Urea formaldehyde dipping.The width at oblique angle 7 is 8-15cm.Extend 80-100mm on give up 3 oblique angle 7 of plate layer and four sides of sandwich and mat formation and there are wood shavings
6.Wood shavings 6 are mated formation between papery mold 5 and baffle 4.
The utility model also provides a kind of manufacturing method of thick core bamboo plywood of regeneration recombination, applied to above-mentioned regeneration weight
The thick core bamboo plywood of group, comprising the following steps: (1) sorting: it is with waste and old, discarded bamboo glue pattern plate, bamboo shaving plate or bamboo wood
Raw material simultaneously carries out preliminary screening and classification；(2) it pre-processes: sanding surface being carried out to the raw material chosen, removes surface blot, dust
And metallic foreign body etc., and remove four sides of the raw material breakage；(3) oblique angle 7 processes: carrying out oblique angle 7 to pretreated plate core
Processing；(4) bamboo curtain splint, bamboo mat are dry: bamboo curtain splint, bamboo mat is dry to moisture content 8-12%；(5) it is glued: phenolic resin is diluted to
12-18% adjusts resin added, bamboo mat resin added 23-30%, bamboo curtain splint resin added 12-15% according to dip time, and wood shavings are used and mixed
Glue mode, resin added 20-30%, displays drying for standby；(6) plate core is mated formation molding: baffle 4 being opened, is placed at chamfering
Papery mold 5, wood shavings 6 of mating formation, and carry out hot-forming；(7) plate core is glued: carrying out two-sided apply to plate core using glue spraying mode
Glue；(8) hot pressing recombining: bamboo mat is mated formation in bottom, successively mat formation bamboo curtain splint, plate core, bamboo curtain splint, bamboo mat, and is hot pressed into
Type, 150-180 DEG C of hot pressing temperature, pressure 2.5-3.0MPa, hot pressing time 20-30min；(9) it post-processes: saw side, chamfering, sand
Light, if product is integrally using optional reinforcing and Seal treatment.
Preliminary screening during sorting is specifically carried out by table 1 mainly for skin lamination, rotten and edge breakage etc.,
Then it is grouped according to the specification of raw material；Recombination processing, its processing is the edge of raw material is first carried out sawing, is gone
Remove, and oblique angle processing carried out to four sides, expose internal fresh face, then edge mat formation wood shavings 6 carry out it is hot-forming.
Wood shavings 6 are mated formation between papery mold 5 and baffle 4, and it is one that papery mold 5, which directly melts with the plate of raw material, after hot pressing
Body；Papery mold 5 selects disposable tool.
6 amount of mating formation of wood shavings is according to surface area and thickness at oblique angle 7, by design density 0.95-1.15g/cm3Mat formation,
Wood shavings 6 use phenolic resin, and 6 resin added of wood shavings is 20-30%；The useless sizing of plate layer 3 of bamboo mat layer 1, bamboo curtain splint layer 2 and sandwich was mated formation
Cheng Zhong, bamboo mat resin added 23-30%, bamboo curtain splint resin added 12-15%；Sizing uses glue spraying mode, resin added 2.2kg/m2, and
Hot-forming parameter therein is 150-180 DEG C of hot pressing temperature, pressure 2.5-3.0MPa, hot pressing time 20-30min, carries out heat
It is also needed behind pressure, saw side to thick core bamboo plywood progress chamfering and sanding surface again is recombinated, for the Regenerated plate integrally used
It may be selected to be fixed and close using fixed device.
The waste and old bamboo plywood specification and quality of recycling are irregular, recombinate thick core bamboo plywood quality to ensure to regenerate,
It first has to be selected, rejected and classified, the glued board that serious damage, layering or rotten degree are more than 20% occurs to surface and want
It rejects, then satisfactory waste and old bamboo board be grouped according to specification, sanding is carried out to surface layer, removes table
The spots such as face cement, dust.
The quality requirement of old glued board is specifically selected to be shown in Table 1
The requirement of 1 waste bamboo board quality of table
| Surface fracture | Edge breakage | It is rotten | It comes unglued on surface layer | Layering | Fracture | Bending deformation | |
| Quality requirement | Allow | Allow | ≤ the gross area 20% | Allow | ≤ the gross area 30% | Allow | Do not allow |
Waste and old laminboard layer directly will lead to four side quality with bamboo mat hot pressing and be difficult to control, and glued board book size also produces
It has given birth to " shrink ".In order to keep original book size and edge quality, in recombination process, first by the edge of old plate core
Sawing, removal are carried out, exposes internal fresh face, edge is mated formation the hot pressing again of wood shavings 6.
Discovery is recombinated using right-angle side in test preliminary examination, and regeneration recombinates wood shavings 6 and old plate core in thick core bamboo plywood
Junction mechanical strength it is lower, material transition is too obvious, it is easy to cause to be broken.In order to carry out slow transition, by old plate core
The chamfering of certain length is first processed on four sides, and 7 width of oblique angle is generally 8-15cm.
In order to increase the size of finished product and enhance old plate core and recombinate thick core bamboo plywood overall coherence, at oblique angle 7 and
Four sides extend 100mm and mat formation wood shavings 6.Mating formation for wood shavings 6 is technological difficulties at oblique angle 7, uses papery mold in the utility model
5, wood shavings 6 are mated formation wherein, papery mold 5 be it is disposable, directly combine together with plate.
Glue spraying mode is used to the sizing of old plate core, breadth is 85cm × 85cm × 25mm (length × width x thickness), and resin added is
Every plate 1.6kg, hot compression parameters are set as 160 DEG C, pressure 3MPa, hot pressing time 25min.
Regeneration in the utility model recombinates the manufacturing method of thick core bamboo plywood, and overall craft process can also carry out
Refinement, specially old bamboo clappers → screening → sanding surface → go four sides → 7 processing of oblique angle → be glued → display drying → plate core at
→ hot-forming → saw side → chamfering → sanding → closing that type → recombination thickness core rubber plywood mats formation, so as to keep regeneration recombination thick
The material resources mechanical property of core bamboo plywood reaches products standards requirement.
Performance test
According to JG/T 156-2004 " bamboo plywood form " or JG/T 428-2014 " steel framework combination bamboo plywood form "
Regulation tests plate, and is compared with conventional bamboo plywood form.Specifically it is shown in Table 2.
The new and old plate of table 2 is compared with performance
It should be noted that the regeneration in the utility model recombinates thick core bamboo plywood, as long as with the utility model
The basic principle of manufacturing method is identical, is only the simple additions and deletions or replacement of some step, also in the protection of the utility model
In range；In addition, the setting about series of parameters such as oblique angle, resin addeds in the utility model, is only in the utility model
The embodiment that may be implemented enumerated, in specifically manufacture production process, as long as being able to satisfy corresponding processing request and last
It can guarantee that the material resources mechanical property of the thick core bamboo plywood of regeneration recombination can also carry out exchange appropriate, also fall into the utility model
Protection scope in.
Specific case is applied in the utility model to be expounded the principles of the present invention and embodiment, it is above
The explanation of embodiment is merely used to help understand the method and its core concept of the utility model；Meanwhile for the one of this field
As technical staff, based on the idea of the present invention, there will be changes in the specific implementation manner and application range.To sum up
