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. EVA eco-friendly hot melt adhesive is a thermoplastic material composed of EVA, tackifiers such as petroleum and rosin, as well as some bonding AIDS, and is formed in solid cylindrical rods or granular form. It can be melted and applied by using a hot melt gun, sprayer or other glue binding equipment, etc. Because it […]
What is wireless adhesive bonding? Wireless adhesive binding refers to a binding method that uses adhesive to fix the pages of printed materials on the spine of a book. Unlike traditional wired binding, wireless adhesive binding does not use wire or thread, but instead uses glue to bond the book core. The book core processed […]
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 […]
What are the uses of filter gel? An air filter is a component used to purify the air. Filters are generally used in farms, laboratories, sterile rooms, car engines, car air conditioners, household air conditioners, household air purifiers, etc. 1、 Hot melt adhesive for flat filter The commonly used filter cartridge adhesive is the high-efficiency […]
