hot melt adhesive powder is a plastic adhesive product. The physical state of hot melt adhesive powder changes with the change of temperature within a certain temperature range, while the chemical properties remain unchanged. hot melt adhesive powder is non-toxic and odorless. It is an environmentally friendly glue product variety. hot melt adhesive powder can be used for packaging in various industries. hot melt adhesive powder is used to melt hot melt adhesive powder through heat, and the adhesive after melting becomes a liquid. Through the hot melt glue machine hot melt hose and hot melt glue gun, sent to the surface of the bonded material, hot melt glue after cooling to complete the bonding.
The color requirements of glue should be different. If the object itself has no special requirements for color, it is recommended to use yellow hot melt adhesive. Generally speaking, yellow hot melt adhesive is better than white adhesive. It is treated on the outside. The hot melt adhesive is not as strict as other adhesives on the surface of the object, but the dust and oil on the surface of the object should also be properly treated, so that the hot melt adhesive powder can better display the bonding effect.
Fast operation is a major feature of hot melt adhesive. The working time of hot melt adhesive is generally about 15 seconds, and with the wide application of modern production mode – assembly line, the working time requirements for hot melt adhesive are getting shorter and shorter, such as book binding and speaker manufacturing, the working time requirements for hot melt adhesive are about 5 seconds. Hot melt adhesive is 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 selection of hot melt adhesive powder should fully consider the temperature change of the environment where the product is located.
