Abstract
The invention provides an improvement method of a solid wood board and belongs to the technical field of wood processing. The improvement method of the solid wood board comprises the following steps: manufacturing a blank, curing under high temperature and high pressure, drying, carbonizing and polishing the wood board. Through the improvement method of the solid wood board, the wood board is firstly cured under high temperature and high pressure and is subsequently dried and carbonized, so that the defects of surface cracks, internal cracks, end cracks and bending deformation of the board blank can be effectively avoided; meanwhile, due to the low carbonizing temperature, the phenomenon of surface discoloration can be effectively avoided; the board blank is placed in a metal frame and is compacted; the pressurization treatment is carried out in the carbonizing process; the phenomena of surface cracks, internal cracks and end cracks can be effectively avoided; the board blank is further cured under high temperature and high pressure and is subjected to two-stage treatment, so that the board blank is further treated more uniformly, and the quality of the board is further ensured.
Description
Technical field
The invention belongs to wood processing technique field, particularly relate to the improvement side of a kind of solid wood board
Method.
Background technology
Solid wood board is exactly the wood plank using complete timber (log) to make, solid wood board sheet material
Sturdy and durable, lines nature, mostly has the distinctive fragrance of natural timber, has preferably suction
Moist and breathability, is of value to health, does not cause environmental pollution, be make top-grade furniture,
The high-quality sheet material of decorating house.The process technology of traditional solid sawn plate, if entered with fresh timber
Row processing, its sheet material easily occur table split, implosion, end check and diastrophic defect, so
Traditional process technology needs timber is placed more than some months so that timber percentage of water loss reaches one
After determining degree, then according to becoming sheet material；But split owing to timber also there will be table in placement process,
Implosion, the situation of end check, and the water content of timber cannot accurately control, and causes part sheet material
Also there will be drawbacks described above.
Summary of the invention
For solving above-mentioned technical problem, the invention provides the modification method of a kind of solid wood board, tool
Body scheme is:
The modification method of a kind of solid wood board, comprises the following steps:
(1) stock makes: select fresh timber, by it according to becoming sheet material stock；And by plate
Material stock is positioned in metal frame, and surrounding is compacted；
(2) High Temperature High Pressure ripening is with dry: first carries out High Temperature High Pressure ripening, carries out
It is dried；
(3) carbonization treatment；
(4) sheet material polishing: being taken out by sheet material stock, then surface polishes smooth.
Further, described carbonization treatment step is: the metal frame equipped with sheet material stock is put into
In carbonization kiln, pressurize according to 1～2t/m2 in its top, and close the gate of carbonizing kiln and enter,
Air vent；Then temperature being increased to 80～100 DEG C, keep 4～6h, indoor humidity controls
20～30%；Then with the ramp of 0.4～0.7 DEG C/min to 140～155 DEG C, 2～4h are kept,
Indoor humidity controls 15～20%；Then the speed of 0.4～0.7 DEG C/min is lowered the temperature 80～100 DEG C,
Keeping 1～3h, indoor humidity controls 6～10%；It is cooled to room temperature in carbonization kiln.
Further, described High Temperature High Pressure ripening and drying steps particularly as follows:
(1) High Temperature High Pressure ripening: the metal frame that will be equipped with sheet material stock is positioned in vaporium,
Airtight steam heats, and pressure is 6～8 atmospheric pressure, and indoor temperature is 150～170 DEG C, during process
Between be 1～4h；
(2) it is dried: the metal that will be equipped with sheet material stock is frameed shift in placement hothouse, will be dried
The temperature of room controls at 60～80 DEG C, and pressure is 5～6 atmospheric pressure, and the process time is 2～4h.
Further, described High Temperature High Pressure ripening and be dried in High Temperature High Pressure ripening scandal at the beginning of
Level and two grades of High Temperature High Pressure ripenings；It is dried and is divided into primary and secondary drying, concretely comprise the following steps:
(1) primary High Temperature High Pressure ripening: the metal frame that will be equipped with sheet material stock is positioned over steam
Indoor, airtight steam heats, and pressure is 6～8 atmospheric pressure, and indoor temperature is 150～170 DEG C,
The process time is 1～4h；
(2) primary dry: the metal that will be equipped with sheet material stock is frameed shift in placement hothouse, will
The temperature of hothouse controls at 60～80 DEG C, and pressure is 5～6 atmospheric pressure, and the process time is 2～4h；
(3) two grades of High Temperature High Pressure ripenings: the metal frame that will be equipped with sheet material stock is positioned over steam
Indoor, airtight steam heats, and pressure is 3～5 atmospheric pressure, and indoor temperature is 130～150 DEG C,
The process time is 1～2h；
(4) secondary drying: the metal that will be equipped with sheet material stock is frameed shift in placement hothouse, will
The temperature of hothouse controls at 60～80 DEG C, and pressure is 3～4 atmospheric pressure, and the process time is 2～4h.
The beneficial effects of the present invention is: sheet material is first carried out at High Temperature High Pressure ripening by the present invention
Reason, be dried rear carbonization treatment, it is possible to be prevented effectively from sheet material stock occur table split, implosion,
End check and diastrophic defect；The most relatively low carburizing temperature can be prevented effectively from surface discolouration
Phenomenon；Place sheet material stock by metal frame and be compacted, carbonisation carries out pressurized treatments,
Can be prevented effectively from table split, implosion, end check phenomenon；Further High Temperature High Pressure ripening carries out two
Level processes, it is possible to further such that sheet material stock processes more uniform, be further ensured that sheet material matter
Amount.
