Problems solved by technology

The existing wood carbonization technology mainly puts the wood into a large cylinder and then heats it at the bottom. This carbonization process can only carbonize the surface of the wood, but cannot carbonize the wood deeply, so that the wood can be used After a long time, it will expand or deform and crack

Embodiment Construction

[0017] The present invention will be further described below.

[0018] Concrete steps of the present invention are:

[0019] (1) Material selection: choose neutral density wood;

[0020] (2) Cutting: Cut the wood into a cuboid shape by a chainsaw machine;

[0021] (3) Drying: Put the cut wood into the dryer for drying;

[0022] (4) Carbonization: carbonize the dried wood;

[0023] The step of described carbonization is:

[0024] A. Burn the heat-conducting oil in the heating furnace to 350°C-600°C, and the heated heat-conducting oil continues to flow onto the hot pressing plate of the hot press, so that the surface temperature of the hot pressing plate reaches 350°C-600°C;

[0025] B. Discharge the dried wood on the hot pressing plate, and ensure that the thickness of the wood on the hot pressing plate is consistent when placing it;

[0026] C. After the wood is discharged, the hot pressing plate is used to compress the wood, the pressing pressure is 1.5-2.0Mpa, and the...

Abstract

The invention discloses a technique of wood deep carbonation. The carbonation steps include: A, conduction oil is heated in a heating furnace to 350-600 DEG C, the heated conduction oil continuously flows on a hot press board of a hot press machine, and the surface temperature of the hot press board reaches 350-600 DEG C; B, dried wood is arranged on the hot press board, and in arrangement, uniformity of the thickness of the wood arranged on the hot press board is ensured; C, after arranged, the wood is pressed tightly with the hot press board, and the press pressure is 1.5-2.0MPa; D, after the wood is pressed tightly with the hot press board for 20-25min, the pressure of the hot press machine is promoted to 2.5-3.0MPa; and E, carbonation is carried out continuously for 35-40min, the hot press board is moved away, the wood is taken out, and the carbonation process is finished. The technique of the wood deep carbonation has the advantages that the deep carbonation of the wood is achieved, so that occurrence of the situations of expansion or strain cracking of the wood in use is reduced.

Description

technical field [0001] The invention relates to a wood deep carbonization process, which belongs to the technical field of wood processing. Background technique [0002] Wood is mainly composed of cellulose and hemicellulose. Cellulose acts as a skeleton in the wood cell wall, and its chemical properties and supramolecular structure have an important impact on the strength of wood. The hydroxyl groups in cellulose and water molecules can also form hydrogen bonds, and the hydrogen bonds between the hydroxyl groups in different parts directly affect the moisture absorption and desorption process of wood. A large number of hydrogen bonds can improve the strength of wood, reduce hygroscopicity, reduce chemical reactivity, etc., and the hygroscopicity of cellulose directly affects the dimensional stability and strength of the limit. After the wood is carbonized, the concentration of hydroxyl groups is reduced, and the chemical structure undergoes complex changes, so that the hyg...
