How does the automatic hot melt glue machine work?
Apr 10 , 2023
The hot-melt adhesive system uses a glue pump to heat the turns adhesive into a liquid state and then establish a stable pressure and temperature. It is transported to the spray gun through the throat, and the opening of the nozzle is controlled by a solenoid valve, so that the hot-melt adhesive can be sprayed from the nozzle to the on paper for bonding purposes. How to choose a hot melt adhesive ...

Why there are bubbles after the hot melt adhesive melts
Jul 14 , 2023
Bubbles in the melt will affect the adhesive effect. The first type: The glue contains moisture, and the moisture is vaporized at high temperature and mixed into the glue, and because the glue is relatively viscous, it is difficult for the water vapor to float to the surface and release. The second type: Before using the hot melt adhesive, there are other chemical components mixed in. The former r...
