济南印刷厂温渡过高产生了油墨结皮怎么办

来源:http://www.jindingyinshua.com   日期:2019-10-09

  很多印刷厂在印刷过程中,由于很多设备和环境问题,所以室内温度会比较高,这就会导致油墨剥皮的现象,下面就给大家分析一下油墨剥皮温度过高的原因:

  Many printing plants in the printing process, due to a lot of equipment and environmental problems, so the indoor temperature will be relatively high, which will lead to the phenomenon of ink peeling, the following will give you an analysis of the reasons for the high temperature of ink peeling:
  一、引起油墨结壳温度过高,主要引起高温。当油墨温度过高时,不饱和分子的活性增加,特别是表面空气与结膜部分的氧化作用中的氧气。
  First, the temperature of ink crust is too high, which mainly causes high temperature. When the ink temperature is too high, the activity of unsaturated molecules increases, especially the oxygen in the oxidation between surface air and conjunctiva.
  二、高温的几个方面:
  2. Several aspects of high temperature:
  1、机器其它异常温升引起。
  1. Other abnormal temperature rise of the machine.
  2、空气从烘干机中漏出使油墨表面干燥,或热空气进入墨斗造成。
  2. Air leaks from the dryer to dry the ink surface, or hot air enters the ink bucket.
  3、环境温度过高:一般夏季油墨剥皮现象比冬季明显得多,如果车间内没有空调时性能更明显。合理控制工作环境的温度是必要的。

  3. The ambient temperature is too high: In general, the phenomenon of ink peeling in summer is much more obvious than in winter. If there is no air conditioning in the workshop, the performance 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也会使油墨在印刷过程中:
  4. When the temperature on the machine is too high, it will also make the ink in the printing process:
  (1)当墨辊之间的接触压力过大时,温升更显着,这时油墨很容易出现在墨辊和墨辊剥皮的现象。
  (1) When the contact pressure between ink rollers is too high, the temperature rise is more significant. At this time, ink can easily appear in the phenomenon of peeling between ink rollers and ink rollers.
  (2)准确调节和控制油墨辊间的压力,对防止油墨在印刷过程中产生影响具有十分重要的意义。
  (2) It is of great significance to accurately regulate and control the pressure between ink rollers in order to prevent the influence of ink in the printing process.
  (3)一般来说,车间温度控制在20℃左右比较理想,即保证油墨良好的流动性和转移性能,而油墨结壳控制在一个相对较低的程度。
  (3) Generally speaking, the workshop temperature control is ideal at about 20 C, that is, to ensure good fluidity and transfer performance of ink, while the ink crust control is at a relatively low level.
  三、油墨干性油含量过高:
  3. Excessive dry oil content in ink:
  一般在制作油墨或印刷过程中都会出现这样的错误。添加干燥剂时必须结合印刷条件和环境温度进行适当的添加。
  Such errors usually occur in the process of making ink or printing. When adding desiccant, it must be combined with printing conditions and ambient temperature for proper addition.
  在印刷时,有很多因素会导致油墨脱皮,而高温是常见的因素之一,所以在未来的印刷中,我们的员工应该合理控制室内温度,保持室温,减少不必要的麻烦。
  In printing, there are many factors leading to ink peeling, and high temperature is one of the common factors, so in future printing, our staff should reasonably control the indoor temperature, maintain room temperature, reduce unnecessary trouble.
