Description
Technical field
The present invention relates to treating of wood field, more particularly to a kind of elm sofening treatment method.
Background technology
Elm is a kind of important furniture and handicraft raw material, and elm is a kind of material lacking plasticity, and elm is in processing
Generally require during for product first to carry out a series of sofening treatment, improve its plasticity, so that the machine-shaping with the later stage.Generally adopt
With sofening treatment method be that water boils, sprays the physical methods such as steaming or carry out sofening treatment with chemical liquids such as liquefied ammonia, liquid caustic soda, tradition
The problem of elm fiber generally existing intensity decreases crossed of disposal methods, and the time that softens is long, and resource loss is many.
Content of the invention
Above-mentioned in order to overcome the shortcomings of, the invention provides a kind of elm sofening treatment method.
The present invention is achieved through the following technical solutions：
A kind of elm sofening treatment method, comprises the following steps：
(1), that elm surface clean is clean, be then placed on relative air humidity to be 75%, temperature be reach in 38 DEG C of environment flat
After weighing apparatus, take out；Can the distance between adding molecular chain, be that subsequent processing steps are layed foundation such that it is able to lift elm further
The effect that wood softens；
(2), the elm that step (1) is processed is carried out surface uniform irradiation 15min using the ultraviolet that intensity is 4000 μ W/cm；
(3), after, the elm processing step (2) is put into and soaked 5 minutes in glycerine, take out immediately；
(4) mass concentration, adding container volume 1/3rd in closed container is 63% BAS, then by step
(3) elm handled well is placed on above boric acid, and BAS is heated, and heating-up temperature is less than 92 DEG C, after 15 minutes, stops
Only heat, after 3-3.5 hour, closed container is lowered the temperature, cooling minimum temperature is not less than 12 DEG C, takes out elm；By this
Process, a part of hemicellulose easily decomposes and is dissolved into liquid, the free hydroxyl group adsorption moisture on cellulose unformed area strand,
Moisture film in cellulose gap is thickened, intermolecular distance increases, attraction reduces, be easy to produce under external force relatively sliding
Move such that it is able to improve elm bating effect；
(5) in closed container, add the saturation ammoniacal liquor of container volume 1/3rd, the elm then step (4) handled well
It is placed on saturated ammonia side waterborne, saturation ammoniacal liquor is heated, heating-up temperature is less than 96 DEG C, after 25 minutes, stop heating, 4-6
After hour, closed container is lowered the temperature, cooling minimum temperature is not less than 16 DEG C, takes out elm；
(6), the elm that step (5) is handled well is processed 2 hours under the conditions of 50 DEG C, relative air humidity 45%, air-dry to containing
The water yield is 48-50%, by this step process, it is possible to increase elm soften stability, and can make shape after
Elm intensity is improved.
Further, the sodium chloride solution that in described step (1), salt solution is 0.18% for mass concentration.
Further, in described step (4), elm and BAS distance are not less than 18 centimetres.
Further, in described step (5), elm and saturation ammonia spirit distance are not less than 14 centimetres.
The invention has the beneficial effects as follows：Sofening treatment method of the present invention, can make elm obtain preferable bating effect, place
The reason time is few, and safe, and the elm plasticity after sofening treatment and processing stability project, and effectively ensure that elm
Serviceability, the elm workpiece strength after sizing averagely improves 56%, and structure is compacted, and solves common wood softening method band
The intensity decreases problem come and soak only with ammoniacal liquor and soften the time longer problem spending so that through present invention softening side
Elm after method process, the intensity after dryness finalization is high, good toughness, and structure is compacted, and is conducive to the Quality advance of bool, bending
When percent defective reduce 80% compared to common softening method, the elm after sofening treatment of the present invention can obtain less
Bending curvature radius, after the inventive method is processed, can be greatly enhanced hydrophobicity, anti-corrosive properties and the dimensionally stable of elm
Property, it is simultaneously available for strengthening humidity resistance, reduce their moisture absorption and deformation rate.
Specific embodiment
