According to the bamboo willow fiber board manufacturing technology, small-diameter grade materials and brush wood of bamboo willows can be made into the bamboo willow fiber boards, so that industrial production of bamboo willow artificial boards is realized, demands on raw materials of bamboo willow wood are improved, and wide plantation of bamboo willow is further promoted.
Description
Technical field
The present invention relates to a kind of bamboo willow fibre board manufacturing process, bamboo willow can be made fibre board.
Background technology
Gradually decrease the pay attention to day by day to ecological environmental protection with various countries with global wildwood resource, constantly increase
Timber demand and relative inadequacy of resources between contradiction more and more deeper, and make full use of small diameter grade material and brush wood then becomes slow
Solve one of important channel of this contradiction.
Bamboo willow be Salicaceae (salicaceae) sallow.Arbor, growth potential is big, highly up to more than 20m.Bark
When young, green, smooth.This kind is hybridization of willows kind, has very strong fast-growing character and adaptability.Bamboo willow is suitable for soil ph value
8.0～8.5, the heavy saline area of salinity 0.8%, and water logging remains to normal growth in two months, can extensively plant in lake beach
Painting, salt-soda soil.Bamboo willow is just new seeds of approved fast-growing in recent years, from the U.S., also known as U.S. bamboo willow, is trembled with fear by the U.S.
Willow, korean willow, osier willow, the improvement of Phyllostachys pubescens Mazei ex H.de Lebaie assortment of genes selection cross, the domestic choosing through nearly 4 years is preferably educated and is tamed, and makes bamboo willow
On the basis of inheriting traditional willow kind many merits, further increase the fast-growing character of this seeds, have than poplar more
The fast speed of growth.This kind is conducive to changing the single situation of China's quick growing species of trees, promotes fast-growing, high-yield woods to send out to diversification
Exhibition, it will bring broader development space to the development of China's forestry industry.
At present the research of bamboo willow is mainly with biomass energy characteristic, cold-resistant, Saline alkali tolerance and its in paper pulp papermaking
Application etc..However, bamboo willow is as a kind of fast growing wood kind, its application in timber industry does not also obtain deep grinding
Study carefully.
Content of the invention
The technical problem to be solved is: the problem overcoming prior art to exist, and provides a kind of bamboo willow fibre board
Bamboo willow successfully can be made the gratifying fibre board of performance by manufacturing process.
The technical scheme that the present invention solves its technical problem is as follows:
A kind of bamboo willow fibre board manufacturing process, comprises the following steps:
The first step, take the bamboo willow small diameter grade material meeting following conditions and brush wood as raw material: content of bark is mass ratio
10-25%；The age of tree is life at least 3 years；Microcephaly end with diameter greater than or be equal to 5cm；Average fiber length is more than or equal to
0.74mm, the average single wall of fiber is thick to be more than or equal to 3.60 μm；
Second step, taken for first step raw material is chipped or pulverizes, it is little that the length of gained wood chip is less than or equal to 30mm, width
In or be equal to 25mm；
3rd step, defibrator process after second step gained chip steaming is obtained fiber, fiber yield reaches mass ratio more than 84%；
4th step, by the 3rd step gained fiber drying to moisture content for mass ratio below 11%, applying glue stick；
5th step, assembly of mating formation, hot-press solidifying obtain bamboo willow fibre board.
The topmost key point of above-mentioned manufacturing process is: (1) must be little to meet the bamboo willow of all qualificationss of the first step
Footpath level material and brush wood are raw material；(2) wood plate size must be made to meet the restriction of second step.Research worker of the present invention is through in depth
Find after practical studies, in strict accordance with the restriction of above-mentioned manufacturing process, especially want emphasis to be controlled according to above key point,
The bamboo willow fibre board that performance meets national standard can be produced, national standard is gb/t 11718-2009 " medium density fibre board (MDF) ".
Manufacturing process of the present invention technical scheme perfect further is as follows:
Preferably, in the 3rd step, cooking pressure is 0.6-0.8mpa, and boiling temperature is 165 DEG C -170 DEG C.
So just can further ensure that bamboo willow piece is effectively softened, wear and tear in machines can not only be reduced moreover it is possible to make defibrator process institute
Obtain fiber more elongated.
Preferably, in the 5th step, after hot-pressing the phase adopt stagewise release, unload that pressure pressure is continuous, little by little decline.
So just can further ensure that the moisture discharged in slab, reduce fibre board moisture content and prevent layering drum
Bubble.
Preferably, the physical and mechanical property of the 5th step gained bamboo willow fibre board meets national standard gb/t 11718-2009
Regulation.
Preferably, in the 4th step, adhesive is urea-formaldehyde glue；Resin added is mass ratio 12-14%.
Preferably, in the 5th step, it is pressed on bamboo willow fibre board with object, and after placing at least 72 hours, then carry out the later stage
Process；Later stage processes and at least includes one of cutting edge, sanding, saw section.
Preferably, in the 5th step, bamboo willow fibre board is density in 0.65-0.80g/cm3Between medium density fibre board (MDF) or
Density is more than 0.80g/cm3High density fiberboard.
Additionally, the present invention also provides the bamboo willow fibre board being obtained using above-mentioned technique, the physical mechanics property of bamboo willow fibre board
The regulation of national standard gb/t 11718-2009 can be met.
Bamboo willow small diameter grade material and brush wood can be made bamboo willow fibre board by the present invention, thus for bamboo willow in wood-based panel industry
Promotion and application theory and practice foundation is provided, realize the industrialized production of bamboo willow wood-based plate, improve to bamboo willow material former material
The demand of material, and then promote the extensive plantation of bamboo willow, in short supply with promotion varieties in saline-alkali areas expanding economy all to alleviating timber resources
Have great importance.
