Embodiment

[0016] Embodiment, the high-efficiency carbonization of bamboo tube and the non-crack treatment method are as follows:

[0017] (1) Fresh bamboo tubes with a diameter of 100mm (not more than 20 days after felling) are cut into 1800mm long according to the requirements, and the long drill bit is used to drill holes in the bamboo joints to open it longitudinally, or the upper and lower parts of the bamboo joints are cut from the bamboo green layer. Drill holes to the yellow layer of bamboo, which can ensure the communication between the inside of the bamboo tube and the outside;

[0018] (2) Stack the bamboo tubes and put them into the high-pressure tank, place the bamboo tubes on the trolley, push them into the high-pressure tank, and close the tank door;

[0019] (3) High-temperature softening and carbonization treatment in the round bamboo tube high-pressure tank, the temperature of 180 ℃ high-temperature steam is introduced into the tank, and the cold air and condensed water...

Abstract

The invention provides an efficient carbonization and crack-free treatment method of bamboo pipes. The method comprises the following process steps that 1, the fresh bamboo pipes are drilled; 2, the bamboo pipes are stacked and enter a high-pressure tank; 3, the round bamboo pipes are softened and carbonized at a high temperature in the high-pressure tank; and 4, the round bamboo pipes are dried. The fresh round bamboo pipes are placed into a high-temperature saturated steam tank with the temperature ranging from 140 DEG C to 190 DEG C, high-temperature steam is utilized for fast heating, softening points of lignin, cellulose and hemicellulose can be reached fast, meanwhile, the hemicellulose is hydrolyzed fast at such a high temperature and humidity, and therefore the purpose of efficient carbonizing within a short time is achieved. Water in the bamboo pipes is drained by means of dry hot steam, the bamboo pipes are dried and shrunk and cannot cause cracking, thus, fast carbonization treatment and softening treatment are achieved, and the crack-free carbonized round bamboo pipes manufactured through the method are better in size stability and suitable for manufacturing artware, furniture, bamboo buildings and outdoor landscape, and have anticorrosion and anti-moth performance. The better processing method is provided for the bamboo industry.

Description

technical field [0001] The invention relates to a high-efficiency carbonization and crack-free treatment method for bamboo tubes, and belongs to the technical field of bamboo processing in the wood industry. Background technique [0002] Home decoration, furniture and outdoor wood materials mainly use natural solid wood, such as African pineapple grid, Burmese teak, South American iber and American oak and other large-diameter hard broad-leaved materials, as well as Russian sylvestris pine and American southern pine treated with preservatives. Wait. The use of preservatives containing toxic ingredients such as heavy metals will cause the loss of rainwater during use and affect the ecological environment. However, with the development of society and economy and the increase of population, the global demand for wood continues to grow. Due to the increasing pressure on the global environment, the governments and people of various countries have strengthened their environmental...
