Description
Technical Field
The utility model relates to a whole bamboo does not have crackle and expandes bamboo supporting ornamental material field, especially relates to kinds of whole bamboo does not have crackle and expandes dull and stereotyped bamboo wood composite sheet with the stuff complex of bamboo.
Background
China is the world mainly producing bamboo, and the area of the bamboo forest is about 400 kilohm2It accounts for more than 90% of the world's moso bamboo yield. The area of the bamboo forest in China is about 0.5 percent of the area of the national soil, about 2.9 percent of the area of the forest in China, and about five hundred million moso bamboos can be cut every year, which is equivalent to 1000 ten thousand meters3The bamboo forest resources of China are mainly distributed in 14 provinces, cities and hilly mountain areas in the south of the yellow river and the Yangtze river, and the resources are inexhaustible important biological resources as long as scientific management is carried out.
The moso bamboo is kinds of fast growing, high yield, high quality, easy to renew and restore important forest resources, it not only has short growth cycle, but also has superior physical and mechanical properties, but compared with wood, the characteristics of small diameter, thin and hollow wall and large sharpening degree bring many problems and difficulties for processing and utilizing the bamboo wood.
1. Most of the wood processing equipment and technology can not be directly applied in the bamboo processing, so the technical level of the bamboo processing industry is far behind the wood processing industry.
2. Due to the special structure of the bamboo wood, most products processed by the bamboo wood can only realize mechanical production, the individual working procedures or products are difficult to get rid of manual labor, and more difficulties in realizing continuity and automation exist, so the labor production efficiency of the bamboo wood processing industry is low.
3. The bamboo green on the outer surface and the bamboo yellow on the inner surface of the bamboo are not wetted by the adhesive, the material properties of the bamboo in the middle layer are greatly different, and the material which can be really used in the processing of the bamboo is the middle part, so the utilization rate of the bamboo is low, and the utilization rate is mostly between 20% and 50% according to different products.
4. Bamboo is difficult to be processed into large-size plates or square timber for utilization like wood through simple processing; the bamboo can only be processed into bamboo chips with the width of 20-30mm and the thickness of 5-8mm by sawing, cutting or planing, and is difficult to be directly utilized.
For the four reasons, the products made by simply sawing, cutting or planing the bamboo materials are expected to replace wood materials and surpass wood materials in the field of , and the success of the products in the aspects of performance, economy and the like is difficult to achieve, so that the main way of selecting and searching the industrial utilization of the bamboo materials becomes the main focus and breakthrough of the development of the bamboo material processing industry.
In recent years, people turn attention to the realization of crack-free unfolding of whole bamboos, if moso bamboos can be unfolded into crack-free bamboo flat plates, crack-free unfolded bamboo flat plates superior to high-quality timbers can be obtained, the crack-free unfolded bamboo flat plates can be directly used as decorative materials, and can also be compounded with other base materials to be made into bamboo-wood composite plates to replace wood plates, and an applicant matches the whole bamboo crack-free unfolded bamboo flat plates with battens and designs kinds of bamboo-wood composite plates in which the whole bamboo crack-free unfolded bamboo flat plates are matched with the battens.
SUMMERY OF THE UTILITY MODEL
