Description
Technical field
The present invention relates to a kind of Wooden modifying processing method, more particularly to a kind of drying integrated place's science and engineering of wood preservation
Skill.
Background technology
Modern age wood preservation technology is as the development of chemical industry gets up, more than nearly 170 up to now
In the time in year, the species of timber preservative gradually increases, and corresponding wood preservation handling process also develops constantly.
The technology and present Research and development trend of comprehensive whole wood preservation, all the time around this core of environmental protection
The heart.The purpose for carrying out preservative treatment is to extend the life-span of woodwork, so as to save the forest reserves；During preservative treatment,
Be combineding with each other between active ingredient and timber principal component is only the most key technical problem in strengthening preservative.
The content of the invention
It is an object of the invention to overcome disadvantages mentioned above, there is provided a kind of drying integrated handling process of wood preservation, its
First timber is pre-processed before carrying out preservative treatment to timber, i.e., high-temperature process, and point three differences are carried out to timber
Temperature stage is processed so that timber had first carried out high temperature carbonization and activation process before preservative treatment is done so that wood
The hemicellulose containing hydrophilic radical-hydroxyl is reduced in material, and molecule interchain oxygen key combines the chemical compositions such as enhancing, cellulose drop
Solve and regroup, and several micropores are etched in wood surface, thus improve the dimensional stability of timber, corrosion resistance,
Anti-deformation.
In order to realize the purpose of the present invention, the technical solution adopted by the present invention is：
A kind of drying integrated handling process of wood preservation, its step is as follows：
A, timber cut off according to requirements, timber is placed in the container equipped with conduction oil, it is desirable to which conduction oil is covered
Timber；
B, point three temperature sections are heated up to conduction oil, and constant temperature 20-40min is controlled after conduction oil is warming up to 120-150 DEG C,
Constant temperature 15-25min is controlled after then proceeding to be warming up to 200-240 DEG C, constant temperature 30- is controlled after being then warming up to 250-280 DEG C
60min；
C, taking-up timber stand cooling 20-48h；
D, the timber after cooling is placed in the meshbeltfurnace of 6 length, be put into before timber first toward in stove and meanwhile be passed through inert gas with
Vapor, at 850-860 DEG C, guipure transmission control is in 1-3m/s for in-furnace temperature control；
E, treat that timber is cooled to less than 50 DEG C, timber be placed in the closed container with heating function, toward container in add it is anti-
Then rotten agent solution vacuumizes 20-30min and toward the pressure of applying 1.2MPa in closed container to timber is covered, and pressure is lasting
Time is 1-2h；Then release vacuum and extract antiseptic solution out, carry out vacuumizing 20- again after antiseptic solution is extracted out and finished
30min, then heats to closed container, the thermostatic control 1-2h after temperature in container is reached between 70-80 DEG C, detection wood
Material moisture content；
F, taking-up timber stand cooling.
Further, the antiseptic solution is the inorganic compound solution containing copper ion.
Further, the antiseptic solution is copper-bath.
First timber was pre-processed before preservative treatment is carried out to timber, i.e., high-temperature process is carried out to timber, and
Three different temperatures stages are divided to be processed.First stage high-temperature process causes timber using the characteristic of conduction oil and high temperature
In spun off containing a small amount of unstable oily matter, improve timber dimensional stability, reduce the timber later stage cracking and become
The probability of shape；Second stage high-temperature process causes timber deep charring, forces dividing for the chemical compositions such as the cellulose in timber
Subchain is recombinated, and strengthens the activity of lumber fibre strand, while the hemicellulose containing hydrophilic radical-hydroxyl is reduced, enhancing
The water-resistance and corrosion resistance of timber；Three phases high-temperature process causes that wood surface reacts with water vapour, in timber
Surface etch goes out multiple micropores, in order to adsorbing and retaining preservative, prevents being oxidized or disengaging for preservative.
In addition, carrying out vacuum drying treatment after present invention immersion preservative to timber, temperature control is 70-80 DEG C, dry
Curing process is carried out to the preservative in timber micropore while dry so that preservative is ion implanted timber depths, improve anti-
Conjugation between rotten ion and timber, prevents anti-corrosion ion from because being chronically exposed to oxidation or disengaging occurring in air, further
Improve antiseptic effect.
The advantage of the inventive method：PROCESS FOR TREATMENT is simple, easily operation, and treated timber has waterproof, fire-retardant, resistance to
The features such as burn into cracking resistance, termite-proof and good stability of the dimension.
