Problems solved by technology

Specifically, the carbonization heat treatment improves the texture and luster of the veneer of the fast-growing wood, making the texture of the veneer of the fast-growing wood appear full in color, and at the same time solves the problem that the existing veneer is prone to deformation and cracking of tiles, and solves the problem that the veneer of the fast-growing wood is prone to mold, blue, and decay. , affect the subsequent processing of veneer and the quality of the products obtained by subsequent processing, and improve the dimensional stability of veneer, especially fast-growing wood veneer, corrosion resistance and weather resistance, prolong the service life of veneer, and open up veneer after carbonization heat treatment The pit conduit greatly improves the permeability of the veneer; but at the same time, the carbonization heat treatment also reduces the surface hardness of the veneer, especially the fast-growing wood veneer, making the wood, especially the fast-growing wood, easier to burn

Embodiment 1

[0037] (1) Manufacturing steps of the veneer: select the masson pine sawn timber, and cut it into 5.5mm thick masson pine veneer by a frame saw.

[0038] (2) The first stacking and drying step: stack 4 pieces of masson pine veneer with a thickness of 5.5mm to form a stack, use trays with uniform specifications and aluminum alloy spacers, and the distance between the spacers and the end surface of the veneer is within 5cm when stacking , the distance between the bars is 20cm, and the bars are neatly formed into a straight line in the straight direction. Cement blocks are pressed on the stacked veneer, and placed in an air-drying shed for air-drying first (the average temperature of day and night is 25.3 ° C, the average temperature of day and night The wind speed is 2.1m / s, the season is September), and when the moisture content of the veneer is reduced to about 25%, it is then moved to a drying kiln for kiln drying, so that the moisture content of the veneer is ≤14%. The combi...

Embodiment 2

[0049] (1) Production steps of veneer: select poplar sawn timber, and saw it into 2.2mm thick poplar veneer by multi-blade sawing machine.

[0050] (2) The first stacking and drying step: stack 8 pieces of poplar veneer with a thickness of 2.2mm together to form a whole stack, use trays with uniform specifications and aluminum alloy spacers, and when stacking, the distance between the spacers and the end face of the veneer is 5cm Within, the distance between the spacers is 10cm, and the spacers are neatly formed into a straight line in the straight direction. Cement blocks are pressed on the stacked veneer piles, and the poplar veneer is dried by kiln drying technology to make the moisture content of the poplar veneer down to 14%.

[0051] (3) Carbonization heat treatment step: Send the dried veneer pile directly into the heat treatment kiln with a forklift, close the heat treatment kiln door, open the heating and humidification valves at the same time, heat up the veneer rapi...

Embodiment 3

[0060] (1) The veneer production step: select the radiata pine sawn timber, and make 3.6mm thick radiata pine veneer by sawing.

[0061] (2) The first stacking and drying step: stack 5 pieces of radiata pine veneer with a thickness of 3.6mm to form a whole stack, use pallets with uniform specifications and aluminum alloy spacers, and the distance between the spacers and the end face of the veneer is 5cm when stacking Within 10cm, the distance between the spacers is 10cm, and the spacers are neatly formed into a straight line in the vertical direction. Cement blocks are pressed on the stacked veneer, and the radiata pine veneer is dried by kiln drying technology to make the moisture content of the radiata pine veneer down to 14%.

[0062] (3) Carbonization heat treatment step: send the dried veneer pile directly into the heat treatment kiln with a forklift, close the heat treatment kiln door, open the heating and humidification valves at the same time, heat up the veneer quickl...

Abstract

The invention relates to wood functional improvement methods, in particular to a fast-growing wood flame-retardant reinforced wood veneer which is improved through the processes of wood charring heat treatment and flame-retardant reinforcement treatment, and a method for producing the same, belonging to the technical field of wood functional improving and wood processing. The method for producing the fast-growing wood flame-retardant reinforced wood veneer comprises the following steps of: (1) wood veneer manufacturing; (2) first-time superposing and drying; (3) charring heat treatment; (4) flame-retardant reinforcement treatment; and (5) second-time superposing and drying. The advantages of the charring heat treatment and the flame-retardant reinforcement treatment are gathered, and the defects of the charring heat treatment and the flame-retardant reinforcement treatment are overcome, so that the fast-growing wood flame-retardant reinforced wood veneer which is obtained through processing has the advantages of high dimensional stability, strong corrosion resistance and weather resistance, even penetration for flame retardant, good flame-retardant effect, high surface hardness, full color and luster for appearance of grains, simple production equipment and high out-turn percentage; and meanwhile, the defects that the traditional wood veneer is easy to be subjected to tile deformation and cracking, and the fast-growing wood veneer is easy to be subjected to mildewing, blue stain and rotting are overcome.

Description

technical field [0001] The invention relates to a wood functional improvement method, in particular to a fast-growing wood flame-retardant reinforced veneer improved by wood carbonization heat treatment and flame-retardant enhanced treatment processes and a production method thereof, belonging to the technical fields of wood functional improvement and wood processing. Background technique [0002] Generally speaking, the veneer is a thin plate with a thickness of 2 to 5 mm obtained by splitting the dried sawn timber through a frame saw, band saw or multi-blade saw. The veneer is usually used as solid wood composite flooring and solid wood furniture. Materials for surface decoration. Existing common veneers are precious hard broad-leaved materials, and the utilization of precious hard broad-leaved materials is not conducive to environmental protection and sustainable development of forestry industry. Moreover, because the veneer, especially the veneer of fast-growing wood, h...
