A method for desugaring bamboo, and a method for preparing bamboo tow for antiseptic bamboo boards

Abstract

The invention relates to the technical field of bamboo processing, and more specifically, the invention relates to a method for desugaring bamboo and a method for preparing bamboo strands for antiseptic bamboo boards. Using a new type of deep eutectic solvent as a solvent, coupled with ultrasonic enhancement, and mild treatment conditions, the dissolution of sugars in the non-aqueous phase of bamboo and the hydrolysis of the controllable degree of polymerization can be achieved, and high value-added xylo-oligosaccharide by-products can be co-produced, avoiding the extraction liquid The composition is complex and difficult to deal with; at the same time, the deep eutectic solvent used in the bamboo desugaring process can be recycled after simple treatment. The bamboo material desugaring method of the present invention is used to treat the bamboo material, which can effectively improve the anti-corrosion and anti-mildew properties of the bamboo material, and can be widely used in the production of high-resistant outdoor landscape materials and indoor household materials. In addition, the whole production process is simple and easy, and the bamboo tow does not need to be degreened and yellowed, and the utilization rate of raw materials is high.

Description

technical field [0001] The invention relates to the technical field of bamboo processing, and more specifically, the invention relates to a method for desugaring bamboo and a method for preparing bamboo strands for antiseptic bamboo boards. Background technique [0002] Carbonization and steaming are the most commonly used methods to obtain bamboo tow for anti-corrosion bamboo boards. Carbonization can decompose the nutrients in bamboo to achieve the effect of anti-corrosion and anti-mildew of bamboo. The carbonized bamboo tow only needs to add a small amount of preservatives or even no preservative treatment, and can be directly used to produce anti-corrosion bamboo boards; However, the carbonization process will obviously change the mechanical properties and original color of the bamboo tow, and the degree of carbonization has a significant impact on the anti-corrosion and anti-mildew effects of bamboo chips and its material properties, thus affecting the quality of bamboo...

Carbonization can decompose the nutrients in bamboo to achieve the effect of anti-corrosion and anti-mildew of bamboo. The carbonized bamboo tow only needs to add a small amount of preservatives or even no preservative treatment, and can be directly used to produce anti-corrosion bamboo boards; However, the carbonization process will obviously change the mechanical properties and original color of the bamboo tow, and the degree of carbonization has a significant impact on the anti-corrosion and anti-mildew effects of bamboo chips and its material properties, thus affecting the quality of bamboo boards. During the processing of bamboo, a large amount of carbonized smoke will be generated, which is not easy to handle

The cooking treatment is to firstly cook the bamboo sheet with water to remove most of the sugar and other nutrients, and then impregnate it with preservatives to achieve the purpose of anti-corrosion and anti-mildew; however, the process parameters and methods of the cooking process and anti-corrosion impregnation process are different. 1. The different types of preservatives have an impact on the mechanical strength, anti-corrosion performance, and environmental performance of bamboo, and a large amount of cooking wastewater will be generated during the treatment of bamboo by cooking, which is not easy to handle.
