Why does hot melt adhesive smoke during use?

1. The operating temperature of the machine is too high

People usually think that when using hot melt adhesive, the higher the temperature, the faster the adhesive melts and the faster the gluing speed. In fact, this is a misunderstanding. When hot melt adhesive is melting, its melting speed and temperature roughly present an attenuated oscillating function curve, with peaks and troughs. Therefore, when setting the operating temperature of the machine, it is best to refer to the opinions of the hot melt adhesive manufacturer and set the operating temperature in combination with the actual production situation.

If smoke occurs during the use of hot melt adhesive, you can first lower the set temperature of the machine. If smoke still occurs, contact the relevant supplier to confirm whether the operating temperature is appropriate.

2. Temperature control out of control

The hot melt glue machineis heated by a heating tube, and the temperature sensor reflects the real-time temperature. Therefore, when the temperature sensor fails, the hot melt glue will continue to heat, causing the glue to smoke. Therefore, in this case, the equipment components of the machine need to be replaced in time.

3. The thermal stability of hot melt adhesiveis too poor

Hot melt adhesive with poor thermal stability will deteriorate during use, such as large-scale decomposition of the main body. In this case, the manufacturer should be contacted in time.
