济南台历挂历印刷厂家浅谈油墨接皮现象产生的原因

来源:http://www.jindingyinshua.com   日期:2020-05-13

  济南台历挂历印刷厂家在印刷过程中,对油墨的要求是非常高的,主要是因为它决定了印刷的效果,而我们在使用中经常容易出现蒙皮现象,下面就来介绍一下出现这种现象的原因:

  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.油墨粘结剂与空气中的氧气在氧化还原反应中,长时间暴露在空气中当然会发生氧化、结壳现象。
  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.墨辊的结构不好,导致不流动滞留。

  2. The structure of ink roller is not good, resulting in no flow and retention.
  3.如果在墨斗中长时间不搅拌,会出现皮的形成:
  3. If the ink is not stirred for a long time, the skin will form:
  在印刷过程中我们常说的“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动性,然后这样做可以使表面和内部经常交换,避免与空气接触油墨总是相同的部分。
  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.印刷机长时间停机时:
  4. When the printer is shut down for a long time:
  没有清洗墨路,导致墨辊和墨桶的外皮,在工作中一定要注意当停机时间较长时要清洗墨路,当停机时间不是很长时,可以选择在墨路上喷洒防外皮剂。
  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.
  暂时不暴露在空气中放置,过长时间就会出现表面厚厚的氧化膜。我们在印刷厂都有这样的经历,当墨水从墨盒或桶里倒出来的时候。
  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.尽量保持表面平整,原因是尽量减少油墨与空气的接触面积,这样即使在结膜后浪费也会尽可能小。
  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,在剩余部分再盖上一层保护膜,防止与空气接触,也可以防止剥皮现象的发生。
  6. In addition, the remaining part shall be covered with a protective film to prevent contact with air and prevent peeling.
