How to obtain good performance of hot melt adhesive for books? Your primary task throughout the day is to ensure that everything in the factory runs smoothly and efficiently to achieve high output. Although it is only a small part of the entire process, it includes your hot melt operation.
There are many factors that can affect the performance of hot melt adhesive, but understanding the good practices that each hot melt adhesive user should follow will increase your chances of achieving good results for your application.
Please follow the following 3 A tip to ensure that the hot melt adhesive for books performs well:
1. Apply glue at an appropriate temperature: Temperature is an extremely important variable for the success or failure of hot melt adhesive application in books. If the adhesive is too hot, it will take longer to bond and may lead to a good description of “gum failure” (learn more here). If the temperature of the adhesive is too low, it may solidify prematurely and cause weak bonding. This is called a preset. Follow the manufacturer’s TDS to obtain the recommended application temperature range and make corresponding adjustments.
2. Keep the glue can full: Remember to keep the glue can full during use. When the adhesive level is too low; Hot spots and gel formation may occur, leading to carbonization. If you manually load them, it’s easy to forget to refill the flowerpot. Having an automatic filling system to replenish adhesive as needed and a liquid level control system to monitor adhesive levels will ensure that your tank remains full. This can supplement the antioxidants in the adhesive to combat carbonization.
3. Reduce the pot temperature when not in operation: Due to the continuous thermal stress on the hot melt tank, hose, and nozzle, they have a tendency to produce coke. Reduce the pot temperature when not in use to minimize any potential thermal degradation of the hot melt adhesive and equipment. This will reduce the chance of carbonization occurring.
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 […]
Is environmentally friendly hot melt adhesive really environmentally friendly? Hot melt adhesive has fast bonding speed, stable performance, and is conducive to sustainability. Automation technology tells operators that it is highly cost-effective. And in the process of using hot melt adhesive, there is no need for a drying process, the bonding process is simple, the […]
Why does pearl cotton hot melt adhesive have wire drawing? During the process of gluing pearl cotton with a drum hot melt glue machine, some customers may find that the hot melt glue has a wire drawing phenomenon. The wire drawing of the hot melt glue not only affects the construction efficiency, but also affects […]
hot melt adhesiveWhen the glue pot has burnt particles, uneven glue dispensing, or impurities in the glue line, simply replacing the glue may not solve the problem. This article sorts out the troubleshooting sequence according to “glue pot status, temperature setting, shutdown habits, and glue supply path” to help reduce downtime and material waste in […]
