Abstract
The invention relates to a production method for indoor integrated carbonized rubberwood, which includes: sawing rubberwood log into specified wood, and subjecting the specified wood to termite proofing treatment, stacking, air drying and carbonizing; and subjecting the carbonized specified wood to tenoning, finger jointing, polishing, paneling and sanding to obtain the indoor integrated carbonized rubberwood. By means of combination of high-temperature carbonization and termite proofing treatment, the strength, moth and termite resistance, durability and mould proofing performance of the integrated rubberwood can be effectively improved, the integrated carbonized rubberwood has the coffee appearance, has the advantages of low variation of equilibrium moisture content, stable size, high corrosion resistance and the like, and is widely applicable to indoor furniture, floors, stair boards, decoration, fitment and the like.
Description
Technical field
The invention belongs to the timber treatment technology field, relate to a kind of production method of integrated timber, specifically is a kind of production method of indoor charing rubber wood timber integrated timber.
Background technology
Integrated timber is to manufacture the specification that meets the requirements and a kind of engineering section product of shape as required by short and small timber; It is raw materials for production with the path material; Round log is cut into sheet material, through oven dry, fracture, select materials, series of processes such as finger, splicing and subsequent treatment and process have certain width, the timber of thickness, length, be a kind of novel base material that building trade, furniture, repairs profession are used; Kept the material sense of natural timber; Have intensity big (for 1.5 times of wood), fire protecting performance is good, heat-insulating property is high, moisture content is even, is out of shape characteristics such as less, can accomplish the big usefulness of small wood; The excellent usefulness of bad material plays facilitation to the protection of forest resourceies.
Rubber tree (Hevea brasiliensis) is extensively planted in China torrid zone and Southeast Asia, the important artificial forest merchantable timber of producing for the torrid zone.The rubber wood timber diffuse porous wood, drying shrinkage is little, is prone to processing.The integrated timber of tradition rubber wood timber production is mainly used in indoor furniture and finishing.
The carbonized wood of employing elevated temperature heat method of modifying production can improve the corrosion resistant performance of timber, can improve Wood Dimensional Stability again.And that the carbonized wood integrated timber has size is more stable, and stress is littler, is difficult for warpage, and the better characteristics of durability are (referring to CN 100500394C; CN 100500395C), enlarged the scope of application of integrated timber.But rubber wood timber is compared with other artificial forest wood because of containing polysaccharide and the protein such as starch up to about 8%, and is apt to rot, go mouldy, damage by worms; Though handle through charing, antiseptic property improves, and timber prevents the not improvement of termite performance; Test shows, for rubber wood timber, more subjects to the erosion of termite moth after the charing; After its sheet material was used for furniture or interior decoration, there was serious termite hidden danger in use in areas such as China south.
Summary of the invention
The production method that the objective of the invention is to be directed against the deficiency of prior art and a kind of indoor charing rubber wood timber integrated timber is provided; Earlier rubber wood timber is carried out insect protected and heat modification charing processing; Finger is produced the rubber wood timber integrated timber again; Outer appearnce is like the decorative effect of tropical hard wood such as teak, characteristics such as have that termite-proof moth erosion is effective, equilibrium moisture content changes little, dimensionally stable, corrosion resistant performance is good.
The technical scheme that the present invention adopted:
A kind of production method of indoor charing rubber wood timber integrated timber, its step is following:
1, the rubber wood timber log saw is separated be the specification material, its specification is respectively below the thickness 3.0cm, below the width 12cm, more than the length 5cm;
2, rubber wood timber specification stockpile buttress being inserted the application of vacuum jar, is that treatment fluid carries out vacuum pressure impregnating (carrying out the termite-proof processing of insect protected) with the boride aqueous solution;
3, will through the rubber wood timber specification stockpile of the termite-proof processing of insect protected buttress gas do to moisture content be 11%～13%, kiln discharge;
4, the rubber wood timber specification material after gas is done is inserted the charing treatment facility, is rapidly heated to 100 ℃ high temperature drying 2～10 hours earlier; Then in 1～10 hour, be warming up to 130 ℃ of dryings 0.5～6 hour, in 2～10 hours, be warmed up to 160 ℃～220 ℃ charings 0.5～6 hour then, carbonization process intermittently feeds steam and keeps 100 ℃ of wet-bulb temperature; Continue to feed the steam cooling damping then; Treat that specification material moisture content is 6%～8%, when temperature is no more than 30 ℃, draws off;
5, the specification material after the carbonization is used the briar fracture, thicknesser is scraped, and transversal rejecting defectiveness position (contain die for the sake of honour, the position of defective such as knot) is elected the 2-3 class as according to the aberration branch; Mortise, tenon gluing, finger, S4S; Lath side gluing, jigsaw was placed 12 hours; Repair sanding, warehouse-in.
Among the present invention, said rubber wood timber log is meant that diameter surpasses the rubber wood timber saw lumber log of 12cm at the rubber wood timber batten of 6cm～12cm or diameter.
Among the present invention, said boride is a kind of or its compound in boric acid, sodium tetraborate, eight Boratexes.
Among the present invention, behind vacuum pressure impregnating, the boron equivalent concentration in the rubber wood timber specification material timber is 0.2%～1.2%.
Among the present invention, refer to during mortise that tenon length is 7～15cm.
Among the present invention, it is white glue with vinyl that said finger sticks with glue agent, and room temperature is placed planing after 3～6 hours behind the finger.
Among the present invention, the adhesive for splicing boards stick is the mixture of white glue with vinyl and isocyanates (curing agent), and wherein the percentage composition of isocyanates is a content 5～15%, 20 ℃～60 ℃ of adhesive solidification temperature, 25～80 minutes hardening times.
Above-mentioned indoor charing rubber wood timber integrating timber production method; Also can timber be processed square bar, insect protected and dry back saw are processed behind the small dimension material charing and finger jigsaw again, or after timber processed square bar; After insect protected, drying, the charing again saw process finger jigsaw behind the small dimension material; Change to produce order, production efficiency is different, but the performance of the indoor charing rubber wood timber that does not change the present invention and produced.
The present invention adopts the pattern that high temperature carbonization is handled and termite-proof processing combines; Can improve the dimensional stability of integrated timber, anti-moth and termite moth erosion performance, endurance quality, fungicidal properties effectively; The charing rubber wood timber integrated timber of gained has coffee-like outward appearance; Have equilibrium moisture content and change characteristics such as little, dimensionally stable, corrosion resistant performance are good, can be widely used in indoor furniture, floor, staircase boards and decorations etc.
