濟南台曆掛曆印刷廠家淺談油墨接皮現象產生的原因

來源:http://www.jnurs.com   日期:2020-05-13

  濟南台曆掛曆印刷廠家在印刷過程中,對油墨的要求是非常高的,主要是因為它決定了印刷的效果,而我們在使用中經常容易出現蒙皮現象,下麵就來介紹一下出現這種現象的原因:

  In the printing process of Jinan calendar printing factory, the ink requirements are very high, mainly because it determines the printing effect, and we are often prone to skin phenomenon in use. Here are the reasons for this phenomenon:
  1.油墨粘結劑與空氣中的氧氣在氧化還原反應中,長時間暴露在空氣中當然會發生氧化、結殼現象。
  1. In the oxidation-reduction reaction between the ink binder and the oxygen in the air, the phenomenon of oxidation and crusting will certainly occur when exposed to the air for a long time.
  2.墨輥的結構不好,導致不流動滯留。

  2. The structure of ink roller is not good, resulting in no flow and retention.
  3.如果在墨鬥中長時間不攪拌,會出現皮的形成:
  3. If the ink is not stirred for a long time, the skin will form:
  在印刷過程中我們常說的“三常”墨水是非常重要的,它可以保持油墨墨墨墨是非常好的流動性,然後這樣做可以使表麵和內部經常交換,避免與空氣接觸油墨總是相同的部分。
  In the printing process, we often say that the "three constant" ink is very important. It can keep the ink and ink very good fluidity, and then it can make the surface and interior exchange frequently, avoiding the same part of the ink that is always in contact with the air.
  4.印刷機長時間停機時:
  4. When the printer is shut down for a long time:
  沒有清洗墨路,導致墨輥和墨桶的外皮,在工作中一定要注意當停機時間較長時要清洗墨路,當停機時間不是很長時,可以選擇在墨路上噴灑防外皮劑。
  If the ink path is not cleaned, resulting in the outer skin of the ink roller and the ink barrel, it must be noted that the ink path must be cleaned when the downtime is long. When the downtime is not long, you can choose to spray the anti skin agent on the ink path.
  暫時不暴露在空氣中放置,過長時間就會出現表麵厚厚的氧化膜。我們在印刷廠都有這樣的經曆,當墨水從墨盒或桶裏倒出來的時候。
  If it is not exposed to air for a while, a thick oxide film will appear on the surface for a long time. We all have this experience in printing houses when ink comes out of ink cartridges or barrels.
  5.盡量保持表麵平整,原因是盡量減少油墨與空氣的接觸麵積,這樣即使在結膜後浪費也會盡可能小。
  5. Try to keep the surface flat, because the contact area between ink and air is minimized, so that the waste will be as small as possible even after conjunctiva.
  6.另外,在剩餘部分再蓋上一層保護膜,防止與空氣接觸,也可以防止剝皮現象的發生。
  6. In addition, the remaining part shall be covered with a protective film to prevent contact with air and prevent peeling.
