马尾松木材性质特点及改性研究现状

Current Research on Properties and Modification of Masson Pine Wood

马尾松是我国分布最广泛的人工速生树种之一。为了充分利用马尾松资源,提高马尾松木材的品质,实现木材供需平衡,迫切需要对马尾松木材进行改性处理。文中首先从力学、化学和解剖3个方面对马尾松人工林木材的材性进行描述;其次,从脱脂改性、非浸渍改性和浸渍改性3个方面阐述马尾松木材改性研究进展,指出经过木材改性处理后能显著提升马尾松木材的性能;最后,提出今后马尾松木材改性的发展方向,以期促进马尾松的进一步综合利用。

Masson pine(Pinus massoniana Lamb.) is one of fast-growing tree species that has been the most widely used for plantation in China.There is an urgent need to modify Masson pine wood in order to enhance its quality,properly utilize Masson pine resources,and address the imbalance between supply and demand for timber.The properties of Masson pine wood are described in terms of mechanical,chemical,and anatomical dimensions,and then the research progress in Masson pine wood modification is also expounded,including the degreasing modification,non-impregnation modification,and impregnation modification.At the end,this paper proposes future directions for Masson Pine wood modification,with a view to boost the multi-domain utilization of Masson pine.
