在制造以松香作为基本原料的甘油酯、松香改性马来酸树脂和松香改性酚醛树脂时,都把松香在高温下经一定时间进行加热处理(即松香的热处理),就会得到常见的浅色树脂,这是使用松香的人常常使用的方法。但是,关于这个热处理动力学的探讨的报告,基本上还未见到。笔者根据以往的实践经验的方法,从动力学观点分析,探讨松香热处理中变化的一个方面,现介绍如下。
In the production of rosin as the basic raw material of glycerol, rosin-modified maleic acid resin and rosin-modified phenolic resin, rosin at a high temperature for some time after heat treatment (ie rosin heat treatment), you will get a common Light-colored resin, which is often used by people who use rosin. However, the report on the discussion of this heat treatment kinetics has basically not been seen. The author based on past practice and methods of experience, from the dynamic point of view to explore the changes in the rosin heat treatment in one aspect, are presented below.
