松香、松节油生产,是综合利用森林资源的有效途径。开展采脂和松香生产,对轻、化工业的发展起着积极的作用。1980年以来,采用下降法采脂和滴水法炼香,进行了试生产,积累了经验,取得了一定成绩。松脂是从松树中分泌出来的天然产物,是提炼松香、松节油的原料。松脂刚从树体流出时为白色或浅黄色液体,随着时间的增长,松节油挥发,松脂变得粘稠,颜色逐渐加深,最后成为黄色凝块。松脂主要由树脂酸和萜烯组成,尚含一些树胶、色素和单
Rosin, turpentine production, is an effective way to comprehensive utilization of forest resources. To carry out fat production and rosin production, light and chemical industry play a positive role. Since 1980, the method of taking down fat and drip method has been adopted for refining incense, and the trial production has been carried out. The experience has been accumulated and certain achievements have been made. Turpentine is a natural product secreted from pine trees and is a raw material for refining rosin and turpentine.
