Problems solved by technology

However, because rubber wood contains about 8% starch and other polysaccharides and proteins, compared with other plantation woods, it is easy to rot, mildew, and insects. Although it has been carbonized, the anti-corrosion performance has been improved, but the termite-proof performance of the wood has not improved. Tests have shown that rubber wood is more susceptible to termites after carbonization, and its boards are used for furniture or interior decoration, and there are serious termite hazards in southern my country and other regions.

Embodiment 1

[0023] 1. The small rubber wood logs with a diameter of 6cm or more are sawn into specifications with multiple saws. The thickness specifications are 2.5cm, the width is 7.5cm, 6.5cm, 5.5cm, 4.5cm, and the length is more than 30cm;

[0024] 2. Put the rubber wood specification material stack into a vacuum treatment tank, and use 2.5% sodium octaborate aqueous solution as the treatment liquid for vacuum pressure infusion (for insect and termite treatment);

[0025] 3. The stacks of rubber wood specifications are air-dried and dried to a moisture content of 12% in a conventional manner, then discharged from the kiln;

[0026] 4. Put the specification material into the carbonization processing equipment, first quickly raise the temperature to 100°C, dry at high temperature for 3 hours, then raise the temperature to 130°C within 6 hours and dry for 2 hours, and then heat up to 185°C in 6 hours, and pass the steam intermittently during the carbonization process , Keep the wet bulb tempera...

Embodiment 2

[0029] 1. The small logs of rubber wood with a diameter of more than 6cm are sawn into specifications with multiple saws. The thickness specifications are 1.8cm, the width is 7.5cm, 6.5cm, 5.5cm, 4.5cm, and the length is more than 30cm;

[0030] 2. Put the rubber wood specification material stack into a vacuum treatment tank, and use 1.5% boric acid and 2.0% sodium tetraborate aqueous solution as the treatment liquid to vacuum and pressurize and impregnate it to prevent insects and termites;

[0031] 3. The stacks of rubber wood specifications are air-dried, and dried to 15% moisture content in a conventional manner, and then discharged from the kiln;

[0032] 4. Put the specification material into the carbonization treatment equipment, first quickly raise the temperature to 100°C, dry at a high temperature for 2 hours, then heat up to 130°C within 5 hours and dry for 1.5 hours, then heat up to 200°C within 7 hours and carbonize for 1 hour, stop heating , And then continue to pass in...

Embodiment 3

[0036] The carbonization temperature is 170°C, the length of the tenon is 12cm, and the other steps are the same as in Example 1.

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 [0001] The invention belongs to the technical field of wood processing, and relates to a production method of laminated timber, in particular to a production method of indoor carbonized rubber wood laminated timber. Background technique [0002] Glulam is an engineering material product manufactured from short wood materials into specifications, sizes and shapes that meet the requirements. It uses small-diameter materials as raw materials to cut round logs into plates, which are dried, cut, selected, and pointed. A series of processes such as splicing, splicing and subsequent processing are made into wood with a certain width, thickness and length. It is a new type of substrate used in the construction industry, furniture, and decoration industries. It retains the texture of natural wood and has high strength. (1.5 times that of natural solid wood), good fire resistance, high heat preservation performance, uniform moisture content, small deformation, etc., can ach...
