马尾松树脂沉积的评价方法与影响因素

Method Evaluating Deposition Potential of Mason Pine Pitch and Some Related Affecting Factors

介绍了一种实验室树脂沉积潜力评价方法———旋转搅拌法。利用该方法对马尾松树脂沉积特性进行了研究 ,发现金属离子、pH值、温度、气泡的混入和时间等因素对树脂沉积都有重要影响。

An effective method called rotating-mixer, which can evaluates the deposition potential of wood resin in laboratory, is presented. Taking Mason pine resin as an example, some factors leading to resin deposition are also studied. The experiments results show that decrease of pH, existence of metal ions, shock of temperature and introduction of air bubbles are important reasons resulting in resin destabilization and deposition.
