天气干燥纸箱爆线怎么办?

来源:http://www.shuangfengbaozhuang.cn 时间:2020-03-16

  在冬季干燥的天气里,纸箱生产爆箱的问题困扰着许多纸箱厂家,不仅严重影响了纸箱的质量,损失率急剧上升,而且还会延误发货,使纸箱厂家带来严重的经济损失。通过不断的探索,总结出一些从控制水分到提高爆线的方法,希望对大家有所帮助。
  In the dry weather in winter, the problem of box explosion in the production of cartons perplexes many cartons manufacturers, which not only seriously affects the quality of cartons, but also delays the delivery of goods, causing serious economic losses to cartons manufacturers. Through continuous exploration, summed up some methods from the control of moisture to improve the burst line, hope to help you.
  一、明确:纸箱爆裂的根本原因是什么?
  1、 Clear: what is the root cause of the carton bursting?
  瓦楞纸板的含水率是影响纸箱爆裂的关键因素
  The moisture content of corrugated board is the key factor affecting the bursting of the box
  纸是一种亲水材料,吸水时会变软变硬,失水会变硬变脆。当纸板含水率较低时,水分对瓦楞纸箱爆裂的影响主要表现在两个方面:
  Paper is a kind of hydrophilic material, which will become soft and hard when absorbing water, and hard and brittle when losing water. When the moisture content of cardboard is low, the influence of moisture content on the bursting of corrugated box is mainly manifested in two aspects:
  1. 内纸的耐折性降低,硬纸板的刚度增加,纸箱破裂的可能性增加
  1. The folding resistance of inner paper is reduced, the rigidity of cardboard is increased, and the possibility of carton cracking is increased
  2. 纸板芯的平压强度增加,纸张表面的韧性下降,在压线时容易损坏纸张表面,导致纸箱爆裂。
  2. The flat compression strength of the cardboard core increases, the toughness of the paper surface decreases, and the paper surface is easy to be damaged when pressing the line, resulting in the bursting of the carton.
  二、找到缓解爆线的方法,控制水分是关键
  2、 The key to find a way to relieve the burst line is to control the moisture content
  保持瓦楞纸板的含水率,是控制纸板线条的佳方法。瓦楞纸板的含水率从瓦线控制在12 ~ 18%的范围内,含水率保持在10 ~ 13%的范围内。由于一些客观条件,人们往往认为控制
  Keeping the moisture content of corrugated board is the best way to control the line of board. The moisture content of corrugated board is controlled within 12 ~ 18% from the tile line, and the moisture content is kept within 10 ~ 13%. Because of some objective conditions, people often think that control
  它不容易制造水。在这里,我们将介绍一些更有效的方法:
  It's not easy to make water. Here, we will introduce some more effective methods:
  1. 调整瓦楞纸板的加工工艺
  1. Adjust the processing technology of corrugated board
  传统的瓦楞纸板加工工艺调整方法是有效的。一般来说,我们可以采取以下方法来控制:
  The traditional adjustment method of corrugated board processing technology is effective. Generally speaking, we can take the following measures to control:
  (1)制浆时,适当调整膏体配方,增加膏体含水量。
  (1) During pulping, the paste formula should be adjusted properly to increase the water content of paste.
  (2)增加膏体用量。实践证明,增加糊剂用量能有效提高纸板的含水率,增加糊剂用量也能在一定程度上改善粘接效果。
  (2) Increase the dosage of paste. It has been proved that the increase of paste content can effectively improve the moisture content of paperboard, and the increase of paste content can also improve the bonding effect to a certain extent.

  (3)适当减少原纸与预热轮的接触面积,避免预热筒上的水过度蒸发。
  (3) Properly reduce the contact area between the base paper and the preheating wheel to avoid excessive evaporation of water on the preheating cylinder.
  (4)减少纸板在热板上的停留时间。通过保持高速、缩短热板的长度、降低热板的蒸汽压力等方式避免纸板在热板中通过过度蒸发水分。当使用这种方法时,必须小心确保板不离开坑。
  (4) Reduce the retention time of cardboard on the hot plate. By keeping high speed, shortening the length of the hot plate and reducing the steam pressure of the hot plate, the excessive evaporation of water in the hot plate can be avoided. When using this method, care must be taken to ensure that the plate does not leave the pit.
  2. 纸板制作后应堆放足够的时间后再进行机器打印
  2. The cardboard shall be stacked for enough time before printing
  对纸板从瓦线出来的时间和纸板在机器上印刷的时间之间的水分变化规律缺乏了解是造成爆线的一个重要原因。
  One of the important reasons for the burst is the lack of understanding of the law of moisture change between the time when the paperboard comes out of the tile line and the time when the paperboard is printed on the machine.
  当纸板从瓦片线出来时,虽然整体含水率较高,但每层纸的含水率极不平衡。天气是干燥的季节,纸板刚生产出来时纸板的表面含水量约为8%,有的甚低于6%,当纸板堆放4小时后,每层纸的水分趋于平衡,表面纸的水分增加到9%以上。所以如果纸板刚从瓦楞纸机上打印出来,因为瓦楞纸的表面水分很低,很容易导致压力线爆裂。
  When the paperboard comes out of the tile line, although the overall moisture content is high, the moisture content of each layer of paper is extremely unbalanced. The weather is dry season, when the cardboard is just produced, the surface moisture content of the cardboard is about 8%, some even lower than 6%. When the cardboard is stacked for 4 hours, the moisture content of each layer of paper tends to balance, and the moisture content of the surface paper increases to more than 9%. So if the paperboard is just printed out of the corrugating machine, because the surface moisture of the corrugating paper is very low, it is easy to cause the pressure line to burst.
  改进方法:
  Improvement method:
  1. 纸板生产后应堆放足够的时间,待每层纸的水分达到平衡后,将其打印在机器上。如果纸板和衬纸的含水量较低,它就会印在线条上,线条就会微微开裂,那么即使表面和衬纸的含水量增加,线条爆炸的问题也是无法避免的。
  1. The paperboard shall be stacked for enough time after production, and printed on the machine after the moisture of each layer of paper reaches the balance. If the moisture content of paperboard and liner is low, it will be printed on the line, and the line will slightly crack, so even if the moisture content of the surface and liner increases, the problem of line explosion is inevitable.
  2. 如果发货时间太短,没有足够的时间使纸板水分平衡,湿水到纸板表面是直接有效的方法。潮湿的水好避免影响印刷现场,否则会对印刷造成不利影响。如果条件允许,可以使用磨损的野外版
  2. If the delivery time is too short and there is not enough time to make the water balance of the cardboard, wet water to the cardboard surface is the most direct and effective method. Wet water is best to avoid affecting the printing site, otherwise it will cause adverse effects on printing. If conditions permit, a worn field version can be used
  要制做湿版,先用印台把线打湿,然后再打印。这样,可以快速的将生产线压湿,而且不影响印刷质量。
  To make a wet plate, first wet the line with the printer, and then print. In this way, the production line can be quickly pressed wet, and does not affect the printing quality.
