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.What are the properties, costs, and functions of hot melt adhesive? Many different materials are used to produce different hot melt adhesives. The final performance of hot melt adhesive indicates that there are significant differences in the cost, performance, and functionality of the final product of hot melt adhesive. Tape and label hot melt adhesive […]
1. Polymer Matrix The main components of EVA hot melt adhesive play a crucial role in its performance. Main types: ethylene and its copolymers, polyolefins, polyesters, polyurethanes, polyamides, styrene and its block copolymers, and other polymers. The impact on the properties of hot melt adhesive: adhesive strength, melt index, softening point, viscosity, flexibility, curing speed, […]
EVA hot melt adhesive is a new type of adhesive developed to meet the requirements of being harmless, energy-saving, resource-saving, and environmentally friendly today. The characteristic of EVA hot melt adhesive is that it is 100% solid and does not contain water or other solvents, so there is no environmental pollution or residual solvent toxicity […]
More and more manufacturers are using EVA hot melt adhesive to process books and other materials, regardless of the size of the processing plant, there will still be an upward trend in the future. This is because using this adhesive has the advantages of fast book publishing, short cycle time, beautiful appearance of books, and […]
