What hot melt adhesive is used for book binding? Nowadays, EVA type hot melt adhesive is commonly used to stick the side of books, and PUR type hot melt adhesive is also available, but the cost of using PUR type hot melt adhesive will be slightly higher.
After folding the book pages, smash the pages on the spine to a certain depth to facilitate the penetration of glue, and then apply glue and press down. After this process is completed, wait for the adhesive on the back of the book to dry, and the binding step of the book is completed.
However, if the pages of a book are difficult to stick and can be easily peeled off by milling and applying glue directly on the back, then it is necessary to lock the thread first, apply glue, and then apply glue again to improve the hardness of the spine. In addition, thick books also need to be locked first.
Can books that have already been bound be re bound? ——In theory, it is possible! However, please consider if the reserved glue spine depth is not enough, and the book back that needs to be re glued must also be flattened.
Can different brands of granules be poured into the same glue pot? Direct answer:Not recommended. Different brands of rubber particle substrates and formula systems may not be compatible. Mixing them may result in reduced performance, while mixing them may cause the entire pot to become clogged and scrapped, or the nozzle to be blocked.Many factories […]
Material Overview PE, PP, PVC, PS, PC, POM, EP, ABS, PA, PMMA, etc. are collectively referred to as plastic materials, also known as polymer materials. They are a type of synthetic material with plasticity made from polymer compounds through different processing methods. Plastic materials have the advantages of lightweight, high strength, corrosion resistance, and good […]
Under standardized storage, the shelf life of EVA hot melt adhesive granules is usually 12-24 months; Polyolefin and other systems can last longer. But ‘shelf life’ does not mean ‘just leave it at will’, the environment determines the actual usable time. Key factors affecting shelf life Reference for shelf life of different systems system Reference […]
Direct answer: The smaller the particles, the faster they melt, but to a certain extent, it can lead to new problems such as clumping, clogging, and carbonization. For most book binding and sealing equipment, a standard particle size of 3-5mm is the most comprehensive and optimal, and blindly pursuing small particles is a typical misconception. […]
