摘要
目的归纳国内外现有热处理工艺对竹材理化性能的影响的研究进展,分析不足,并提出热处理竹材作为代木材料在包装领域的未来研究趋势。方法综述不同热处理竹材工艺(包含时间条件、温度条件、介质种类)的研究现状,总结竹材理化性能的变化特点。结果当前热处理技术作为环保简易的竹改性技术表现出一定优势,但单一的工艺条件对竹材原有性能会产生负向影响,需对工艺参数和反应条件进行开发改进,并设计相应的制备装置。结论采用热处理条件多线程综合工艺可以在优化竹材性能的同时,保持甚至降低中高温对竹结构的破坏,从而增加热处理竹材的使用年限,并拓展其使用领域。
The work aims to summarize the existing heat treatment process of bamboo,the physical and chemical properties of bamboo under different treatment temperature,analyze their shortages and then put forward the future research trend of heat-treated bamboo slabs as wood substitute material in packaging.The research status of different heat treatment of(including time,temperature and medium of treatment)bamboo and the characteristics of physical and chemical properties of bamboo were summarized.The current heat treatment technology had some advantages as an environmentally friendly and simple bamboo modification technology,but the single process condition had a negative impact on the original properties of bamboo,so it was necessary to develop and improve the process parameters and reaction conditions,and design the corresponding preparation device.The multi-thread integrated process can optimize the properties of bamboo while maintaining or even reduce the damage of bamboo structure at medium and high temperature,thus increasing the service life of heat-treated bamboo and expanding the application field.
