Bamboo desugaring method and preparation method of bamboo filament bundle for anti-corrosion bamboo board

Abstract

The invention relates to the technical field of bamboo processing, in particular to a bamboo desugaring method and a preparation method of bamboo tows for an anti-corrosion bamboo board. A novel deep-eutectic solvent is used as a solvent with ultrasonic reinforcement, so that the treatment condition is mild, dissolution and controllable polymerization degree hydrolysis of carbohydrates in non-aqueous-phase bamboo are achieved, a high-additional-value xylooligosaccharide byproduct is co-produced, and the problem that an extracting solution is complex in component and difficult to treat is solved; meanwhile, the eutectic solvent used in the bamboo desugaring treatment process can be recycled through simple treatment. By means of the bamboo desugaring method, the corrosion resistance and mildew resistance of the bamboo can be effectively improved, and the bamboo desugaring method can be widely applied to production of high-resistance outdoor landscape materials and indoor household materials. In addition, the whole production process is simple and feasible and green and yellow removal of bamboo tows is unnecessary, so that the raw material utilization rate 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.
