Bamboo chip secondary carbonization process

Abstract

The invention discloses a bamboo chip secondary carbonization process. The bamboo chip secondary carbonization process includes the following steps that firstly, bamboo chips obtained after slicing are placed in a carbonized oven for primary carbonization at the temperature controlled to range from 120 DEG C to 140 DEG C for 2 hours to 3 hours; secondly, after the bamboo chips obtained after primary carbonization are completely cooled, secondary carbonization is conducted, in the secondary carbonization process, the bamboo chips are carbonized at the high temperature ranging from 110 DEG C to 125 DEG C for 2 hours to 2.5 hours, and then the bamboo chips are carbonized at the temperature ranging from 130 DEG C to 135 DEG C for 1 hour to 1.5 hours. By the adoption of the secondary carbonization process, organic matter such as sugar, starch and protein in bamboo wood is decomposed in a high-temperature and high-humidity environment, fungi and other insects lose nutrient sources, eggs and fungi attached to the bamboo wood are killed, and therefore machining quality of the bamboo chips is guaranteed and the service life of products is prolonged; in addition, due to the adoption of secondary carbonization, colors of the bamboo chips with different ages and in different positions tend to be consistent, the color difference is reduced, and attractiveness of floors is improved.

Description

technical field [0001] The invention relates to the technical field of comprehensive treatment of bamboo and wood, in particular to a secondary carbonization process of bamboo chips. Background technique [0002] As a common plant, bamboo has very broad application value in industrial applications, especially after bamboo is processed, it can be made into various products such as furniture, floors, utensils, etc. Compared with wood products, it is cheap, Multiple advantages such as light weight and wide source of materials. Carbonization is a very important link in the processing of bamboo products. Generally speaking, there is still the problem of unstable physical properties of the bamboo chip surface. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a kind of secondary carbonization process of bamboo chips, which can further stabilize the physical properties of the bamboo chip surface, and at the same time intensify...

[0002] As a common plant, bamboo has very broad application value in industrial applications, especially after bamboo is processed, it can be made into various products such as furniture, floors, utensils, etc. Compared with wood products, it has low price, Multiple advantages such as light weight and wide source of materials. Carbonization is a very important link in the processing of bamboo products. However, in the prior art, there is generally only one carbonization. Although the bamboo chips after one carbonization treatment can also meet the processing requirements, but In general, there is still the problem of unstable physical properties of the bamboo surface
