Embodiment 1

[0031] The production process of recombined bamboo board comprises the following steps in turn,

[0032] a, material selection: select bamboos with a diameter at breast height greater than 60 mm, and reserve them;

[0033] B, material cutting: the bamboo obtained in step a is cut off to obtain a bamboo section, the length of the bamboo section is equal to the size of the plate to be processed plus the size of the subsequent processing allowance, and the size of the subsequent processing allowance is 5% of the length of the bamboo section ;

[0034] C, strip: the bamboo section obtained in step b is cut longitudinally along the axis to make bamboo slices, the central angle of the cross-section of the bamboo slices is 30 degrees, because the shape of the bamboo is cylindrical, by reducing the bamboo The central angle of the cross-section of the bamboo slices makes the bamboo slices more flat, reduces the amount of material removal in subsequent processing, and improves the util...

Embodiment 2

[0048]The production process of recombined bamboo board comprises the following steps in turn,

[0049] a, material selection: select bamboo with a wall thickness greater than 3 mm, and reserve it;

[0050] B, material cutting: the bamboo obtained in step a is cut off to obtain a bamboo section, the length of the bamboo section is equal to the size of the plate to be processed plus the size of the subsequent processing allowance, and the size of the subsequent processing allowance is 10% of the length of the bamboo section ;

[0051] C, strip: the bamboo section obtained in the step b is cut longitudinally along the axis to make bamboo chips, the central angle of the cross-section of the bamboo chips is 60 degrees, because the bamboo chips will be rough planed in the follow-up processing process, The central angle of the cross-section of the bamboo slices is 60 degrees, which improves the rough planing efficiency of the bamboo slices and reduces the manufacturing cost of the ...

Embodiment 3

[0065] The production process of recombined bamboo board comprises the following steps in turn,

[0066] a, material selection: select bamboo with a wall thickness greater than 3 mm, and reserve it;

[0067] B, material cutting: the bamboo material obtained in step a is cut off to obtain a bamboo section, the length of the bamboo section is equal to the size of the plate to be processed plus the size of the subsequent processing allowance, and the size of the subsequent processing allowance is 8% of the length of the bamboo section ;

[0068] C, strip: the bamboo section obtained in the step b is cut longitudinally along the axis to make bamboo chips, the central angle of the cross-section of the bamboo chips is 60 degrees, because the bamboo chips will be rough planed in the follow-up processing process, The central angle of the cross-section of the bamboo slices is 60 degrees, which improves the rough planing efficiency of the bamboo slices and reduces the manufacturing cos...

Abstract

The invention relates to the field of bamboo production, in particular to recomposed bamboo board producing process. The recomposed bamboo board producing process uses renewable bamboo as raw materials, the utilization rate of bamboo is high and can reach more than 90%, and resource waste is reduced. The density of recomposed bamboo boards manufactured in the recomposed bamboo board process is high as 1200kg / m<3> and is more than 1.6 times of the density of ordinary bamboo floors. The recomposed bamboo boards have the advantages of being high in hardness, high in strength, high impact toughness and wearproof. The recomposed bamboo boards manufactured in the recomposed bamboo board producing process further have the advantages of being capable of resisting to water absorption, free of deformation and the like. Tests show that the thickness expansion rate is only 0.4% after the recomposed bamboo boards absorb water for 24 hours and is far better than and smaller than the European standard of 2.0%. The free formaldehyde emission of the recomposed bamboo boards manufactured in the recomposed bamboo board producing process is below 0.4mg / L, so that harm of formaldehyde to people is reduced.

Description

technical field [0001] The invention relates to the field of bamboo production, in particular to a production process for recombined bamboo boards. Background technique [0002] Reconstituted bamboo is a new type of green environmental protection material developed in recent years, and it is a new type of building decoration material that fills the gap at home and abroad. [0003] Reconstituted bamboo is a new type of bamboo wood-based panel processed from bamboo as raw material according to the manufacturing process and principle of recombined wood. And maintain the original arrangement of fibers in the form of loose mesh fiber bundles, and then dried, sizing, formed into blanks, cold pressed or hot pressed into plates or other forms of materials, the biggest feature of recombined bamboo is that it can be fully and rationally utilized The inherent characteristics of bamboo fiber materials not only ensure the high utilization rate of bamboo, but also retain the original phy...
