1. Set the appropriate temperature according to the glue parameter table. Whether it is a hot melt adhesive carton sealing machine or a hot melt adhesive carton opening machine, there are specific requirements for the temperature settings of the three areas: the glue tank, the glue hose, and the glue gun. Users must set the corresponding parameters according to the performance of the glue machine. Do not set an extremely high temperature just for better melting of the glue.
2. Determine the amount of glue to be added based on the usage. Although the glue tank of the glue machine has a large space, it is not recommended that users fill the glue tank every time and then repeatedly heat and cool it for use every day. This will cause the hot melt adhesive to be repeatedly heated and burned, and eventually it will carbonize. You can decide how many glue particles to add according to the daily usage, and don't add too much.
3. Storage of the glue. Before melting, the hot melt adhesive is in granular form. Many manufacturers ship it in plastic woven bags. Sometimes, after users open the bags during use, they no longer seal them, which is incorrect. If not sealed, impurities or contaminants will enter the bags, thus contaminating the hot melt adhesive particles. These particles will have impurities after melting, which will not only clog the spray nozzle but also affect the glue spraying effect.
Avoiding the carbonization of hot melt adhesive is the most effective way to prevent failures of hot melt adhesive machines. The above are the first three points summarized by YUPACK on how to avoid the carbonization of hot melt adhesive. In the future, YUPACK will continue to update other reasons for avoiding the carbonization of hot melt adhesive for you. Thank you for your continuous attention!
