Ladder-shaped bamboo original state recombined material and manufacturing method thereof

Abstract

The invention relates to a ladder-shaped bamboo original state recombined material and a manufacturing method thereof, which belong to the field of materials. The ladder-shaped bamboo original state recombined material is formed by orderly arranging and splicing smooth ladder-shaped bamboo boards which take bamboo outers as ladder-shaped upper bases and bamboo inners as ladder-shaped lower bases; and the ladder-shaped bamboo boards can take the shape of an isosceles trapezoid or a non-isosceles trapezoid. The ladder-shaped bamboo original state recombined material has the advantages: a rounded hollow bamboo slab is processed into the ladder-shaped bamboo board so as to carry out original state bamboo slab recombination on the basis of keeping the natural structure of the bamboo according to characteristics of hollowness and cone-shape of the bamboo and large differences of the bamboo outers, the bamboo inners and bamboo joints in terms of the metal property and the like; compared with the traditional rectangular (square) combination, the utilization rate is increased due to the original state combination; multiple geometric figure recombination can be realized, and the recombined bamboo material with high strength can be manufactured. The ladder-shaped bamboo original state recombined material can be used for replacing precious woods and various artificial slabs. The utilization rate of the bamboo resources is increased, and wood resources are saved. The invention also provides a manufacturing method of the recombined material.

Description

technical field [0001] The invention belongs to the field of materials, and relates to an original recombined material of trapezoidal bamboo, and also relates to a manufacturing method of the recombined material. Background technique [0002] my country is the world's largest bamboo resource-rich country. The bamboo processing industry has developed rapidly, but the utilization rate of bamboo is very low. Taking bamboo flooring as an example, the utilization rate of whole bamboo is less than 25%. Bamboo has the characteristics of rapid growth and short rotation period. Processing hollow bamboo into new composite materials has a good application prospect. Existing bamboo recombination technologies mainly include: [0003] (1) Rectangular recombination technology: Split the hollow bamboo into arc-shaped bamboo blanks (such as figure 2 shown), and then the bamboo blank is processed into a rectangular (or square) strip of a certain specification (such as Figure 4b As shown),...

Problems solved by technology

[0002] my country is the country with the largest bamboo resources in the world. The bamboo processing industry has developed rapidly, but the utilization rate of bamboo is very low. Taking bamboo flooring as an example, the utilization rate of whole bamboo is less than 25%.

Its disadvantages and deficiencies are: the arc-shaped bamboo blanks are cut into square strips, resulting in a lot of waste of raw materials, and the general utilization rate is less than 30%.

Although the utilization rate of this kind of reorganization is higher than that of rectangular reorganization, it still has the following disadvantages and deficiencies: 1) The accuracy of the inner arc and the outer arc is very high, and the processing is difficult; 2) The inner arc and the outer arc must be done Equal, the diameter requirements for round bamboo are consistent, which is not conducive to large-scale production

Its shortcomings and shortcomings are: the macrostructure of natural bamboo is destroyed, the "original state" of bamboo is lost, the surface quality is not good, and it cannot replace higher-grade solid wood

Its shortcomings and shortcomings are: it has lost the "original state" of bamboo, and it cannot be made into high-grade products that can replace wood
