Description
Technical field
The invention belongs to woodwork production field field, more particularly to a kind of method of carbonization of wood processing.
Background technology
It is well known that carbonized wood can be divided into superficial charring and deep charring by degree of carbonization.Superficial charring is to use oxygen welding
Rifle carries out baking, wood surface is generated one layer of very thin charring layer, and the change to wood performance can not only be equal to wood oil,
The wood grain of concave-convex surface can also be highlighted, band gives people the aesthetic of vision.Application aspect concentrates on the side such as handicraft, finishing material
Face.Deep charring is also referred to as charing completely, homogeneity charing, is the timber by high temperature carbonization technical finesse, due in high temperature bar
Its nutrition is destroyed under part, is made it have preferable antiseptic insect-repelling function, is equal to anticorrosive wood, because its water absorbing functional groups half are fine
Dimension element is recombinated, and product is had good physical property, deep charring wood is real Green Product, is had without any
Noxious material, not only increases the service life of timber, and will not be useless during use and after use in process of production
Material processing has any negative effect to human body, animal and environment, available for wallboard, outdoor flooring, kitchen finishing and furniture
Deng many-side.Because carbonization of wood handling process is still in conceptual phase, the lumber quality of existing process processing is unstable, easily production
The quality problems of the shape that changes and cracking.
The content of the invention
The purpose for doing invention is that there is provided a kind of method that carbonization of wood is handled in order to solve the deficiencies in the prior art so that
Timber stability after processing is high, is unlikely to deform and ftractures.
The technical solution adopted in the present invention is:A kind of method of carbonization of wood processing, the described method comprises the following steps:
Step 1: being warming up to 50-60 DEG C to the ambient temperature of lumber kiln with 2-3 DEG C/h programming rate, carry simultaneously
High ambient humidity is to 90-100%, heat and moisture preserving 2-3 hours;
Step 2: timber is sawn into wooden unit or the lumps of wood, select to insert preheated wood after the stacking of identical dimensions is good
In material dry kiln, the temperature and humidity in step one is persistently kept to release the vapor in kiln after 6-8 hours;
Step 3: the environment temperature temperature programming of regulation lumber kiln is incubated 24-48 hours to 80-110 DEG C;
Step 4: when measuring timber water content respectively with Wood moisture tester and reaching 3-5%, stopping step 3 and simultaneously releasing in kiln
Vapor, then temperature programming is to 120-125 DEG C, and humidity is to 10-12% in regulation kiln, while being passed through wind speed into kiln for 1-
3m/s wind-force;
Step 5: the timber in step 4 is sampled, saw is three layers from outside to inside, is measured respectively with Wood moisture tester aqueous
Amount;
Step 6: detection is when moisture content reaches the whole moisture content of requirement, terminate drying, the cooling of timber room temperature is removed wood
Material dry kiln;
Step 7: by the timber in step 6 according to from top to bottom, order stacking from left to right it is rearmounted enter the vacuum carbonization of wood
In tank, hermetically sealed can door is brought rapidly up to after 100-105 DEG C by room temperature, is incubated 5-7 hours;
Step 8: after the completion of step 7, vacuum carbonized tank is passed through inert gas after being vacuumized, then enter wood dry charring pot
The temperature programming of the low heating rate of row, when in-furnace temperature reaches 180-220 DEG C, is incubated some hours;
Step 9: after step 8 terminates, stopping heating, natural cooling when being cooled to room temperature, is beaten again after carbonization tank is recovered into normal pressure
Can opening door, removes timber, and charing terminates.
Temperature programming in further optimization, the step 3 is broadly divided into two stages:
A, 80-100 DEG C, heating rate are 8-10 DEG C/h, are incubated 10-12 hours;
B, 100-110 DEG C, heating rate are 11-15 DEG C/h, are incubated 24-28 hours;
Temperature programming in further optimization, the step 4 is broadly divided into three phases:
A, cold stage, 25-80 DEG C, heating rate is 4-5 DEG C/h, is incubated 1-3 hours;
B, hot stage, 80-125 DEG C, heating rate is 4-5 DEG C/h, is incubated 2-4 hours;

Each spacing distance between timber and timber adjacent up and down is 1- in further optimization, the step 7
2cm。
The heating rate of temperature is 30-40 DEG C/h in further optimization, the step 7.
Temperature programming in further optimization, the step 8 is broadly divided into following two stages:
1), the low-temperature treatment stage, temperature be 100-160 DEG C;
A, 100 DEG C, heating rate be 1-2 DEG C/h, be incubated 2 hours;
B, 120 DEG C, heating rate be 1-2 DEG C/h, be incubated 2 hours;

The vacuum that carbonization tank is vacuumized in further optimization, the step 8 is 0.06-0.08MPA.
Inert gas in further optimization, the step 8 is nitrogen or argon gas.
Beneficial effects of the present invention are broadly divided into six aspects:
First, the timber in step 2 is in an environment up to 90-100%, in order to the moisture not allowed temporarily in timber to
Air evaporation, uniformly brings up to temperature from top layer to center the value required on drying schedule.
2nd, the purpose of step 3 Program heating is the progress preliminarily dried in order to promote the Free water in timber to volatilize, and
In step 4 at releasing it is moist after evaporation vapor, be further continued for the purpose of fixed heating rate temperature programming be in order to
Hygroscopic water in desiccated wood.
3rd, the purpose of the water content of sampling layering measurement timber is in order that must ensure that each of timber is partly attained by
It is uniform to dry, improve good drying effect.
4th, the purpose of the temperature programming in step be in order to prevent timber because dry too fast, uneven drying, such as timber
Appearance moisture it is readily volatilized, the comparatively speaking more difficult volatilization of the moisture of timber core, so as to cause the inside and outside uneven drying of timber
Weighing apparatus, forms cracking and deforms, the use in influence production and living.
5th, the high-temperature heating purpose of step 8 is in order that the amorphous region drop of the hemicellulose and cellulose in timber
Hygroscopic hydroxyl quantity greatly reduces in solution, timber, while such as resin of the extract in timber, terpenoid, tannin, acid
Class inclusion etc. is largely volatilized.Thus the hygroscopicity of timber is greatly reduced, and dimensional stability and corrosion resistance are significantly improved, this
Inert protective gas is filled with stage, tank, prevents timber from meeting oxygen burning at high temperature.
6th, it must be cooled to during natural cooling, and timber is aoxidized at high temperature, and normal pressure opening could be replied after room temperature
Tank door, otherwise not only easily produces fire but also the intensity of timber can be damaged.
