Analysis Of Surface Treatment Of EVA Hot Melt Glue Sheet
- Oct 18, 2017 -

Hot melt adhesive is a plastic adhesive, it is in a certain temperature range of its physical state changes with the temperature changes, and its chemical properties remain unchanged, it is non-toxic and tasteless, are environmentally friendly chemical products. So it is now one of the more commonly used one of the adhesive, but how to choose the right hot melt adhesive? The following aspects are for reference only: hot melt adhesive color: If the adhesive itself is not special color Requirements, then you can use the yellow hot melt adhesive, in general, yellow hot melt adhesive viscosity is better than the white point.EVA Hot Melt Glue Sheet

Surface treatment of the adhesive: hot melt adhesive on the surface of the adhesive is no other adhesive so strict, but the surface of the adhesive dust, oil should also be properly treated, so as to make hot melt adhesive Play a better bonding effect. Adhesive time: bonding fast is a major feature of hot melt adhesive, hot melt adhesive bonding time is generally only about 15 seconds, with the modern production mode that is widely used in pipeline operations, hot melt adhesive bonding time The higher the requirements, that is, the shorter the better, such as book binding and speaker manufacturing hot melt adhesive bonding time required in about 5 seconds.EVA Hot Melt Glue Sheet

Hot melt adhesive on the temperature sensitivity: the temperature reaches a certain degree, hot melt began to soften, below a certain temperature, hot melt will become brittle, so the choice of hot melt adhesive must take full account of the product environment where the temperature changes. Viscous: hot melt adhesive viscosity early adhesive and late viscosity, only the early viscosity and late viscosity consistent, in order to make the hot melt and the adhesive to maintain stability. Of course, in the hot melt adhesive production process, should ensure that it has antioxidant, halogen resistance, acid and plasticity and plasticity, etc., the material is different bonding, hot melt adhesive to play the viscosity is also different, Therefore, different hot melt adhesives should be selected according to different materials.EVA Hot Melt Glue Sheet
