Degreasing and desugaring method of sympodial bamboo

Abstract

The invention relates to a degreasing and desugaring method of sympodial bamboo, which belongs to the technical field of processing and preservation of wood or similar materials. The degreasing and desugaring method is combined with the structural characteristics of the sympodial bamboo, and the two steps, namely high-temperature and high-pressure smoking and cooking, and high-temperature and high-pressure carbonization, are adopted for degreasing and desugaring the sympodial bamboo. In the step of high-temperature and high-pressure smoking and cooking, water and steam are simultaneously used for steam-boiling so as to strength the degreasing and desugaring; and in the step of high-temperature and high-pressure carbonization, the secondary degreasing and desugaring is performed on bamboo fiber, and exhaust is performed during the carbonization process multiple times, thereby removing lipids and sugars in the bamboo fiber to the greatest extent, simultaneously unifying the color of the bamboo fiber and performing the color matching on the bamboo fiber. According to the degreasing and desugaring method, simple equipment and the simple process are applied for performing the degreasing and desugaring treatment on the sympodial bamboo so as to realize anti-moth-eaten and anti-mildew effects, no preservative type substances are added during the treatment process, the high-temperature and high-pressure carbonization treatment is simultaneously adopted, the color matching can also be performed on the bamboo fiber, and the adding of a dyeing agent is not required, thereby being green and environmentally-friendly.

Description

technical field [0001] The invention belongs to the processing and preservation of wood or similar materials, and more specifically relates to a degreasing and desugaring method for clustered bamboo. Background technique [0002] With the development of society, people's demand for wood is increasing, but the amount of wood is far from meeting the needs of society. At the same time, due to slow growth of wood and long harvesting time, a large number of felling trees will cause soil erosion and ecological damage. Bamboo is a perennial fast-growing resource, suitable for artificial planting, and the harvesting period is short. Reasonable and orderly use of artificially planted bamboo will not cause damage to the ecological environment, and can partially replace the demand for wood in society. [0003] The Chinese patent "Preparation Process of High-density Bamboo Material" (200510018534) discloses a preparation process of high-density bamboo material, which also records the st...

Problems solved by technology

[0004] Clumping bamboos such as dragon bamboo grow fast, with high stems and thick diameters, and the output per unit area is several times that of the scattered bamboo species of my country's economic bamboo species. The fiber of clumping bamboo is thick, and the bamboo stem contains certain protein, amino acid, fat, acid-base substances and mineral elements. The content of cellulose, starch, resin and other polysaccharides in clumping bamboo is higher than that of moso bamboo, and it is easy to enzymatic rot and moth

[0005] The degreasing and desugaring process of clustered bamboo is very important in the preparation process of clustered bamboo integrated profiles. Due to the thick fibers of clustered bamboo and the high content of starch, acid-base substances, sugars and other substances, if the above-mentioned Chinese patent "High Density Bamboo Material Method" is used The method of degreasing and desugaring the scattered bamboo disclosed in "(200510018534) discloses that the method of degreasing and desugaring the scattered bamboo can not remove the sugar, starch, acid-base and other substances in the bamboo fiber well, resulting in the obtained The profiles are easy to crack and deform during the drying process, and the profiles are prone to mildew and insects, so they cannot be used. This is the main reason why clustered bamboo has not been developed and utilized for many years.
