arranged in the length and width directions to form blanks, and they are air-dried and shaped on a specially designed cooling pl...

Abstract
The invention discloses bamboo grain wood made of man-made forest raw materials and a manufacturing technology thereof and belongs to the field of wood machining. Bamboo grain wood is made of man-made forest fast-growing wood veneer, the environment protection idea of recycling resources and achieving sustainable utilization and development is realized, policy requirements for green building materials are met, the problem that at present, usage of decoration converted timber in China completely depends on importation after commercialized production can be solved partially, and guidance is provided for high-end oriented and high value-added utilization of man-made forest fast-growing wood in China. By the adoption of the layered slab sizing technology, ultra-thick building structural wood which is 51-133 mm thick can be formed quickly through hot press, and by the adoption of the bidirectional oriented veneer mat formation assembly technology (different from PSL), the defects of man-made forest veneer products that the number of dead knots is large and the number of cracking positions is large are overcome. In this way, a bamboo grain wood finished product is made to have the texture, grain, decoration property, machining property and mechanical property similar to those of natural solid wood, and the bamboo grain wood finished product can be used as wooded building structural wood and can also be used in non-structural wood fields such as furniture making.
Description
(1) Technical field [0001] The invention is a new technical invention in the field of plantation wood processing and utilization. (2) Background technology [0002] China is a large country of timber consumption, and timber resources are scarce. Although fast-growing eucalyptus, fast-growing poplar and other artificial forests have developed rapidly in recent years, and basically solved the problem of materials used in the production of Chinese wood-based panels (fiberboard, particleboard, plywood substrates), but wooden structures, floors, etc. , sawn timber for solid wood furniture and large-diameter logs all rely on imports. With the reduction of global natural hardwood resources and the increase of environmental protection pressure, natural hardwood has become more and more expensive. Most tropical species are protected by environmental protection laws and their use is prohibited, which hampers the development of China's timber industry. Bamboo-grain wood, the raw mater...
