印刷包装时有堵版故障出现怎么回事?

来源:http://www.xinfengyinshua.cn/   发布时间:2022-04-18
  印刷包装时总会有很多问题出现,所以就需要提前做好预防工作,以免给工作造成大的损失。今天我们就来说一说印刷包装时的堵版故障的原因是什么。
  There are always many problems in printing and packaging, so it is necessary to do preventive work in advance, so as not to cause big losses to the work. Today we say what is the cause of the blocking of printing and packaging.
  由于某些因素(例如溶剂挥发过快),留在单元格中的墨水会部分干燥和凝固。当印版滚筒再次进入墨槽时,网穴中已固化的油墨难以完全溶解,油墨转移率也随之提高。累积效应是细胞被越来越浅地阻塞,直到发生阻塞失败。这种堵塞故障与油墨种类、粘度、干燥速度、溶剂种类、印刷速度、印刷机结构等因素有关,其中比较常见的有以下两种原因。
  Due to certain factors, such as the rapid evaporation of the solvent, the ink left in the cell will partially dry and solidify. When the printing plate cylinder again into the ink tank, the net hole has been solidified ink is difficult to completely dissolve, ink transfer rate also increases. The cumulative effect is that the cells become shallower and shallower until the blockage fails. This blockage failure is related to the type of ink, viscosity, drying speed, solvent type, printing speed, printing machine structure and other factors, among which the following two reasons are more common.
  油墨干燥速度。当油墨干燥过快时,一部分油墨在转移到承印材料上之前会形成一层薄膜,而油墨薄膜的溶解性差必然导致油墨转移不良,经过一段时间的积累,印刷盘子会被挡住。印刷车间的温度和湿度会影响油墨的干燥速度。温度过高或湿度过低都会加快油墨的干燥速度。如果墨水循环不良,墨水盒中的墨水很容易形成薄膜,从而导致堵塞。
  Ink drying speed. When the ink dries too fast, part of the ink will form a film before transferring to the substrate, and the poor solubility of the ink film will inevitably lead to poor ink transfer, after a period of accumulation, the printing plate will be blocked. The temperature and humidity of the printing shop will affect the drying rate of ink. High temperature or low humidity will accelerate the drying speed of ink. If the ink circulates poorly, the ink in the cartridge can easily form a thin film, which can lead to blockage.
  凹印设备问题。如果凹版印刷设备的各种机构设计存在问题,如滚筒直径大、印版滚筒在墨槽中浸入较浅等,干燥时漏出的热风盒子会直接吹到印版版面上,这会导致油墨在网版上在孔内干燥。
  Gravure printing equipment problems. If there are problems in the design of various mechanisms of gravure printing equipment, such as large diameter of the drum, shallow immersion of the plate drum in the ink tank, etc., the hot air box leaked during drying will be directly blown to the plate layout, which will lead to ink drying in the hole on the screen.
  山东印刷包装认为杂质从外部环境混入墨水中。凹版印刷速度快,高速运转时承印物容易产生静电。在静电吸附的作用下,可能会将周围环境中的灰尘和从承印物上脱落的碎屑等杂质带入油墨中。
  Shandong printing and packaging that impurities from the external environment mixed with ink. Gravure printing is fast and the substrate is easy to produce static electricity when running at high speed. Under the action of electrostatic adsorption, it may bring the dust in the surrounding environment and impurities such as debris off the substrate into the ink. Plate cell blockage is an important reason.
  为防止此类事故的发生,应在循环泵吸嘴处使用滤网除去油墨中的不溶性杂质。凹版印刷网线数较多时,油墨中较大的颗粒、不溶性物质和沉淀物会造成印版网孔堵塞。当油墨本身发生颜料分离、沉淀、重新凝聚等变化时,会产生不易重新溶解的物质,造成堵塞。
  In order to prevent the occurrence of such accidents, the circulating pump suction nozzle should be used to remove insoluble impurities in the ink. Intaglio printing more network lines, ink in the larger particles, insoluble substances and sediments will cause plate mesh blockage. When the ink itself pigment separation, precipitation, re - coagulation and other changes, will not easily re - dissolved substances, resulting in blockage.
