油墨剥落温度过高的原因

很多印刷厂在印刷过程中,由于设备和环境问题很多,所以室内温度会比较高,这就会导致油墨剥落现象,下面分析一下油墨剥落温度过高的原因:

In the printing process of many printing factories, due to a lot of equipment and environmental problems, the indoor temperature will be relatively high, which will lead to ink peeling phenomenon. The following is an analysis of the reasons why the ink peeling temperature is too high:

首先,引起油墨结壳温度过高,是引起高温的主要原因。当油墨温度过高时,不饱和分子的活性增加,尤其是表面空气和结膜中的氧气的氧化。

First of all, causing ink crust temperature is too high, is the main cause of high temperature. When the ink temperature is too high, the activity of unsaturated molecules increases, especially the oxidation of surface air and oxygen in the conjunctiva.

二世。高温方面:

II. High temperature:

1、机器引起的其他异常温升。

1. Other abnormal temperature rise caused by the machine.

2、空气从烘干机中干燥油墨表面,或热空气进入墨斗造成。

2. Air from the dryer to dry the ink surface, or hot air into the ink.

3、环境温度过高:一般夏季油墨剥落现象要比冬季明显得多,如果车间内没有空调性能更明显。合理控制工作环境的温度是必要的。

3. Environment temperature is too high: generally, the phenomenon of ink peeling in summer is much more obvious than in winter, if there is no air conditioning performance in the workshop, it is more obvious. It is necessary to control the temperature of working environment reasonably.

4. 当机器上的温度过高时,油墨在印刷过程中也会用到:

4. When the temperature on the machine is too high, the ink will also be used in the printing process:

(1)当辊间接触压力较大时,温升比较明显,这时油墨很容易在辊内出现剥落现象。

(1) When the contact pressure between the rollers is large, the temperature rise is obvious, and the ink is easy to peel off in the roller.

(2)准确调节和控制墨辊之间的压力,对防止油墨在印刷过程中的影响具有十分重要的意义。

(2) It is very important to adjust and control the pressure between ink rollers accurately to prevent the influence of ink in the printing process.

(3)一般来说,车间温度控制在20℃是比较理想的,即保证油墨良好的流动性和转移性能,油墨结壳控制在一个相对较低的程度。

(3) Generally speaking, it is ideal to control the workshop temperature at 20 ℃, that is, to ensure the good fluidity and transfer performance of the ink, and to control the ink crust at a relatively low level.

三、油墨干性油含量过高:

3、 Ink dry oil content is too high:

一般在生产油墨或印刷过程中都会出现这样的误差。干燥剂的添加必须与印刷条件和环境温度相结合,才能进行适当的添加。

Generally in the production of ink or printing process will appear such errors. The addition of desiccant must be combined with printing conditions and ambient temperature in order to add properly.

在印刷过程中,有很多因素会导致油墨剥落,而高温是其中一个常见的因素,所以在未来的印刷中,我们的工作人员应该合理控制室温,保持室温,减少不必要的麻烦。

In the printing process, there are many factors that will lead to ink peeling, and high temperature is one of the common factors, so in the future printing, our staff should reasonably control the room temperature, keep the room temperature, and reduce unnecessary troubles.
