Description
Technical field
The present invention relates to a kind of method that wood composite board is produced using camphor tree residue, belongs to Wood-based Panel Production neck
Domain, refer specifically to utilize camphor tree residue（Diameter grade 3-10cm）Wood material is done instead of common wood raw material production wood-based plate method.
Background technology
Camphor tree is the multipurpose tree species for integrating timber-used, medicinal, spices, oil use and improvement of the ecological environment etc..Branck of Lignum cinnamomi camphorae,
Rich in natural borneol and linalool etc. be medicinal and spices native chemical composition in leaf essential oil, therefore, the camphor tree such as Jiangxi Province originates in
Ground uses coppice-method mode large scale cultivating medicinal and spices raw material forestbase.But branch and leaf after extraction of essential oil etc. utilize thing
Do not utilized efficiently also, at present mainly as extraction of essential oil when yule logs.
Timber mainly is broken into fiber for the processing method of the low diameter grade timber of traditional camphor tree and wood shavings location mode produces
This method of wooden boards, the method are present the original natural wood materials fiber destruction of camphor tree, and it is wooden original to reduce camphor tree
Physical property the problems such as, and need to mass produce, investment is huge, big to log resource consumption, and manufacturing procedure is complicated, uses
Work is more.It is not suitable for the present situation demand of current camphor tree industry processing.Timber be broken into fiber and wood shavings and meanwhile also exist lose it is excellent
The unfavorable factor such as matter surface texture and unique fragrance smell, remaining camphor tree branch after this technology is processed with camphor tree trimming or essential oil
Wood（Diameter grade 3-10cm）For main study subject, by the test to its basic mechanical properties, strengthen with plate property
Modification technology, the flattening laminating unit form improved technology that wood composite industrialization utilizes, filters out and is suitable for camphorwood residue
Veneer manufacture, the complete set technology and technological parameter of Wood composite manufacture, are obtained using loose veneer as main Component units
Low diameter grade camphorwood wood composite board process mating control technology, improves the comprehensive utilization ratio of camphorwood resource, and reach high level
The purpose utilized.
The content of the invention
Proposed by the present invention is a kind of method that wood composite board is produced using camphor tree residue, and its purpose is intended to
Utilize remaining available camphor tree trunk and branch wood raw material after camphorwood trimming or essential oil processing（Diameter grade 3-10cm）
Produce wood composite board sheet material.
Technical scheme：Using the method for camphor tree residue production wood composite board, comprise the following steps：
1）Camphor tree trunk and branch；
2）Trunk rotary-cut rolls；
3）Drying room is dried；
4）Gum dipping process；
5）Dried after glue；
6）Extravagant assembly；
7）It is compressing.
Advantages of the present invention：
（1）The camphorwood raw material diameter that this method uses is smaller, and more, source is wider, belongs to and being given up always in camphorwood
The material abandon, to leave unused, therefore substantially increase the utilization ratio of camphor tree discarded object；
（2）Veneer after this method rolls flattening changes the element form of raw material, and relieving should inside juggle
Power, the surface roughness of juggle is added, enhance the adhesion between slab and adhesive, make the camphorwood sheet material knot of preparation
Structure is relatively reliable, and density controllability is strong；
（3）Simultaneously compared with prior art operation break-down is by with the method that material crushes, the loose wood after this technology is handled is single
Plate is easy to assembly of mating formation, and is more beneficial for large-scale production, saves energy consumption, improves production efficiency, reduce recruitment cost；
（4）The camphorwood timber intensity produced using this method is high, and cost is low, and lines is attractive in appearance, and it is remaining to solve a large amount of camphorwoods
The problem of thing wastes；
（5）Camphorwood segment stress release after being flattened is complete, and internal bond is strong after assembly, and plate inner structure is reasonable, work
Skill improves the MOR and modulus of elasticity of sheet material, improves the nail-holding ability of plate face；Drying, glue mixing, assembly technique of mating formation, work
Sequence is simple, greatly improves low diameter grade camphorwood utilization ratio and labor productivity, reduces production cost, product is had very strong city
Field competitiveness；
（6）Camphorwood sheet material has unique aromatic odor in itself, not only can be mothproof with insect prevention, can also give consumer's body and mind
Pleasurable sensation is brought, there is the advantage incomparable with other biological material residue processing sheet material, product main application point
Cloth is in multipurpose application fields such as Furniture manufacture, construction and decoration, indoor and outdoor floor covering layers.
