【摘要】 松树受伤时会分泌大量的松脂——松香、松节油的混合物,从而对伤口起到防腐和促进愈合的作用。因此,松香是一种天然的木材保护剂。本文以两种水基松香制剂为原料,通过抑菌实验、处理木材的吸湿实验及耐腐能力实验,说明了松香具有一定的抑菌性能,并能够赋予木材一定的阻湿能力,从而对木材起到保护作用。4%两种水基松香制剂处理木材,耐腐能力均达到Ⅱ级(耐腐级)。我国是松香生产和原料出口大国,森林蓄积量低。松香资源丰富,价格低廉,环境友好。开展松香在木材防腐中的应用研究具有重要意义,应得到更多的关注。更多还原

【Abstract】 When pines are wounded, they will secret gum, which is a mixture of rosin and turpentine, in order to protect them selves from fungi or insects, and accelerate wood healing. To some extend, rosin is a natural preservative. In this paper, the effect of rosin on wood protection was studied through the tests of inhibition on wood decay fungi, moisture absorption of treated wood, and the resistance of soil blocks to wood decay fungi. China is a major country for rosin production and export. Meanwhile, China is short of forest resource. Rosin is abundant, cheap and environment-friendly. Applying rosin to protect wood is very meaningful and should get more attention.更多还原
