Problems solved by technology

Although the existing wood carbonization treatment methods are various, and the performance of the carbonized wood produced has been greatly improved, it still has certain defects, such as the incomplete carbonization treatment of the wood surface in the existing carbonization treatment, which leads to the use of During the process, it will still be attacked by microorganisms, and its surface hardness and wear resistance will decrease after carbonization, which will affect its performance. Therefore, it is necessary to improve the carbonization treatment process.

Embodiment 1

[0026] A carbonization treatment method for wooden boards, comprising the steps of:

[0027] (1) Plate cleaning:

[0028] Classify and cut the boards to be processed according to the design requirements, and then rinse and clean the processed boards with clean water to remove the sand, dirt, wood chips and other impurities on the surface, and finally drain the surface water for later use;

[0029] (2) Surface modification treatment:

[0030] Put the board processed in step (1) into the closed furnace, put it in a graded code according to the size, then spray the atomized water vapor on the surface of the board, and at the same time raise the pressure in the closed furnace to 3.5MPa for joint treatment After 25 minutes, lower the temperature and lower the pressure in the closed furnace, and take out the plate for later use;

[0031] (3) Soaking treatment:

Abstract

The invention discloses a carbonization treatment method of a wood plate. The carbonization treatment method comprises the following steps of (1) plate cleaning, (2) surface modification treatment, (3) soaking treatment, (4) carbonization treatment, and (5) cooling treatment. According to the carbonization treatment method, the carbonization effect on the wood plate can be effectively improved, the thickness of a surface carbonization layer of the wood plate is effectively increased, the carbonization rate of a surface layer material of the wood plate is also well increased, meanwhile, reasonably-added nanometer silica enhances the density and mechanical property of the surface layer, the machining defective rate is obviously decreased, and good service value is achieved.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a carbonization treatment method for wood boards. Background technique [0002] Wood is one of the essential substances in people's life. In order to enhance the performance of wood, it is sometimes necessary to carbonize wood. After the wood is carbonized at high temperature, it not only makes the surface more beautiful, but also has the advantages of anti-corrosion, anti-biological attack, anti-deformation and cracking, and high temperature resistance. It also has the advantages of low moisture content, not easy to absorb water, stable material, and no deformation. , complete degreasing without grease, good heat insulation performance, no special smell and so on. Although the existing wood carbonization treatment methods are various, and the performance of the carbonized wood produced has been greatly improved, it still has certain defects, such as the inco...
