Precautions for the purchase and use of carton hot melt adhesive
Carton hot melt adhesive is a kind of plastic adhesive. Its physical state changes with the change of temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product. Because the product itself is solid, it is easy to package, transport, store, solvent-free, pollution-free, and non-toxic; as well as the advantages of simple production process, high added value, high bonding strength and fast speed.
How to choose the carton hot melt adhesive?
1, the color requirements of the glue should be different. If the attached object itself has no special requirements for color, it is recommended to use yellow hot melt adhesive. Generally speaking, yellow hot melt adhesive is more viscous than white.
2. Surface treatment of the object to be attached. The surface treatment of the hot melt adhesive is not as strict as other adhesives, but the dust and oil on the surface of the adhered should also be properly treated, so that the hot melt adhesive can play a better role in bonding.
3. Working time. Fast operation is a major feature of hot melt adhesives. The working time of hot melt adhesive is generally about 15 seconds. With the wide application of modern production methods – assembly line, the working time of hot melt adhesive is getting shorter and shorter, such as book binding and speaker manufacturing. It takes about 5 seconds.
Fourth, temperature resistance. Hot melt adhesives are more sensitive to temperature. When the temperature reaches a certain level, the hot melt adhesive begins to soften. Below a certain temperature, the hot melt adhesive will become brittle. Therefore, the choice of hot melt adhesive must fully consider the temperature change of the environment where the product is located.
