How to distinguish the quality of book binding glue? The hot melt adhesive used in books is divided into backing adhesive and edge sealing adhesive According to the thickness of different materials of paper and books, book adhesives with different viscosities and flow effects can be used to complete the bonding work of book pages.
Hot melt adhesive for books is already very mature, and both thick and thin books can be glued together. However, many people do not pay much attention to the application of hot melt adhesive in their daily lives.
How to distinguish book binding hot melt adhesive:
Firstly, the same paper can be used and different machine speeds can be used to test the glue. Through this testing method, the bonding effect and tensile strength of this hot melt adhesive can be determined. On the same machine, test the bonding effect and tensile strength of this hot melt adhesive with different papers at the same speed. Put the glued paper in the refrigerator and freeze for about 1-3 hours. Take out the paper in batches, separate the glue from the middle, observe whether the paper is damaged or brittle, and determine the weather resistance of the glue. Of course, for book hot melt adhesive itself, it is necessary to observe whether the adhesive has impurities, whether there are bubbles, and the viscosity of the adhesive during heating to determine the quality of the adhesive.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: 1、 Understand and master the models and technical performance (including technical parameters) of each EVA hot melt adhesive. Different types of hot melt adhesives have different opening and curing times. […]
Hot melt adhesive granulesCan PET film be adhered? Yes, but it depends on the particle type and usage method. PET (polyethylene terephthalate) film has low surface energy and weak polarity, and ordinary EVA hot melt adhesive particles are prone to “false adhesion” and easy to peel off when directly adhered. To firmly adhere PET, a […]
When manufacturers have to deal with coke, valuable production time is wasted. Therefore, it is important to understand the reasons for the carbonization of EVA hot melt adhesive and how to prevent it as much as possible. Hot melt adhesive carbonizes in the sink Charcoal is composed of combustion particles produced by the thermal degradation […]
It’s not that difficult to change the glue for the glue installation machine in the graphic store Many graphic and text store owners are afraid of changinghot melt adhesive pellets——Afraid of blocking rubber hoses, afraid of temperature switching problems, and afraid of wasting glue. In fact, as long as you follow the steps, it can […]
