摘要:

本文对纳米和微米技术在木材工业上的应用前景进行展望,预测未来纳微米技术可能对木材工业产生的影响。利用纳微米技术可能形成造纸的高得浆率方法,木材在变成纳微米尺寸后,木材的材料特异性质、尺寸效应及其变化机理,以及木材改性的显微结构关系可能使木材改性出现突破性进展。当木粉变成纳微米的粒度后,原木材理化指标发生变化,在细粉状态下进行木材液化可以改变木材液化的方式和成本,使木材液化真正工业化。在复杂木雕制品加工中,采用RPM技术利用直接CAD将纳微米木粉形成复杂木雕制品,可能开创一种新的木材加工方法。利用木材细胞的自组装方式可形成新的木基复合材料,纳米木粉生产的无污染胶粘剂可能代替含甲醛的有毒胶,胶粘剂的绿色革命可能从木材的纳微米技术开始。

Abstract:

As a new breakthrough point, nanometer technology will bring new technology revolution. This paper will look into the development in nm and μ technology and it's prospect applying to wood industry, and forecast the influence that the nm technology can bring to the wood industry in the future. Using the nanometer and micrometer technology can get high rate pulp in papermaking, if wood size is measured in nm, the relations of wood's material distinctive character, size effect and modified wood, and the microscopic construct of modified wood can make the modified have a breakthrough progress. When wood powder change into nm grain, the original wood's physical and chemical characters are all varied. Having the wood liquefaction at the fine powder state can change the way and cost of the wood liquefaction, and can make wood liquefaction really realized industrialization. In complicated wood carve products process, using RPM technique and direct CAD make the nanometer and micronmeter wood powder to form complication wood carve products, which can initiate a new wood converting way. Using wood cell's self combine way can form new wood matrix composites, nm wood powder production's bonding agent has no pollution, it can replace the poisonous bonding that contains formaldehyde, bonding agent's Green Revolution can start from nanometer and micrometer technology.
