What problems may arise if the powder is not completely melted? How to avoid
Reason
Baking temperature control
Solution
Hot melt powder begins to melt at a certain temperature of 130-150 degrees, so it is important to note that if the temperature is too low, it can cause insufficient melting of the hot melt adhesive powder, poor fluidity, and affect the bonding effect.
If the temperature is too high and the hot melt powder melts too much, if the hot pressing time is not adjusted in time, the adhesive layer will penetrate too much, and the surface layer will lack adhesive, which will also fall off.
The operation time of hot melt powder bonding is adjusted according to temperature. When the temperature is high, the time is short. When the temperature is low, it is necessary to extend the time accordingly.
