Abstract

Wood is processed into wood bundles by normal art work, the wood bundles do not break transversely and are loose and interlacedly connected along the longitudinal direction, and the arrangement direction of prior fiber is kept. Bamboo wood can also be processed into bamboo bundles by normal art work. The wood bundles and the bamboo bundles are respectively dried and provided with glue, and then are organized by mixing between layers or within layers. After heating, wood-bamboo restructured products which are proper in denseness and have very good physical mechanics properties and processing properties are achieved. Wood-bamboo restructured products with different physical mechanics properties and processing properties can be achieved by adjusting the mixing mode and mixing ratio of the wood bundles and the bamboo bundles, which remarkably extends the application area and the application scale of the material.

Because the bamboo timber resource of China is very abundant, since Australia developed the wood of successfully recombinating, a lot of research units of China used for reference the manufacturing process and the principle of reorganization wood, and attempting development is the reorganization bamboo product of raw material with the bamboo wood.Since 1987, Nanjing Forestry University determines to utilize bamboo wood (the bamboo tip of a branch especially, tiny sundry bamboo) research direction of compacting reorganization bamboo, production technology to the reorganization bamboo has been carried out preliminary research, inquired into the bamboo wood softening process, discongest mode (roll-in and hammering), resin added and applying glue mode (impregnation and spray glue), the bamboo fiber bundle washing, glue kind and resin added, hot pressing temperature, hot pressing pressure and hot pressing time be to a series of problems such as reorganization bamboo Effect on Performance, and having suppressed with wild assorted bamboo in the laboratory is raw material, reorganization bamboo with higher MOR and elastic modelling quantity.Up to the present, the Chinese Academy Of Forestry Research Institute Of Wood Industry reorganization bamboo that also to have suppressed with wild assorted bamboo in the laboratory be raw material; Zhejiang Forestry Institute is also studied reorganization bamboo heat pressing process, manufactured experimently with thunder bamboo, Ph. bambusoides, show filal obedience bamboo and bambusa texlitis be raw material, remove blue or green and the recombined bamboo plate that does not go blue or green two types, and compared their performance.
The typical process flow of producing the reorganization bamboo is:
The reorganization bamboo has many advantages: the one, and the utilization rate of bamboo height, the reorganization bamboo can dwarf bamboo, bamboo inferior or bamboo processing leftover bits and pieces are raw material, and utilization rate of bamboo is up to more than 90%; The 2nd, physical and mechanical property is good, reorganization bamboo longitudinal strength height, and material is even, and length, density can be adjusted control as required, can be used as structural timber, furniture woods, floor etc.; The 3rd, processing characteristics is improved greatly, processing such as the reorganization bamboo can be sawed, plane, mortise, and nail-holding ability is higher, all need not pass through preliminary treatment before dyeing, sanding, covering with paint.Reorganization bamboo smooth surface, beautiful texture also can carry out secondary operations such as veneer, facing, and technology is simple and cost is lower.Therefore, the reorganization bamboo also is a kind of new product that development potentiality is arranged very much.
Reorganization wood and reorganization bamboo also respectively have their weak point.The reorganization bamboo has higher physical and mechanical property, but density is higher; Though reorganization wood machinability is better, intensity is lower.Therefore, limited this two classes application of novel material scope and application scale.
Three, summary of the invention
Purpose of design of the present utility model is, at reorganization wood and reorganization bamboo deficiency separately, makes that a kind of density is moderate, intensity is high, has the wooden bamboo recombined material product of fine processing characteristics again.
Technical solution of the present utility model is:
With timber routinely processes become laterally do not rupture, vertically loose and staggered continuous and keep the wood bundle of original fiber alignment direction; With bamboo material also processes well-thought-out plan bundle routinely.After wooden Shu Yuzhu bundle given drying, applying glue respectively, with the wood bundle and the bamboo bundle mixes with interlayer or layer in the mode assembly that mixes, after hot pressing, can obtain density moderate, have a wooden bamboo recombined material product of good physical and mechanical property and processing characteristics again.Adjust the hybrid mode and the mixed proportion of wood bundle and bamboo bundle, can obtain the wooden bamboo recombined material product of different physical and mechanical properties, expanded the range of application and the application scale of material greatly.
