Problems solved by technology

The surface-enhanced wood obtained by this method takes a long time, has low production efficiency and high cost, and the wood is easy to burn under long-term high temperature, which affects the appearance of the wood.
In the above scheme of the prior art, in order to avoid the phenomenon of blasting and bubbling when using billets with high moisture content, it has to be overcome by prolonging the holding time after the compression process, but prolonging the holding time often greatly reduces the working efficiency
At the same time, the uneven distribution of moisture inside the compressed profile will easily cause deformation and cracking of the wood, which is not conducive to the development of industrialization

Embodiment 1

[0033] Select Daqing poplar as the test material, and saw the same specification of the plate according to the size of the press plate. The sawn boards are stacked, and the top of the pile is weighted. Use a forklift to put the stacked wood into a steam-heated top-wind drying kiln for drying and drying, and control its moisture content at 3%. Use a four-sided planer to polish both sides of the dried profile. The resulting polished surface is parallel to the fiber direction of the wood. Put the resulting polished log with a thickness of 25 mm into a three-layer hot press. Adjust the temperature of the press platen to 180 ° C. The pressing speed of the pressing plates is 3mm / s. When the upper and lower pressing plates are just in contact with the wood surface, the heat is kept for 400s, and the wood is heated and softened. After softening, close the press and compress the wood in the hot press to 19mm. The pressure of the hot press is 10MPa (equivalent to 103.32kg / cm 2 ), press...

Embodiment 2

[0037] Select Poplar tomentosa wood, and saw the board with the same specification according to the size of the press board. The sawn boards are stacked, and the top of the pile is weighted, and the stacked wood is dried and dried in a steam-heated top-wind drying kiln with a forklift, and the moisture content is controlled at 2%. Use a four-sided planer to polish both sides of the dried profile. The resulting polished surface is parallel to the fiber direction of the wood. Put the obtained polished log with a thickness of 27mm into a three-layer hot press. Adjust the temperature of the press platen to 190°C. The pressing speed of the pressing plates is 3mm / s. When the upper and lower pressing plates are just in contact with the surface of the log, the heat is kept for 350s, and the wood is heated and softened. After softening, close the press and compress the wood in the hot press to 19mm. When pressing, the pressure of the hot press is 12MPa (equivalent to 123.984kg / cm 2 ),...

Embodiment 3

[0041] Select paulownia wood, and perform sawing of the same specification on the board according to the size of the press board. The sawn boards are stacked, and the top of the pile is weighted. Use a forklift to put the stacked wood into a steam-heated top-wind drying kiln for drying and drying, and control its moisture content at 3%. Use a four-sided planer to polish both sides of the dried profile. The resulting polished surface is parallel to the fiber direction of the wood. Put the polished log with a thickness of 25mm into a three-layer hot press. Adjust the temperature of the press platen to 190°C. The pressing speed of the pressing plates is 3mm / s. When the upper and lower pressing plates are just in contact with the wood surface, the heat is kept for 450s, and the wood is heated and softened. After softening, close the press and compress the wood in the hot press to 19mm. When pressing, the pressure of the hot press is 8MPa (equivalent to 82.656kg / cm 2 ), keep the p...

Abstract

The invention belongs to the technical field of wood function improvement and wood processing, and specifically discloses an integral reinforced solid wood profile and a manufacturing method thereof. The method comprises the following steps: under the condition of low moisture content (1-3%), the wood is subjected to integral compression treatment with low compression rate by adopting a heating and softening forming technology, so as to obtain an integral compressed material with uniform cross-sectional density. The method can effectively reduce the phenomenon of blasting and bubbling caused by excessive steam pressure inside the wood, greatly shorten the heat preservation time, and improve work efficiency. The overall compressed timber profile obtained by the method of the invention has good dimensional stability, is environmentally friendly and healthy, and can be used for manufacturing solid wood floors, solid wood furniture and as interior decoration materials.

Description

technical field [0001] The invention belongs to the technical field of wood functional improvement and wood processing, and in particular relates to an integral reinforced solid wood profile and a manufacturing method thereof. Background technique [0002] Wood, steel bars, and cement have become the three basic raw materials of construction. Wood is running through all aspects of human life with its irreplaceable functions. Wood has become the preferred material in furniture and decoration materials due to its easy processing, high strength-to-weight ratio, good thermal insulation and electrical insulation, and natural and beautiful texture, luster and color. However, my country is a country seriously lacking in forests. In recent years, with the introduction of protection measures for natural forests that limit logging and ban logging, timber resources are becoming increasingly tense, and the contradiction between supply and demand of timber continues to aggravate. For th...
