Problems and solutions of Weiwang hot melt adhesive used under high temperature in summer

Now it is April, and the high temperature in summer is coming quietly. When the hot melt adhesive is in high temperature in summer, it will be prone to some problems. Now let's learn about the problems and solutions of Weiwang hot melt adhesive when it is used in high temperature in summer.

Hot melt adhesive is prone to wire drawing in summer

1. The temperature is too high

2. The adhesive adhesion is too low or too high

3. Too much glue

Solution: the temperature is too high in summer. When these problems occur, the manufacturer needs to reduce the temperature, increase the viscosity value, reduce the amount of glue, and prevent excess glue from appearing outside. Some adhesives are of poor quality. You can choose adhesives with high adhesion. Weiwang hot melt adhesive is a good choice.

Reasons for long opening time of hot melt adhesive

The ambient temperature is too high and the cooling time of the glue is prolonged, so it dries slowly

Solution: properly cool down the production environment, reduce the amount of glue and reduce the operating temperature.

Reasons for uneven edge sealing

PVC is not resistant to high temperature

The temperature of the glue is too high and the cooling is slow

Solution: reduce the temperature and replace the high temperature resistant adhesive strip.

The above points are explained according to the problems in the use of hot-melt adhesive in summer. The performance of rubber sticks is different, and they are also different in seasonal use, so we should buy different rubber sticks according to different performance. Weiwang hot melt adhesive manufacturer produces good hot melt adhesive rods according to their different properties in different seasons.
