很多印刷廠在印刷過程中,由于很多設備和環境問題,所以室內溫度會比較高,這就會導致油墨剝皮的現象,下面就給大家分析一下油墨剝皮溫度過高的原因:
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、引起油墨結殼溫度過高,主要引起高溫。當油墨溫度過高時,不飽和分子的活性增加,特別是表面空氣與結膜部分的氧化作用中的氧氣。
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、高溫的幾個方面:
2. Several aspects of high temperature:
1、機器其它異常溫升引起。
1. Other abnormal temperature rise of the machine.
2、空氣從烘干機中漏出使油墨表面干燥,或熱空氣進入墨斗造成。
2. Air leaks from the dryer to dry the ink surface, or hot air enters the ink bucket.
3、環境溫度過高:一般夏季油墨剝皮現象比冬季明顯得多,如果車間內沒有空調時性能更明顯。合理控制工作環境的溫度是必要的。
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、當機器上的溫度過高時也會使油墨在印刷過程中:
4. When the temperature on the machine is too high, it will also make the ink in the printing process:
(1)當墨輥之間的接觸壓力過大時,溫升更顯著,這時油墨很容易出現在墨輥和墨輥剝皮的現象。
(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)準確調節和控制油墨輥間的壓力,對防止油墨在印刷過程中產生影響具有十分重要的意義。
(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)一般來說,車間溫度控制在20℃左右比較理想,即保證油墨良好的流動性和轉移性能,而油墨結殼控制在一個相對較低的程度。
(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、油墨干性油含量過高:
3. Excessive dry oil content in ink:
一般在制作油墨或印刷過程中都會出現這樣的錯誤。添加干燥劑時必須結合印刷條件和環境溫度進行適當的添加。
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.
在印刷時,有很多因素會導致油墨脫皮,而高溫是常見的因素之一,所以在未來的印刷中,我們的員工應該合理控制室內溫度,保持室溫,減少不必要的麻煩。
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.
