怎样应对纸箱粘不牢而塌箱的问题

来源:http://www.shuangfengbaozhuang.cn 时间:2022-02-10

据调查显示,纸箱是目前使用多流通广的包装产品。然而,它在生产中偶尔也会遇到塌箱和粘不牢的问题。那么,这些问题该如何应对呢?来看看烟台纸箱厂家给出的相关解决办法:
According to the survey, cartons are widely used and widely circulated packaging products. However, it occasionally encounters the problems of box collapse and weak adhesion in production. So, how to deal with these problems? Let's take a look at the relevant solutions given by Yantai carton manufacturer:
1、要控制好原纸的使用
1. Control the use of base paper
检查瓦楞纸的施胶情况,原纸表面吸水性指标药效。如果原纸表面施胶差,吸水性就会偏高,很容易手冷库温、潮湿的环境影响,导致回潮,变软,整理抗压强度降。
Check the sizing of corrugated paper, water absorption index of base paper surface and efficacy. If the surface sizing of base paper is poor, the water absorption will be on the high side. It is easy to be affected by the low temperature and humid environment of hand cold storage, resulting in moisture regain, softening and reduction of finishing compressive strength.
2、生产环节中的间隙压力控制要适中
2. The gap pressure in the production process should be controlled moderately
尤其要注意糊箱机上糊的间隙压力不能太小,双面机,模切机上的太阳轮间隙压力要控制在合理的范围内,以避免将瓦楞形压溃,影响纸板的抗压强度。
In particular, it should be noted that the gap pressure of the paste on the box pasting machine should not be too small. The gap pressure of the sun wheel on the double-sided machine and die-cutting machine should be controlled within a reasonable range to avoid crushing the corrugated shape and affecting the compressive strength of the paperboard.
3、生产纸板时要控制纸板的水分含量
3. When producing paperboard, the moisture content of paperboard should be controlled
纸板的水分含量不可过多,因为水分大则纸板的硬度,影响纸板的边压指数。在纸板加工过程中,单面机和双面机工序上胶量不能过大。一旦上胶量大,纸板的楞形会变形,而瓦楞的形状是直接影响纸板的边压的,边压降,的抗压强度也随之降。
The moisture content of paperboard should not be too much, because if the moisture is large, the hardness of paperboard is low, which affects the edge pressure index of paperboard. In the process of paperboard processing, the glue amount of single-sided machine and double-sided machine process shall not be too large. Once the amount of glue is large, the corrugated shape of the paperboard will be deformed, and the corrugated shape will directly affect the edge pressure of the paperboard. If the edge pressure is reduced, the compressive strength of the paperboard will also be reduced.
4、纸板的粘合强度要大
4. The adhesive strength of paperboard should be large
粘合强度是瓦楞纸与里纸、面纸的粘合力。如果万一出现纸板假粘,受压后,面纸或里纸便会与瓦楞纸分离,那么的抗压强度会直线下降。
Adhesion strength is the adhesion between corrugated paper and lining paper and face paper. In case of false sticking of paperboard, the face paper or inner paper will be separated from the corrugated paper after being pressed, and the compressive strength of the paperboard will decrease linearly.
5、使用泼水剂、防水光油等解决表面防水防潮问题。
5. Use water splashing agent and waterproof varnish to solve the problem of surface waterproof and moisture-proof.
