Embodiment 1

[0035] a. Manufacturing steps of veneer and base material: Saw the hard broad-leaved oak wood into a 2.2mm thick veneer, and saw the fast-growing masson pine into a 17.5mm thick base material.

[0036] b. Drying step: stack 5 pieces of oak veneer with a thickness of 2.2 mm together to form a stack, use pallets with uniform specifications and aluminum alloy spacers, and the distance between the spacers and the end face of oak veneer during stacking is within 5cm, and the distance between the spacers The spacing is 20cm, and the spacers are neatly formed into a straight line in the straight direction. Cement blocks are pressed on the stacked oak veneer, and placed in an air-drying shed for air-drying first (the average day-night temperature is 25.3°C, and the day-night average wind speed 2.1m / s, the season is September), and when the moisture content of the oak veneer is reduced to about 25%, it is then moved to a drying kiln for kiln drying, so that the moisture content of the v...

Embodiment 2

[0047] a. Manufacturing steps of veneer and substrate: Saw the hard broad-leaved ash ash to make a 3.6mm thick veneer, and saw the fast-growing sylvestris sylvestris pine to make a 12.8mm thick substrate.

[0048] b. Drying step: stack 2 pieces of 3.6mm thick ash veneer together to form a stack, use trays with uniform specifications and aluminum alloy spacers, and when stacking, the distance between the spacers and the end face of the ash veneer is within 5cm. The distance between the strips is 20cm, and the strips are neatly formed into a straight line in the straight direction. Cement blocks are pressed on the stacked mandshurica veneer, and placed in a drying kiln to dry, so that the moisture content of the veneer is ≤15%. According to the same drying procedure, stack 3 pieces of 12.8mm thick sylvestris pine base materials 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...

Embodiment 3

[0054] a. Manufacturing steps of veneer and base material: Saw the hard broad-leaved maple wood into a veneer with a thickness of 2.8 mm, and saw the fast-growing poplar wood into a base material with a thickness of 13.4 mm.

[0055] b. Drying step: stack 4 pieces of maple veneer with a thickness of 2.8mm together to form a stack, using trays with uniform specifications and aluminum alloy spacers. The spacing is 20cm, and the spacers are neatly formed into a straight line in the vertical direction. Cement blocks are pressed on the stacked maple veneer, and placed in a drying kiln to dry, so that the moisture content of the veneer is ≤15%. According to the same drying procedure, three pieces of 13.4mm thick poplar wood substrates are stacked together to form a whole stack, using trays with uniform specifications and aluminum alloy spacers. 10-20cm, the spacers are neatly arranged in a straight line in the vertical direction, and cement blocks are pressed on the stacked poplar b...

Abstract

The invention relates to wood functional improvement methods, in particular to a stable type double-layer ground-heating solid wood floorboard and a method for manufacturing the same, belonging to the technical field of solid wood floorboard processing. The invention has the technical scheme that the method comprises the following steps of: (1) wood veneer and substrate manufacturing; (2) drying; (3) charring heat treatment; (4) water ratio callback; and (5) veneering and fixing. Compared with the prior art, the technical scheme provided by the invention ahs the advantages of simple production process, short production cycle, low energy consumption, low production cost, high out-turn percentage and the like. The manufactured double-layer ground-heating solid wood floorboard has the advantages of better dimensional stability, more comfortable foot feeling because of hard surface and soft bottom, capability of being applied to ground heating and longer service life. In addition, the problem that the traditional wood veneer is easy to be subjected to tile deformation and cracking is solved, and a new technique for wood charring heat treatment is further provided.

Description

technical field [0001] The invention relates to a method for improving wood functionality, in particular to a stable double-layer floor heating solid wood floor and a manufacturing method thereof, belonging to the technical field of solid wood floor processing. Background technique [0002] Commonly referred to as veneer is a thin plate with a thickness of 2 to 5mm obtained by splitting dried sawn timber through a frame saw, band saw or multi-blade saw, called veneer, and veneer is usually used as a material for solid wood composite flooring. The veneer obtained after sawing dried boards has a high equilibrium moisture content and is easily affected by changes in ambient temperature and humidity, which can easily lead to deformation of its tiles. Some tiles have large deformations or even cracks, or small deformations are used for the production of solid wood composites. When the floor is forced to restore, a large part of it cracks, and even if it is made into a solid wood ...
