溶剂汽相法马尾松脱脂工艺研究

Study on solvent vapor phase method deresining technology of Masson pine

马尾松是中国主要的人工林树种,其蓄积量最大,分布地域最广。但由于富含树脂,其用途受到很大限制,因此松木脱脂成为提高其利用价值的重要手段。基于传统的脱脂方法不甚理想的状况,作者探讨了一种新的脱脂工艺方法——溶剂汽相法。该方法不仅能保证脱脂效果,而且降低了加工成本。

The Masson pine is a main kind of plantation tree in our country, which is rich in quantity and distributes most widely. But because of containing rich resin, its usage is very limited, the deresination of pine becomes very important to increase its usage. The paper approaches a new kind of deresination method——Solvent Vapor Phase Method. The method reduces the cost based on high deresination rate.
