Problems solved by technology

[0005] ①Since the thickness of the veneer strips is usually within 0.5-3mm, there is almost no natural texture of the wood itself. After the veneer strips are laminated and hot-pressed into laminated lumber, there will usually only be lamination. Horizontal texture, and the distance between laminated textures changes only by the change of the opening angle, the shape of the texture is single, and the color is not clear
[0006] ②Because of the hot pressing process itself, pressure is only applied on the upper and lower sides of the raw material, and there are gaps arou

Embodiment 1

[0075] a, material selection, select low-age eucalyptus and cut it into a thickness between 0.5mm-3mm, width between 5mm-59mm, and dry the veneer strips to a moisture content below 12%; wherein low-age eucalyptus refers to Juvenile Eucalyptus; Typically, Juvenile Eucalyptus refers to Eucalyptus trees that are 2 to 8 years old.

[0076] b. Sizing, the solid content of the sizing is 9%, and then the veneer strips applied with the glue are dried at a low temperature below 60°C to a moisture content of below 16%;

[0077] c. Blank assembly, the veneer strips are quantified according to the set material density, and stacked to form blanks; the blank assembly method is to assemble the blanks along the length direction of the veneer strips, and the veneers are relatively disordered and naturally adjacent;

[0078] d, cold pressing, eucalyptus wood is sent into the mold of press and carry out cold pressing, and described pressure is greater than 20MPa; Wherein the inner film of mold i...

Embodiment 2

[0085] a, material selection, picking up the eucalyptus leftovers produced during the manufacture of veneers, the thickness of the eucalyptus leftovers is between 0.5mm-3mm, and the width of the veneer strips is not equal between 5mm-100mm;

[0086] b. Sizing;

[0087] c, forming blanks, stacking carbonized eucalyptus wood along its length direction to form blanks;

[0088] D, cold pressing, eucalyptus is sent into the mold of press and carry out cold pressing, and described pressure is greater than 20MPa;

[0089] f. Curing, the mold with the blank is heated and solidified.

Abstract

The invention discloses a method for manufacturing recombined hardwood. The method is characterized by comprising the following steps of: a, selecting gum wood with thickness of between 0.5 and 3 millimeters and width of between 5 and 100 millimeters; b, sizing; c, assembling, namely arranging and assembling the gum wood along the length direction; d, performing cold pressing, namely conveying the gum wood into a die of a press to perform cold pressing, wherein the pressure is more than 20MPa; and e, curing, namely heating the die filled with the blank to cure the blank. The sheared or rotary-cut fast-growing low juvenile gum wood or aspen wood of a made forest is used as a production raw material in the method, and the production raw material can be felled in 4 to 8 years, so the using cycle is greatly shortened, and the economic benefit is improved.

Description

technical field [0001] The invention relates to a wood manufacturing and processing method, in particular to a recombined hardwood processing method. Background technique [0002] At present, since natural forests are prohibited from being felled in my country, there is a shortage of hard solid wood for furniture, flooring, decoration, and building structures. More than 50% of the raw materials need to be imported. For direct processing, most of the time it is only used for papermaking or for the processing of laminate core materials. [0003] Due to the characteristics of the fast-growing wood itself, it has the following processing difficulties: ①Because the fast-growing wood grows fast, the density of the core layer and the outer layer are inconsistent, and the density error is 0.15-0.3, and it is easy to crack during drying; ②The fast-growing wood has too many dead knots, On average, there are hundreds of them per square meter, and they will fall off once dry, forming ho...
