In the face of many kinds of hot melt adhesive, WALTE recommends that you correct ion of hot melt adhesive
A, the color of the plastic requirements should be different. If it is then itself has no special requirement to recommend the use of color, yellow hot melt, in general, better than the white viscous yellow glue.
Two, was followed by surface treatment. Hot melt adhesive on the surface treatment material is then no other adhesive so strict, but then dust, surface oil should also make the appropriate treatment, can better play the role of hot melt adhesive.
Three, operating time. Fast operation is a major characteristic of hot melt adhesive. The operation time of hot melt in 15 seconds, with the wide application of the modern mode of production - line, the operation time of hot melt adhesive requires more and more short, such as bookbinding and speaker manufacturing operation time on the hot melt adhesive required to reach about 5 seconds.
Four, anti temperature. Hot melt adhesive is more sensitive to temperature. The temperature reaches a certain degree, hot melt begin to soften, below a certain temperature, hot melt will become brittle, so choose the temperature change of hot melt adhesive must fully consider the environmental products.
Five, viscosity. Hot melt adhesive is divided into early and late sticky sticky. Only early and late sticky sticky consistency, in order to make the hot melt and then things remain stable. In the production of hot melt process, should ensure that it has antioxidant, anti acid alkali and halogen, plasticizer. By then the different materials, played by hot melt adhesive is also different, therefore, should according to different materials, different choices of hot melt adhesive.
