Do hot melt adhesive particles need to be reheated before opening when taken out of the cold storage? Comparison between room temperature and cold storage storage

Conclusion

I need it. Taken from a cold storage or low-temperature environmentHot melt adhesive granules，It must be warmed up to room temperature in the workshop before openingOtherwise, if the outside of the bag is cold and the air is hot, water vapor will condense on the surface of the particles, causing bubbles, white spots, and weak adhesion when the machine is used. Compare the two methods of “cold inventory” and “room temperature memory” below.

Cold storage: saves space but is prone to condensation

In summer, the workshop is hot, so it is right to store the rubber particles in the cold storage to prevent softening. However, if the bags are directly torn off during the outbound process, moisture will instantly condense on the particles. The correct approach is to move the bag to the workshop and let it sit for 4-8 hours to warm up before opening it. When the bag surface is no longer cold, open it again.

Indoor storage at room temperature: convenient but afraid of high temperatures

Rubber particles are most afraid of long-term high temperature and sun exposure. As long as the room temperature is cool, ventilated, not exceeding 30 ℃, and far away from heat sources, it is actually more convenient than cold storage and prevents condensation. The disadvantage is that the temperature in the south may be higher in summer, and temperature control storage is required.

FAQ

Q: What happens if the temperature is not enough to return to the machine?
Answer: The particles carry water, and when they melt, the water vapor turns into bubbles and white paper, causing a decrease in adhesion and making the back of the book flower.

Q: Can the adhesive that has already condensed still be used?
Answer: Slightly spread it out and let it dry in the shade before drying it again; It is recommended to discard items that have been severely affected by moisture and clumping. Don’t gamble.

Question: How to store it most stably?
Answer: Guangzhou Sunlife TradingSunlife Hot Melt AdhesiveEach bag has a moisture-proof lining and is equipped with a cool storage and outbound temperature recovery process, which can also be managed in small batches.

Remember: The rubber particles taken out of the cold storage should be warmed up before opening, and the temperature should be controlled in the room at room temperature to prevent condensation and white spots from coming knocking on the door.
