Embodiment 1

[0027] According to the size specifications of the product, the requirements of the process or equipment performance, before the wood bundles are rolled, the small-diameter logs and branch wood are weighed and mixed at a mass ratio of 1:4-5, and then cut into 1m long wooden raw materials. Small-diameter wood and branch wood have small diameters and few and inconspicuous growth defects, as long as the extra-large knots are cut off. Soak the cut-off short material in water at 45-50°C for 3 hours, then raise the water temperature to 90-95°C at a heating rate of 10-15°C / h, and then keep it warm for 4 hours.

[0028] After the above operations, the hardness of the wood raw material is reduced, the toughness is increased, the wood fragments produced during rolling and torsion are reduced, and the power consumption of the subsequent rolling and torsion process is reduced, which facilitates small-diameter logs and branches to achieve wood beams of similar size specifications. Small-di...

Embodiment 2

[0041] Before the wood bundles are rolled, small-diameter logs and branch wood are weighed and mixed at a mass ratio of 1:4-5, and then cut into 2m-long woody raw materials. Small-diameter wood and branch wood have small diameters and few and inconspicuous growth defects, as long as the extra-large knots are cut off. Soak the chopped short material in water at 45-50°C for 4 hours, then raise the water temperature to 90-95°C at a heating rate of 10-15°C / h, and then keep it warm for 5 hours.

[0042] After the above operations, the hardness of the wood raw material is reduced, the toughness is increased, the wood fragments produced during rolling and torsion are reduced, and the power consumption of the subsequent rolling and torsion process is reduced, which facilitates small-diameter logs and branches to achieve wood beams of similar size specifications. Small-diameter logs usually refer to logs with a diameter class less than 50mm, which have low utilization value in wood pro...

Abstract

The invention relates to scrimber and a preparation method thereof. According to the scrimber, logs and brush wood with a small diameter are taken as woody raw materials, the woody raw materials are cut off, soaked and ground to form wood bunches which are not broken in the longitudinal direction or loose in the transverse direction and are connected in a staggered manner, the wood bunches are separated, dried, glued, assembled, paved and hot-pressed through turning, pressing and twisting, and the scrimber is prepared. The scrimber has the main performance as follows: the thickness ranges from 15 mm to 25 mm, the density ranges from 1.1 g / cm<3>-1.2 g / cm<3>, the internal bond strength ranges from 4 MPa to 5 MPa, the static bending intensity ranges from 120 MPa to 130 MPa, the thickness swelling rate of the scrimber after water absorption is 4%-5%, and the formaldehyde emission ranges from 1.2 mg / L to 1.4 mg / L. The scrimber and the preparation method have the advantages that the scrimber product prepared with the simple and efficiency process has better mechanical strength and size stability and is suitable for large-scale production, the economic benefits are high, the utilization efficiency and the economic value of wood are improved, and convenience is provided for production, utilization and popularization of the scrimber.

Description

【Technical field】 [0001] The invention relates to the field of wood-based panels, in particular to a recombined wood and a preparation method thereof. 【Background technique】 [0002] With the rapid development of social economy and the improvement of people's living standards, people's demand for furniture and other indoor and outdoor decoration materials is also increasing. However, due to the unrestrained use and consumption of natural resources by humans, timber resources are increasingly scarce. The manufacture of particleboard, fiberboard and other wood-based panels all disrupt the natural arrangement of wood fibers, of course the performance is destroyed, and then they are rearranged and glued together with great effort. In order to make full and reasonable use of the original characteristics of wood raw materials, it is envisaged to design and develop a product similar to natural wood—recombined wood—under the condition of not disturbing the original wood fiber arran...
