Hot melt adhesive affinity because different materials were different then, in order to better play the hot melt adhesive "sticky", it should be careful in the choice of hot melt adhesive to consider the following factors:
First, the color. Then because of different colors are objects of the hot melt adhesive color requirements should differ. Then no matter if they are their own special requirements for color, we recommend the use of yellow hot melt adhesive, in general, better than the white sticky yellow hot melt adhesive.
Two, to be followed by surface treatment. Hot melt surface treatment to be followed by any other adhesive material so strict, but was followed by surface dust, oil should also make the appropriate treatment, in order to make better use hot melt adhesive action.
Third, the operating time. Job fast is a major feature of hot melt adhesive. Hot Melt working time is generally about 15 seconds, with modern production methods - widely pipeline, hot melt adhesive to the job requirements of increasingly short time, such as bookbinding and speaker manufacturing operation time of the hot melt adhesive required to achieve approximately 5 seconds.
Fourth, resistance to temperature. Temperature-sensitive hot melt adhesive. The temperature reaches a certain level, the hot melt adhesive begins to soften, below a certain temperature, the hot melt adhesive becomes brittle, so I chose the hot melt adhesive must be fully taken into account the environment in which the product temperature changes.
Fifth, sticky. Hot melt viscosity and tack points early post-sticky. Only early and late sticky viscous consistency, and to be followed in order to make hot melt adhesive material remains stable. Hot melt adhesive in the production process, we should ensure that it has antioxidant, anti-halogen, acid alkaline and plasticity.
Was then goo different materials, hot melt plays are different, therefore, should be selected depending on the different hot melt materials
