Method for processing black bamboo

Abstract

The invention discloses a processing method of a black bamboo, which comprises the following processing steps: (1) the bamboo is soaked in a solution, wherein, the soaking process is carried out in a temperature of 0-100 DEG C; the volume ratio between the bamboo and the solution is (0.01-10): (2-200); after soaking for 1-7 days, the bamboo is taken out to derive soaking bamboo; (2) the soaking bamboo is carbonized in the temperature of 100-200 DEG C for 0.5-10h with hot water vapor as a medium, thus acquiring the carbonization bamboo; (3) a drying method is adopted to reduce the moisture content of the carbonization bamboo to 4-14 to derive the black bamboo. The black bamboo processed by the method has a mechanical strength less than 10 percent, takes on black, grey or dark grey and is provided with faint scent of the bamboo; furthermore, the black bamboo is also mildewproof, free from brightness reversion in 10 years and toxic and side effects, which is an ideal material of black bamboo products. The processing method of black bamboo has the advantages of simple process, good controllability, low cost, no expensive equipment and industrialization facilitating, thereby having a broad application prospect.

Description

technical field [0001] The invention relates to a method for processing and preparing black bamboo. Background technique [0002] In order to alleviate the increasingly tense contradiction between timber supply and demand and realize "replacing wood with bamboo", the Chinese government plans to rebuild and build 1.2 million hectares of bamboo forest bases within 15 years, and establish a complete bamboo research and development network to promote the development of the bamboo industry. For example, in Jiangxi Province in 2005, the existing bamboo forest area was about 10.64 million mu, with a total accumulation of 1.04 billion Moso bamboos. To develop the forestry industry, initially build a standardized and orderly, intensively managed, rationally structured and dynamic forestry industry system, transform a province with a large forestry resource into a province with a large forestry industry, and add greenness and wealth to Jiangxi. By 2010, the total forestry industry in ...

Problems solved by technology

[0004] However, whether bamboo is used as a building material or a furniture or handicraft material, there are three natural defects: easy to grow insects, mold, cracks, and deformation. In the process of industrialization, it has the same environmental problems as the wood industry: abuse of paint, adhesives, There are many preservatives and processing waste. Such artificial cost increases lead to poor industry competitiveness and incomplete market, so that the bamboo industry cannot truly become a complete and sustainable industry.
