在生产过程中会遇到一个头疼问题,就是针对塌箱和粘箱机粘不牢问题,小编总结给出解决方案是改善纸板材质,提高抗压强度及防潮性能,从而减少塌箱率。另外还一点需要提高粘合强度,增加淀粉糊的固含量,通过降上胶量提高纸板硬度解决粘箱机粘不牢问题。
In the production process, we will encounter a headache, that is, aiming at the problem of collapsing and sticking machine not sticking firmly, Xiaobian summed up the solution is to improve the cardboard material, improve the compressive strength and moisture-proof performance, so as to reduce the collapsing rate. In addition, we need to improve the adhesive strength, increase the solid content of starch paste, and improve the hardness of paperboard by reducing the amount of glue, so as to solve the problem that the box gluing machine can not stick firmly.
包装厂如何应对粘箱机粘不牢塌箱问题生产使用应注意以下几点:
How to deal with the problem that the gluing machine can't stick firmly and the box collapses? The following points should be paid attention to in production and use:
1、要控制好原纸的使用
1. To 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 condition of corrugated paper, water absorption index of base paper surface. 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、生产纸板时要控制纸板的水分含量
2. The moisture content of paperboard should be controlled when producing paperboard
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 the paperboard should not be too much, because the hardness of the paperboard is low when the moisture content is large, which affects the edge pressure index of the paperboard. In the process of paperboard processing, the amount of glue on the single-sided machine and double-sided machine should not be too large. Once the amount of glue is large, the corrugated shape of the paperboard will be deformed, and the shape of corrugated directly affects the edge pressure of the paperboard. When the edge pressure decreases, the compressive strength of the paperboard will also decrease.
3、纸板的粘合强度要大
3. The adhesive strength of paperboard should be high
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 of corrugated paper with inner paper and face paper. If in case of false sticky paperboard, after pressure, face paper or liner paper will be separated from corrugated paper, then the compressive strength will decline.
4、生产环节中的间隙压力控制要适中
4. The gap pressure control in the production process should be moderate
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, pay attention to paste the gap pressure on the box pasting machine can not be too small, double-sided machine, die-cutting machine on the sun wheel gap pressure to be controlled in a reasonable range, in order to avoid corrugating crush, affect the compressive strength of the paperboard.
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, waterproof varnish, etc. to solve the surface waterproof and moisture-proof problems.
