EVA hot melt adhesive is different from regular cold melt adhesive. According to its characteristics, the following points must be mastered and noted during use:
When using EVA hot melt adhesive, do not heat it directly with an open flame. Be sure to heat with isolation oil (the boiling point of water should reach 100 ℃) or use a sealed electric heating plate. Before using solid EVA hot melt adhesive, it must be preheated with a preheating device and then released into the working glue box of the adhesive. The preheating time is generally around 2 hours. When using glue, do not directly mix solid glue blocks (i.e. glue that has not been preheated) into the glue box to prevent Poor fluidity of glue or applying partially melted glue on the back of the book, resulting in uneven application of glue. The amount of glue in the preheated glue pot should be controlled properly. If too much is used, the glue will melt one by one, causing deterioration and aging, reducing viscosity, and affecting adhesion. The entire bonding process must be completed within the opening time of the hot melt adhesive. If the machine is stopped due to a malfunction, the books in the bookshelf must be removed in a timely manner, and the book core must not stay above the glue wheel. When repairing wireless adhesive binding equipment for a long time, the pre coating glue and working glue pot should be turned off to prevent glue aging. The temperature of the molten colloid should be strictly controlled within the range of use. How can EVA hot melt adhesive improve the safety of boxes and cartons? In addition to increasing production line speed to meet greater packaging demands, many box and carton factories hope to improve worker safety. Although this may require ensuring the use of appropriate hot melt adhesive at all times, the correct adhesive can have […]
What issues should be considered when using EVA hot melt adhesive? Although there are various types of hot melt adhesives, there are five key factors that can affect their performance. Consider these items before applying hot melt adhesive to ensure ideal performance: Temperature When using EVA hot melt adhesive, ensure that it can fully wet […]
How to avoid equipment failure caused by carbonization of EVA hot melt adhesive? The carbonization of hot melt adhesive in the hot melt tank is left unattended, which can damage your equipment, have a negative impact on your factory’s productivity, and cause unnecessary downtime. Follow these simple tips to reduce hot melt adhesive carbonization and […]
What are the environmentally friendly adhesives? Adhesive is any substance that binds two objects together – essentially glue. The objects adhered together by our adhesive are considered as “substrates”. Have you ever made a grilled cheese sandwich? Once melted and cooled, cheese can be considered as a binder that binds two slices of bread (substrate) […]
