冬天氣候寒冷，氣溫或多或少會對一些重型紙箱的制作產(chǎn)生影響，比如說瓦楞紙箱中膠水的使用，膠水會因為冬季的氣溫過而發(fā)生凍結(jié)的情況，那么您知道有什么方法可以讓膠水在氣溫的情況下正常使用呢
一、縮短涂膠后紙箱貼合之間的時間。(例平常印刷紙箱廠制品涂膠2米長，秋冬季應(yīng)涂1米左右，注意不要等紙箱印刷品所涂膠面的膠層涼干后再壓合，一定要確保紙箱粘合劑對粘合面的充分浸潤，避免開膠)。
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、紙箱粘合后增大壓合力和延長壓合時間或用柔軟布料用力來回擦拭，以免紙箱開口或起泡現(xiàn)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、由于近年來紙箱廠膠水發(fā)展較快，其紙箱膠水配方千變?nèi)f化，紙箱膠水中的增塑劑，增滑劑，防水防潮劑等助劑遷移。會導(dǎo)致紙箱制盒時使粘接強度的下降，甚破壞粘接膠層，因此一般過有光膠，啞膠紙箱印刷品采用本紙箱膠水8828、8321PP膠，對磨光、白板、銅板面采用8822、8802型紙箱粘合劑。
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、針對挺度較大的紙箱廠產(chǎn)品，為了讓紙箱兩被粘面充分接觸要施壓半小時，以免紙箱粘合后產(chǎn)品自動彈開。
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.
