Problems solved by technology

However, because the material and processing characteristics of bamboo are very different from those of wood, there are no relevant products and manufacturing technology reports that can fully meet the needs of new structures and decorative plywood.

Embodiment 1

[0017] Bamboo and wood veneer are used as raw materials to manufacture structural and decorative bamboo-wood composite plywood. The structure and manufacturing method of bamboo-wood composite plywood for structure and decoration are as follows:

[0018] a. Cut the wood into veneers; cut the bamboo into strips, and weave them into bamboo curtains with cotton threads. The moisture content of the veneer and bamboo curtain is controlled at about 8%;

[0019] b. Use 2 layers of bamboo curtains and 11 layers of wood veneer to form the core layer (1);

[0020] c. The two outer layers (2) each use two layers of bamboo curtains, and the texture directions of the two layers of bamboo curtains are in the same direction when forming the billet;

[0021] d. Each of the two surface layers (3) uses a layer of wood veneer with a thickness of 1.5mm, and the grain direction of the wood veneer is perpendicular to the grain direction of the bamboo curtain when forming the billet;

[0022] e. O...

Embodiment 2

[0034] Since the grain direction of the wood veneer must be perpendicular to the grain direction of the bamboo curtain when the billet is assembled, when the grain of the bamboo (curtain) is parallel to the length direction of the finished product, the width of a single wood veneer generally cannot completely cover the board surface and It needs to be extended horizontally. In order to ensure the flatness of the joints at the horizontal joints of the wood veneers, a slope of 1:8-10 can be milled at the transverse joints of the wood veneers, so that adjacent wood veneers can be overlapped to form blanks.

[0035] All the other are with embodiment 1.

Embodiment 3

[0037] In order to improve the physical and mechanical properties and transverse strength of the finished product to a higher extent, four layers of bamboo screens can be used for the two outer layers (2). When assembling the blanks, the textures of the three layers of bamboo curtains on the outer surface can be made in the same direction, and the texture direction of the innermost layer of bamboo curtains is perpendicular to the texture direction of the other three layers of bamboo curtains; it is also possible to make the two layers of bamboo curtains on the outer surface and the innermost bamboo curtains The grain of the bamboo curtain of 1 layer is in the same direction, and the grain direction of the bamboo curtain of the remaining 1 layer is perpendicular to the grain direction of other 3 layers of bamboo curtains.

[0038] All the other are with embodiment 1.

Abstract

The invention is a structure mainly made of wood and bamboo and relates to decorative wood and bamboo complex gluing sheet and its production technique. Its feature is that the core layers are constructed with normal multi-layer wood, bamboo complex material or multi-layer wood sheets. Outer layer has one or more than one bamboo screen. The outside two bamboo layers is laid equidirectionally to perform when the outer layer has more than on bamboo screen. The face layer is a single wood sheet with perpendicular veins to that of bamboo screens. The coat layer is soaking decorative paper. The product is obtained through processes of gluing, performing, pressing and then once or twice of heat press.

Description

1. Technical field [0001] The invention belongs to the wood-based panel manufacturing technology in the wood industry. 2. Background technology [0002] With the development of science and technology, the continuous improvement of economic and consumption levels, in many occasions, it is often required to have high longitudinal and transverse strength (MOR) and elastic modulus (MOE) for ordinary structural plywood, and further proposed High surface quality (mainly surface flatness and smoothness, etc.) requirements are imposed; while for decorative plywood with high surface quality requirements, higher strength index requirements are proposed. [0003] On the other hand, due to the shortage of global timber resources, there are fewer and fewer high-quality timbers that can be used to manufacture modern structural and decorative plywood that meet the above-mentioned stringent requirements. Therefore, the social demand for finding new high-quality wood substitute raw material...
