Embodiment 2a

[0042] Example 2a. Drying step: Poplar logs obtained by the timber method are: 1250×140×37mm, adopt air-drying and kiln-drying combined drying method, adopt air-drying drying (23.3° C. day and night average temperature, 2.7 day and night average wind speed m / s, the season is October), and when the moisture content of the wood is about 25%, it is moved to the drying kiln for drying according to the production process in Table 3, and the moisture content of the dried billet is about 12%. Table 3 Combined drying process of poplar wood air drying and kiln drying

[0043] b. Carbonization treatment: put the dried poplar wood directly into the wood carbonization equipment, heat up and humidify rapidly, the temperature rises to 80°C, and the humidity is humidified to 70% relative humidity, keep for 2 hours, and then adopt a stepwise heating method Raise the temperature to 125°C at a rate of 10°C / h and keep it for 2 hours, then use a stepwise heating method, increase the temperature...

Embodiment 4

[0060] Embodiment 4: a. Drying step: Paulownia logs are processed to obtain a plate with a thickness of 26 mm, and the moisture content of the wood is reduced to 12% by conventional drying methods in a conventional kiln, and then moved to a carbonization kiln.

[0061]b. Carbonization treatment: Close the carbonization kiln door and quickly heat up and humidify. The temperature is raised to 85°C, and the humidity is humidified to 75% relative humidity. ℃ and keep it for 3 hours, and then use the stepwise heating method to increase the temperature from 11 ℃ / h to 175 ℃, and keep it at the highest temperature for 2 hours. At 120°C, stop the kiln to complete carbonization, and leave the kiln immediately when the temperature naturally cools down to 50°C.

[0062] c. Restoration of moisture content: move the carbonized paulownia after leaving the kiln to the balance room, control the dry bulb temperature at 55°C and the temperature bulb humidity at 53°C for 4 days, so that the moist...

Abstract

The invention relates to a fast-growing wood surface reinforcing manufacturing method and sections manufactured thereby, belonging to the field of functional improvement on wood and wood processing. The technical scheme comprises the following steps of (1) drying step: drying fast-growing wood till a moisture content of 5-12%; (2) carbonizing step: carbonizing the fast-growing wood; (3) surface reinforcing step: compacting and reinforcing the surface of the fast-growing wood; and (4) thermally processing and fixing step: thermally processing and fixing the fast-growing wood at the temperature of 180-220 DEG C. The problems are solved that in the conventional technical scheme, the production process is complicated, the production cost is high, the wood yield is low, obtained sections are poor in texture and color and luster and poor in product stability, and the like; compared with the prior art, the fast-growing wood surface reinforcing manufacturing method has the advantages of simple process, no addition of any chemical in the production process, environment-friendly production, high production efficiency, capability of realizing large-scale flow-line production, low wood loss, high wood yield, low production cost and the like; and the obtained fast-growing wood surface-reinforced sections have the advantages of hard surfaces and soft middle parts or bottoms, high size stability, high corrosion resistance, clear texture, plump color and luster, good decorative effect and the like.

Description

technical field [0001] The invention relates to functional improvement of wood and its profile, in particular to a method for manufacturing fast-growing wood surface enhancement and its profile, and belongs to the technical fields of functional improvement of wood and wood processing. Background technique [0002] With the depletion of natural forest resources and the implementation of the national natural forest protection project, artificial fast-growing and high-yield forest timber will become the main way to alleviate the contradiction between my country's timber supply and demand in the future. Artificial fast-growing and high-yield forest timber mainly includes fir, masson pine, larch, poplar, paulownia and other tree species. Low hardness, non-corrosion and weather resistance, easy deformation and cracking and other defects limit its application range. Generally, it can only be used in the production of low-value-added semi-finished products such as plywood, particleb...
