Problems solved by technology

However, in actual use, it is still found that the steps are too complicated, and precise detection and control processing are required at the same time, which increases the cost and the processing time is still long
In addition, this method has a relatively shallow effective carbonized layer for direct carbonization of wet wood, and the properties of the wood such as bending strength, impact toughness, and nail holding power are all reduced, which affects the use performance of the wood.

Embodiment 1

[0021] A fast and direct deep carbonization process for wood planks, comprising the following steps:

[0022] (1) Material selection: select wooden boards with neutral density and thickness greater than 1cm for use;

[0023] (2) Shaping: Cut the board into a regular cuboid shape with a cutting machine;

[0024] (3) Planing: planing the surface of the shaped board;

[0025] (4) Drying treatment: discharge the wood boards treated in step (3) on the hot-pressed plate to ensure that the temperature of the hot-pressed plate is the same as that of the cellar where it is located. When the moisture content of the wood board is MC > 55%, control the hot-pressed plate The pressing pressure on the board is 0.25Mpa, the temperature in the cellar is controlled at 53°C, and ultrasonic waves with a frequency of 33KHz are applied at the same time for synchronous processing until the moisture content of the board is not greater than 55%; when the moisture content of the board is 35% < MC≤ Wh...

Abstract

The invention discloses a rapid and direct board deep carbonization process. The rapid and direct board deep carbonization process includes the following steps of (1) material selection, (2) shaping, (3) wood shaving, (4) drying treatment, (5) insulation treatment, (6) carbonization treatment and (7) cooling treatment. All steps in the method are scientifically and reasonably matched, boards can be subject to carbonization operation directly, the energy loss is reduced, and meanwhile the overall carbonization treatment time length is shortened by about 30%; and the thickness of an effective carbonization layer of the board is increased by one to two times, the properties of crack resistance, bending resistance, impact toughness, the nail-holding ability and the like of the boards are better improved, and the using value is higher.

Description

technical field [0001] The invention belongs to the technical field of wood carbonization, and in particular relates to a fast and direct deep carbonization process of wood 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, anti-deformation and cracking, and high temperature resistance. It has the characteristics of low moisture content, not easy to absorb water, stable material, no deformation, completely degreased without overflowing, good heat insulation performance, and no special smell. It is an ideal furniture and indoor and outdoor decoration material. [0003] In the prior art, before carbonizing the wood board, it is necessary to carry out drying treatment to reduce the water content of the wood board below a certain level to pre...
