Embodiment 1

[0017] The bamboo chip secondary carbonization process of the present embodiment comprises the following steps:

[0018] Step 1: Put the bamboo chips obtained after the fragments into a carbonization furnace for a carbonization, the temperature is controlled at 120°C, and the time is 3 hours;

[0019] Step 2: After the primary carbonized bamboo slices are completely cooled, carry out secondary carbonization. In the secondary carbonization, carbonize the bamboo slices at a high temperature of 110°C for 2.5 hours, then raise the temperature to 130°C for 1.5 hours .

[0020] In this embodiment, during the carbonization process of step 2 and step 3, the humidity is kept at 75%.

Embodiment 2

[0022] Bamboo chip secondary carbonization process in the present embodiment, comprises the following steps:

[0023] Step 1: Put the bamboo chips obtained after the fragmentation into a carbonization furnace for a carbonization, the temperature is controlled at 140°C, and the time is 2 hours;

[0024] Step 2: After the primary carbonized bamboo slices are completely cooled, carry out secondary carbonization. In the secondary carbonization, carbonize the bamboo slices at a high temperature of 125°C for 2 hours, then raise the temperature to 135°C for 1 hour .

[0025] In this embodiment, during the carbonization process of Step 2 and Step 3, the humidity is kept at 85%.

Embodiment 3

[0027] The bamboo chip secondary carbonization process of the present embodiment comprises the following steps:

[0028] Step 1: Put the bamboo chips obtained after the fragmentation into a carbonization furnace for a carbonization, the temperature is controlled at 130°C, and the time is 2.5 hours;

[0029] Step 2: After the primary carbonized bamboo slices are completely cooled, carry out secondary carbonization. In the secondary carbonization, carbonize the bamboo slices at a high temperature of 120°C for 2.2 hours, then raise the temperature to 132°C for 1.2 hours .

[0030] In this embodiment, during the carbonization process of Step 2 and Step 3, the humidity is kept at 80%.

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...
