Abstract

The invention belongs to the field of wood processing, and particularly relates to a wood veneer treatment method and reconstituted wood. The method comprises the step of placing a wood veneer in a rolling machine according to the fibre cross-grain direction thereof, and rolling to obtain a treated veneer, wherein a roll gap of the rolling machine is 10-80% of a thickness of the wood veneer. With the adoption of the method provided by the invention, the wood veneer can be rolled into a broomed-meshy-structure veneer with fibres which are not broken in a longitudinal direction and loose in a transversal direction, a natural texture structure of raw wood is reserved, the rigidity of the veneer is eliminated, and an initial stress and a pressing pressure are reduced, thus the density uniformity of the pressed reconstituted wood is improved, and the warping and deformation of the reconstituted wood are reduced; meanwhile, the surface area of the treated veneer is increased, and glue dipping is more uniform, thus a cracking risk of the prepared reconstituted wood is reduced; and in addition, fine fibres in the treated veneer are mutually interleaved to increase an internal binding force, thus cracking and warping risks caused by the reconstituted wood are further reduced.

Description

technical field

[0001] The invention belongs to the field of wood processing, in particular to a wood veneer treatment method and recombined wood. Background technique

[0002] Recombined wood is a new type of wood material made of wood bundle units after dipping and pressing without disturbing the direction of wood fiber arrangement and retaining the basic characteristics of wood. It not only has the natural wood texture structure of logs, but also has It has higher strength than logs, and the size specifications of the products are also easy to adjust. At present, in the production process of recombined wood, there are problems such as long dipping time of wood bundle units, uneven dipping amount and uneven paving, which lead to easy cracking and wire skipping of the produced recombined wood products.

[0003] In order to improve the above shortcomings, the recombined wood with wooden veneer unit structure has been successfully developed. Although it can reduce the cracki...
