冬季纸箱胶水怎样才能正常使用?

来源:http://www.shuangfengbaozhuang.cn 时间:2021-11-11

冬天气候寒冷,气温或多或少会对一些重型纸箱的制作产生影响,比如说瓦楞纸箱中胶水的使用,胶水会因为冬季的气温过而发生冻结的情况,那么您知道有什么方法可以让胶水在气温的情况下正常使用呢
一、缩短涂胶后至纸箱贴合之间的时间。(例平常印刷纸箱厂制品涂胶2米长,秋冬季应涂1米左右,注意不要等纸箱印刷品所涂胶面的胶层凉干后再压合,一定要确保纸箱粘合剂对粘合面的充分浸润,避免开胶)。
The cold weather and low temperature in winter will more or less affect the production of some heavy cartons. For example, the use of glue in corrugated cartons will freeze due to the low temperature in winter. Do you know what methods can make the glue work normally under low temperature? First, shorten the time between gluing and carton fitting. (for example, the products of carton printing factory are usually coated with glue for 2 meters, and about 1 meter should be coated in autumn and winter. Be careful not to wait for the adhesive layer on the coated surface of carton printing to dry before pressing. Be sure to ensure that the adhesive of carton is fully soaked on the adhesive surface to avoid glue opening).

二、纸箱粘合后增大压合力和延长压合时间或用柔软布料用力来回擦拭,以免纸箱开口或起泡现象。
2、 After the carton is bonded, increase the pressing force and prolong the pressing time, or wipe it back and forth with soft cloth to avoid carton opening or blistering.
三、由于近年来纸箱厂胶水发展较快,其纸箱胶水配方千变万化,纸箱胶水中的增塑剂,增滑剂,防水防潮剂等助剂迁移。会导致纸箱制盒时使粘接强度的下降,甚至破坏粘接胶层,因此一般过有光胶,哑胶纸箱印刷品采用本纸箱胶水8828、8321PP胶,对磨光、白板、铜板面采用8822、8802型纸箱粘合剂。
3、 Due to the rapid development of glue in carton factory in recent years, the formula of carton glue is ever-changing, and the additives such as plasticizer, sliding agent, waterproof and moisture-proof agent in carton glue migrate. It will reduce the bonding strength and even damage the bonding adhesive layer when making cartons. Therefore, there is usually too much gloss adhesive. The carton glue 8828 and 8321pp adhesive are used for dumb adhesive carton printing, and 8822 and 8802 carton adhesives are used for polishing, whiteboard and copper plate.
四、针对挺度较大的纸箱厂产品,为了让纸箱两被粘面充分接触要施压半小时,以免纸箱粘合后产品自动弹开。
4、 For carton factory products with large stiffness, in order to make full contact between the two bonded surfaces of the carton, it is necessary to apply pressure for half an hour to prevent the product from springing open automatically after the carton is bonded.
