保持纸护角水分需要注意什么?

来源:http://www.shuangfengbaozhuang.cn 时间:2021-10-16

1、普通250g/㎡挂面箱纸板水分于8%时,纸护角开始爆裂。
1. When the moisture content of ordinary 250G / ㎡ vermicelli cardboard is lower than 8%, the paper corner guard begins to burst.
2、耐折性能非常好的牛皮箱纸板水分含量于6%时,纸护角纸护角开始爆裂。
2. When the moisture content of kraft linerboard with very good folding resistance is less than 6%, the paper corner protector begins to burst.
3、保持纸板水分对防止纸板爆裂非常重要。
3. Keeping water in the cardboard is very important to prevent the cardboard from bursting.
纸板爆裂的控制办法:
Control method of cardboard bursting:
保持纸护角的水分含量是控制纸板爆裂的办法,从瓦线出来的瓦楞纸水分含量控制在12%--18%之间是比较合理的,由于受一些客观条件的限制,人们往往认为控制纸板水分不太容易。
Keeping the moisture content of the paper corner guard is the way to control the bursting of the paperboard. It is reasonable to control the moisture content of the corrugated paper from the tile line between 12% - 18%. Due to the limitations of some objective conditions, people often think that it is not easy to control the moisture of the paperboard.

测试表明,天气干燥季节,纸板刚从纸板线出来时面纸水分含量在8%左右,有的甚至于6%,瓦楞纸纸护角当纸板堆放四小时后,各层的水分趋于平衡,面纸水分增加到9%以上,因此,若纸板刚从瓦线出来就上机印刷,由于此时面纸水分很,容易导致压线位爆裂,所以纸板生产出来后要堆放足够的时间,到各层的水分平衡后再印刷,纸板面、里水分偏即进行印刷,压线部位会产生微裂,此后,即使面、里水分增加爆线问题也不可能避免。
The test shows that in the dry season, when the paperboard just comes out of the paperboard line, the moisture content of the face paper is about 8%, and some are even lower than 6%. When the paperboard is stacked for four hours, the moisture of each layer tends to balance, and the moisture of the face paper increases to more than 9%. Therefore, if the paperboard is printed on the machine just after coming out of the paperboard line, the moisture content of the face paper is very low, which is easy to lead to the burst of the pressing position, Therefore, after the paperboard is produced, it should be stacked for enough time, and then printed after the water balance of each layer. When the water on the surface and inside of the paper board is low, printing will be carried out, and micro cracks will occur at the pressing part. After that, even if the water on the surface and inside increases, the wire burst problem can not be avoided.
这样既浪费时间也达不到佳的效果避免不了纸板的爆裂,针对此情况,建议在生产过程中使用加湿器进行局部或者整体加湿。这样既避免了堆放导致的时间浪费,也解决了水分偏导致的暴线问题。
This is not only a waste of time, but also can not achieve the best effect, and can not avoid the bursting of paperboard. In view of this situation, it is recommended to use humidifier for local or overall humidification in the production process. This not only avoids the waste of time caused by stacking, but also solves the problem of line burst caused by low moisture.
