Embodiment 1

[0036] Embodiment 1: a kind of average density bamboo particle board production method, it comprises the following steps successively:

[0037] (1) Material selection, the raw material is scraps from the production process of bamboo products, such as bamboo scraps produced during the production of bamboo mats;

[0038] (2) For the first screening, use a drum type screening machine to screen the above scraps to remove impurities such as stones and metal particles in the scraps, leaving only bamboo debris;

[0039] (3) For the first drying, place the bamboo chips obtained through the first screening in an oven, control the temperature in the oven to 80°C, and adjust the moisture content of the bamboo chips to 15%;

[0040] (4) The second screening is to re-screen the bamboo debris obtained through the first drying to obtain bamboo debris with a particle size of less than 0.9cm, and the screening machine used is a vibrating screening machine;

[0041] (5) For the second drying, ...

Embodiment 2

[0054] Embodiment 2: a kind of uniform density bamboo particleboard production method, it comprises the following steps successively:

[0055] (1) Material selection, the raw material is scraps from the production process of bamboo products, such as bamboo scraps produced during the production of bamboo mats;

[0056] (2) For the first screening, use a drum type screening machine to screen the above scraps to remove impurities such as stones and metal particles in the scraps, leaving only bamboo debris;

Abstract

The invention relates to a machining process for an artificial board, in particular to a method for producing a uniform-density bamboo shaving board. The invention is realized through the following technical scheme: the method for producing the uniform-density bamboo shaving board is characterized by sequentially comprising the following steps of: (1) selecting materials; (2) first screening; (3) first drying; (4) second screening; (5) second drying; (6) sizing; (7) hot-pressing; and (8) refrigerating. The uniform-density bamboo shaving board has the advantages of density uniformity, high dimensional stability and high static bending strength.

Description

technical field [0001] The invention relates to a wood-based panel processing technology, in particular to a production method of average-density bamboo particleboard. Background technique [0002] Bamboo is an important part of my country's forest resources, and the annual output of my country's wood is about 50 million m 3 , The felling of moso bamboo is about 5 million tons, accounting for one tenth of the wood production, and the growth rate of bamboo is faster than that of ordinary fast-growing wood. Therefore, the rational use of bamboo is of great significance to solve the shortage of wood resources in our country. [0003] The isotropic mechanical properties of bamboo are generally higher than that of wood. However, since the macroscopic structure of bamboo is a hollow cylinder, although the mechanical properties of the bamboo wall are very good, the bamboo itself cannot bear a large load, nor can it be sawn into a board like wood; therefore, research and manufactur...
