松脂松脂pineoleoresin开割松树树体后流出来的含油树脂。是树木生理活动的产物，主要由萜类化合物组成。刚流出的松脂是无色透明的油状液体，暴露在空气中，随着萜烃化合物逐渐挥发而变稠，最后成为白色或黄色的固态物质——毛松香。松脂是生产松香和松节油的原料。图1 下降式割面采脂松树针叶进行光合作用生成的糖类，再经过复杂的生物化学变化，在木材的薄壁细胞中形成松脂，通过泌脂细胞壁渗入树脂道。树脂道纵横交错形成树脂道系。采割松脂时，只要割伤树干外缘木质部，松脂通过树脂道系外流。松脂主要由树脂酸和萜烃组成，此外还含有少量杂质和水分。它们的含量因树种、产地、采脂方法和贮存期而异。开割松树树干，收集分泌出松脂的全部作业，称为采集。简称采脂。松树胸径一般在20厘米以上开始采割。按割期长短分长期采脂（10年以上）、中期采脂（6～9年）和短期采脂（3～5年）。按采割特征有常规法、化学法和强度法3种。①常规法。分下降式采脂和上升式采脂。下降式采脂是在松树树干2米高处作第一个刮面，开割中沟，再在中沟两侧由上而下陆续开割多数侧沟，流出松脂由中沟导入受脂器。逐年采割至接近地面（图1、图2）。上升式采脂与下降式相反，第一对侧沟配置在刮面的下部，以后由下向上顺次开割。②化学法。用化学药品刺激松树，使其多分泌松脂，延长流脂时间，提高松脂产量和劳动生产率。常用的化学药品有亚硫酸盐酒精醪液和硫酸黑膏等。③强度法。采用加大割面负荷，增开割面，缩短间隔期等办法，适用于伐前1～3年松林。刮皮最好在冬季或早春进行，夏季气温升高，树液流动快，是最好的采脂季节。图2 割面配置松脂加工，中国主要有两种办法：①蒸汽法。先将松脂与适量松节油加热溶解成含油量约达38％的脂液，同时加水洗去有色物质。如脂液的颜色深，需加少量草酸等脱色，经过滤、澄清除去杂质和水分。最后进行间歇式或连续式水蒸气蒸馏，馏出挥发组分冷凝后为松节油。馏余物松香，趁热放出。此法生产的松香质量好，生产安全，适于大、中型工厂。②直接火法。将松脂装入蒸馏锅内，用直接火加热至一定温度后滴入适量清水，水受热成蒸汽将松节油蒸出，最后将锅内松香趁热放出，滤出杂质即为成品。此法简易，适用于就地加工松脂，但产品质量较难控制，生产不太安全。
