松香是工业的重要原料,又是我国出口物资。为了发展松香生产,解决松香生产上存在的结晶问题,我们调查了一些松香厂(蒸汽法厂6个,滴水法厂7个),通过学习,总结了一些防止松香结晶的方法,现简述如下: 一、引起松香结晶的因素引起松香结晶的原因直到目前为止还不十分清楚。在福建,一般认为,引起松香结晶的因素有以下几种: 1.高温引起结晶。主要是因为操作温度过高或煮炼时间过长,产生大量的晶种,因而形成结晶。这种结晶形状是星状、丝发状或砂 Rosin is an important raw material for industry, but also our country’s exports. In order to develop rosin production and solve the problem of crystallization in rosin production, we investigated some rosin plants (6 steam plants and 7 dripping plants). After studying, some methods to prevent rosin crystallization were summarized as follows : First, the factors that cause the crystallization of rosin Cause of rosin crystallization so far not yet very clear. In Fujian, generally believed that the factors that cause rosin crystallization are the following: 1. High temperature caused by crystallization. Mainly because of the operating temperature is too high or cooking time is too long, resulting in a large number of seeds, thus forming the crystallization. This crystalline shape is a star, silk or sand
