Description
Technical field
The present invention relates to Wood-based Panel Production technical field, produce work particularly to a kind of solid wood multi-layer structural slab
Skill.
Background technology
In current climate change by global concern, conserve forests and become human consensus, and money can be adopted by the world
In the case that source is reduced day by day, timber and goods demand thereof are continuously increased by socio-economic development, fully profit
With artificial fast-growing Commercial Forests, Forest Cultivation and logging residue and production and construction, renovate during useless
The resource development wood-based plates such as the wood fibre abandoned, to substitute traditional solid wood products, to protection wildwood resource,
Improve the ecological environment, meet the demand to Wood products for the economic development simultaneously, there is irreplaceable effect.
In prior art, wood-based plate has many types, generally comprise density board, glued board, core-board,
Particieboard etc., wherein, density board be exactly by log remove the peel, be ground into wood chip through defibrator separation after, then
Through HTHP shaping, density is higher than general sheet material, but its less stable, make moist meeting deformed dilation,
Be not suitable for using when width is bigger, should not be at finishing scene, nail-holding ability is poor；Glued board be commonly called as clamping plate or
Much more relatively multi-layer sheet, be to use to be also the earliest at present with a kind of timber to obtain.General by three layers or multilayer one
The veneer of millimeters thick or thin plate sticker hot pressing form, and the three-ply board that we often say is exactly by three layers of veneer pressure
System, but its less stable, deformation possibility is relatively big, and this is consistent due to its core material
Sex differernce causes, and is not suitable for the position of unifaciality, such as cabinet door etc..Glued board is also had to produce
When need substantial amounts of manually, as current cost of labor goes up day by day, glued board can be washed in a pan by market eventually
Eliminate；Core-board is commonly called as lumber core, is to be formed by glue laminated Wood block floor in the middle of two panels veneer, its market price
Position is high, timber resources consumes relatively big when producing, and resistance to mechanical intensity is low.
Therefore, a kind of Wood-based Panel Production technique how is provided so that it is the production cost of wood-based plate can be reduced,
And it is big to make the wood-based plate produced by this production technology have intensity, nail-holding ability is strong, and anti-bending strength is good
Advantage, become those skilled in the art's important technological problems urgently to be resolved hurrily.
Content of the invention
In view of this, the invention provides a kind of solid wood multi-layer structural slab production technology, so that reach can
