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 ...

Hot melt glue machine filter cleaning
Jun 28 , 2023
Cleaning steps of hot melt adhesive machine: 1. It is necessary to set the temperature of the hot melt adhesive machine system to the operating temperature; 2. Remove the filter from the branch seat, and check whether the filter needs to be replaced; 3. If it needs to be replaced, install a new filter, and at the same time use a new sealing ring and apply high-temperature oil; 4. If it does not ne...

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...

The importance and key points of PUR edge banding
Aug 11 , 2023
The importance and key points of edge banding Edge banding is a point that cannot be ignored in the manufacture of wooden doors. In fact, a good and strict edge banding board not only makes the wooden door good or bad, but also determines the service life of the wooden door, as well as its aesthetics and environmental health. There is another important point, that is, the unavoidable application o...

Why does hot melt adhesive smoke during use?
Sep 08 , 2023
1. The operating temperature set by the hot melt adhesive machine is too high Usually people think that when using hot melt adhesive, the higher the temperature, the faster the melt adhesive and the faster the gluing speed. Actually, this is a misunderstanding. When the hot-melt adhesive is melting, the velocity and temperature of the hot-melt glue are roughly an attenuating oscillatory function c...

Why is it not recommended to mix hot melt glue?
Nov 03 , 2023
Each adhesive has specific properties. Even if hot melt adhesives look the same, that doesn't mean they have the same chemical structure. 2 reasons why mixing is not recommended 1. Clogging of hoses and hot melt glue guns Suppose you change from a hot melt adhesive that is used at 150-170°C to one that is used at 130-150°C. What happens if you mix new hot melt glue into the old glue in the glue ta...

Why does PUR hot melt adhesive appear stringing and bubbles?
Nov 08 , 2023
Cohesive strength of PUR hot melt adhesive machine The law of influence between the cohesive strength of PUR hot melt adhesive colloid and wire drawing is: if the cohesive strength is large, the wire drawing phenomenon will be obvious; on the contrary, if the cohesive strength is small, the wire drawing phenomenon will not occur. PUR hot melt adhesive curing time The curing time of PUR hot melt ad...
