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...
