The shape of the hot melt adhesive is solid, granule, powder, etc. It must be heated to above the softening point at high temperature to convert the solid or powder into a liquid. After bonding the product, it is then supercooled or placed at room temperature. back to solid. The advantage of hot melt adhesive is that it can be reused, has high adhesion, no peculiar smell, is environmentally friendly, and has a great filling effect.

The strength of other adhesives on the surface of the bonding object is better than that of the hot melt adhesive, so the oil and dust on the surface of the bonding object should be cleaned, so that the hot melt adhesive can play a good role in bonding and achieve satisfactory results. One of the features is high work efficiency.

When the temperature reaches a certain level, the rubber body will slowly begin to soften. When it is higher than the softening point, it will become a liquid body. When the temperature is lower than a certain temperature, the rubber body will become brittle, and the lower the temperature, the The more brittle it is, so when choosing to use hot melt adhesive, it is necessary to fully consider the changes in the ambient temperature of the products that are bonded by hot melt adhesive. Different ambient temperatures use hot melt adhesives with different formulations.

The use of hot melt adhesive is actually very simple. Unprofessional people usually use a lighter to heat it for use at home. However, the operability and safety are not high, and it is easy to burn hands and cause injury. Therefore, the best way is to buy hot melts in a hardware store. The glue gun is used to use hot melt glue, which is safe and convenient.

The temperature of hot melt adhesive is very high during work, and it is easy to burn the body, so special attention should be paid during operation, protection must be done, and safety awareness should be improved, such as wearing gloves and masks. At present, only good quality hot melt adhesive can be used in the field of industrial manufacturing, and the temperature resistance and flame retardant performance can be guaranteed. At present, the products of big brands that can meet this quality requirement are widely used, and can be used in new energy, military industry , medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.
