Causes of wire drawing and carbonization of hot melt adhesive particles


1.The temperature of the glue box is too high, some equipment has been used for too long, and the temperature control failure occurs. The actual temperature is lower than the displayed temperature, or the temperature is too high to control it, causing damage to the glue and causing wire drawing.

2. Carbonization of the glue layer on the surface of the hot melt glue box;

3. The thermal stability of the glue itself is not good;

4. The hot melt glue is repeatedly heated in the plastic box for a long time;

5. There are two different types of hot melt glue in the glue box.
