Embodiment 1

[0045] (1) Wood chip production steps: select the masson pine sawn timber, and cut it into 5.5mm thick masson pine wood chips by a frame saw.

[0046] (2) The first stacking and drying step: stack 5 pieces of masson pine wood chips 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 in a straight line in the vertical direction. Cement blocks are pressed on the stacked veneer, and placed in the air-drying shed for air-drying first (the average temperature of day and night is 25.3 ° C, day and night The average wind speed is 2.1m / s, the season is September), and when the moisture content of the wood chips 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 10%. The combined drying proce...

Embodiment 2

[0059] (1) Wood chip production steps: select poplar sawn timber, and saw it into 4.5mm thick poplar wood chips by a multi-blade sawing machine.

[0060] (2) The first stacking and drying step: stack 2 pieces of poplar wood chips with a thickness of 4.5mm together to form a whole stack, use trays with uniform specifications and aluminum alloy spacers, and the distance between the spacers and the end surface of the veneer is 5cm when stacking Within 10cm, the spacing of the spacers is 10cm, and the spacers are neatly formed in a straight line in the vertical direction. Cement blocks are pressed on the stacked wood chips, and the poplar wood chips are dried by a kiln drying process to make the poplar wood chips dry. rate was reduced to 15%.

[0061] (3) Heat treatment improvement step: Send the dried wood chip 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 wo...

Embodiment 3

[0070] (1) Steps for making wood chips: select poplar sawn timber, and slice it into 1.2mm thick poplar wood chips by a slicer.

[0071] (2) The first stacking and drying step: stack 5 pieces of 1.2mm thick poplar wood chips together to form a whole stack, use trays with uniform specifications and aluminum alloy spacers, and the distance between the spacers and the end surface of the veneer is 5cm when stacking Within 10cm, the spacing of the spacers is 10cm, and the spacers are neatly formed in a straight line in the vertical direction. Cement blocks are pressed on the stacked wood chips, and the poplar wood chips are dried by a kiln drying process to make the poplar wood chips dry. rate was reduced to 15%.

[0072] (3) Heat treatment improvement steps: Send the dried wood chip 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 wood veneer directly to 190°C fo...

Abstract

The invention relates to a method for improving wood functionality, in particular to a flame-retardant solid wood composite profile improved through wood heat treatment and flame-retardant treatment processes and a manufacturing method thereof, which belongs to the technical fields of wood functional improvement and wood processing. A method for manufacturing flame-retardant solid wood composite profiles, comprising the steps of: (1) wood chip production step; (2) first stacking and drying step; (3) heat treatment improvement step; (4) atmospheric-pressure impregnation flame-retardant treatment step for wood chips; (5) The second stacking drying step; (6) Gluing and fixing step. Combining the advantages of carbonized heat-treated wood and flame-retardant treated wood, and overcoming their respective shortcomings, the solid wood composite profiles obtained after treatment have high dimensional stability, strong corrosion resistance and weather resistance, good flame retardant effect evenly penetrated by flame retardants, and simple production equipment. The production cost is low, and the wood yield is high. The obtained solid wood composite profile is a good material for beams for indoor structures, furniture and flame-retardant wooden doors.

Description

technical field [0001] The invention relates to a method for improving wood function, in particular to a flame-retardant solid wood composite profile improved through wood heat treatment and flame-retardant treatment processes and a manufacturing method thereof, belonging to the technical fields of wood function improvement and wood processing. Background technique [0002] As a renewable resource, wood is more and more valued by people, but the anisotropy of wood itself makes wood prone to warping, cracking, deformation, perishability, mildew, and short service life during use, especially fast-growing wood. , these wood defects are more serious, thereby limiting the use of wood. Therefore, in order to improve the dimensional stability of wood and prolong the service life of wood, people have carried out many scientific research activities on the improvement of wood function. [0003] Chinese patent document CN1868704A discloses a technical patent of "a wood carbonization t...
