Hot melt adhesive (hotglue) is a kind of plastic adhesive. In a certain temperature range, its physical state changes with the change of temperature, but its chemical properties remain unchanged. It is non-toxic and tasteless, and belongs to environmental protection chemical products. Because the product itself is solid, convenient for packaging, transportation, storage, solvent-free, pollution-free, non-toxic; as well as the advantages of simple production process, high added value, high bonding strength, fast and so on, it is favored.
(how to choose a better hot melt adhesive?
1、 The color requirements of glue should be different. If there is no special requirement for the color of the object to be followed, yellow hot melt adhesive is recommended. Generally speaking, yellow hot melt adhesive is better than white adhesive.
2、 Surface treatment of the object to be followed. The hot-melt adhesive is not as strict as other adhesives in the surface treatment of the adherend, but the dust and oil on the surface of the adherend should also be properly treated to make the hot-melt adhesive play a better role in bonding.
3、 Operation time. Fast operation is a major feature of hot melt adhesive. The operation time of hot-melt adhesive is generally about 15 seconds. With the wide application of modern production mode assembly line, the operation time of hot-melt adhesive is required to be shorter and shorter. For example, the operation time of book binding and speaker manufacturing is required to be about 5 seconds.
4、 Temperature resistance. Hot melt adhesive is sensitive to temperature. When the temperature reaches a certain degree, the hot-melt adhesive begins to soften. If it is lower than a certain temperature, the hot-melt adhesive will become brittle. Therefore, the temperature change of the product environment must be fully considered when selecting the hot-melt adhesive.
5、 Stickiness. The viscosity of hot melt adhesive can be divided into early viscosity and late viscosity. Only when the early viscosity is consistent with the later viscosity can the hot melt adhesive keep stable with the adherent. In the production process of hot melt adhesive, it should be guaranteed that it has the properties of anti oxygen, anti halogen, anti acid and alkali, and plasticizing. The viscosity of hot-melt adhesive varies with the material of the object to be followed. Therefore, different hot-melt adhesive should be selected according to different materials.
