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 function improving and machining of wood and particularly discloses an integral reinforced solid wood section bar and a manufacturing method thereof. The method comprises the steps of under the condition of lower water content (1-3%), adopting a single heating softening molding technology to perform low-compression rate integral compressing treatment on the wood to obtain an integral staypak with the section being uniform in density. According to the method, bursting and bubbling phenomena generated by overhigh steam pressure in the wood can be effectively reduced, the thermal insulation time can be greatly shortened, and the work efficiency is improved. The integral compression wood section bar generated by the method is good in size stability, environment-friendly and healthy, and can be used for manufacturing solid wood floors and solid wood furniture and as indoor 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...
