环境温度和模切刀精度对热熔胶不干胶材料模切的影响
作者:admin 来源:http://www.sdhzyw.com 发布时间:2019-7-11 15:48:16 浏览次数:338
印刷厂家应该都遇到过热熔胶不干胶材料模切方面的问题:模切后排废时出现不规则掉标现象,而现场同时使用的另一家供应商的不干胶材料,也是热熔胶的材料,却模切正常,没有出现排废掉标现象。济南宣传单页印刷记录下这种想象发生的原因与大家一起分享,希望可以帮到大家!
Printers should all encounter problems in die-cutting of superheated melt adhesives: irregular off-label phenomenon occurs when waste is discharged after die-cutting, while dry adhesives from another supplier are also hot-melt adhesives used at the same time, but die-cutting is normal and there is no phenomenon of discharging off-label. Jinan promotional leaflet printing records the reasons for this imagination to share with you, I hope to help you!
1.黏度
1. Viscosity
由于不干胶材料涂胶量大,模切就困难,出现问题的几率就大。
Because of the large amount of glue on the adhesive material, die cutting is difficult and the probability of problems is high.
2.剂种类
2. Category of agents
不同的黏合剂,成分不一样,内应力不同,模切特性也会不一样。一些高档的热熔胶材料,模切特性接近乳剂胶(水胶),基本没有模切问题;而一些低档、便宜的热熔胶材料,模切经常出现问题。

Different adhesives have different compositions, different internal stresses and different die-cutting characteristics. Some high-grade hot-melt adhesives have similar die-cutting characteristics to latex (hydrogel), and there are no die-cutting problems. However, some low-grade and cheap hot-melt adhesives often have problems in die-cutting.

3.厚度
3. Thickness
模切刀的尺寸精度是根据底纸的厚度确定的,所以,底纸的厚度决定了模切的精度。
The dimension accuracy of die cutter is determined by the thickness of base paper, so the thickness of base paper determines the accuracy of die cutting.
4.温度
4. Temperature
当车间温度为8℃时,模切掉标明显,浪费很大;当温度上升到16℃时,模切掉标现象明显改善,但仍有10%~20%的掉标。这种现象说明模切掉标同温度有关,同环境条件有关。
When the workshop temperature is 8 C, the standard-cutting is obvious and wasteful; when the temperature rises to 16 C, the phenomenon of standard-cutting is obviously improved, but there are still 10%-20% of the standard-dropping. This phenomenon shows that die cutting standard is related to temperature and environmental conditions.
5.刀精度
5. Knife Accuracy
模切时掉标说明黏合剂层存在没有完全切透、切断的地方,黏合剂没有切透是造成掉标的原因之一。由于模切刀辊是走肩铁的,不能大幅度调整,只能微调,在模切压力已到更大这种状态下,模切装置只能更换新的模切刀片,才能解决黏合剂不能完全切透的问题。
Label dropping during die cutting indicates that there is a place where the adhesive layer is not completely cut through and cut off. Lack of cutting through of the adhesive is one of the reasons for the mark dropping. Because the die cutter roll is shoulder iron, it can not be adjusted by a large margin, and can only be fine-tuned. Under the condition that the die cutting pressure has reached its maximum, the die cutting device can only replace the new die cutter blade to solve the problem that the adhesive can not be completely cut through.
