Problems solved by technology

Although carbonized wood has many advantages mentioned above, the crack resistance and bending resistance of wood after carbonization will generally decrease. For thicker boards, most of them are used for the support and load bearing of the main body. Performance is of great significance, and its crack resistance will also affect its use value. At present, there are few studies on the influence of deep carbonization of thicker plates on the plate, and there are few studies that focus on improving and enhancing its crack resistance and bending resistance.

Embodiment 1

[0028] A kind of deep carbonization method of heavy wooden plank, comprises the steps:

[0029] (1) Wood cutting:

[0030] Cut the wood board to be processed according to the requirements of the processing design, and then rinse the sawdust and other impurities with clean water for later use;

[0031] (2) Wood pre-drying treatment:

[0032] Put the wooden boards treated in step (1) into a drying kiln, and dry the water content to 18-20% for later use;

[0033] (3) Deep drying treatment:

[0034] 1) Continue to dry the wooden board after step (2), keep the temperature in the drying kiln at 105°C, increase the pressure in the drying kiln to 1MPa, and apply ultrasonic waves with a frequency of 53KHz to the wooden board , until the water content of the board is dry to 12~13%;

Abstract

The invention discloses a deep carbonation method for a thick and heavy wood plate and belongs to the technical field of wood processing. The method specifically comprises steps as follows: (1) cutting of the wood plate; (2) pre-drying treatment of the wood plate; (3) deep drying treatment; (4) carbonation treatment; (5) tempering treatment. All the steps of the method are reasonably matched, the cracking resistance and the bending resistance of the wood plate can be well improved, can be 8% and 5% lower than those of a conventional wood plate respectively and are about 40% and 20% lower than those of the wood plate treated with a traditional method, the method has the remarkable improving effect, meanwhile, the whole treatment duration of the technology is shortened by 30%-40%, the efficiency is higher, and the method has the high popularization value.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a deep carbonization method for heavy wooden boards. Background technique [0002] Carbonized wood refers to the wood obtained after homogeneous carbonization treatment of wood in a high temperature environment. In addition to the beautiful surface, the carbonized wood also has the advantages of anti-corrosion, anti-biological attack, high temperature resistance, and because of its moisture content Low weight, not easy to absorb water, stable material, no deformation, completely degreased and no grease, good heat insulation performance, no special smell, etc., it is an ideal furniture and indoor and outdoor decoration materials. [0003] The carbonization of wood can be divided into surface carbonization and deep carbonization. As the name implies, the depth of surface carbonization treatment is relatively shallow, which is generally used for thinner plates or...
