Some Factors Should Be Carefully Considered When Choosing A Bundle Turner

Because the bundle turner has different affinities from different materials to be used, in order to make the bundle turner more "sticky", some factors should be carefully considered when selecting the bundle turner.

1.Color: due to the color of the object is different, the color requirements of the bundle turner should be different. If there is no special requirement for the color of the substrate itself, it is recommended to use a yellow bundle turner. In general, yellow hot melt is better than white.

2.Surface treatment by the binder: The bundle turner of the bundle turner coater is as strict as the surface treatment of the substrate without other adhesives, but the dust and oil on the surface of the substrate should be properly treated to make the bundle turner Better play adhesion.

3.Working time: fast work is a major feature of bundle turner. The operation time of the bundle turner inside the bundle turner coating machine is generally about 15 seconds. With the wide application of the water line in the modern production mode for more than ten years, the operation time of the bundle turner is getting shorter and shorter, such as book binding and speaker manufacturing. The hot melt working time is required to be about 5 seconds.

4.Temperature resistance: bundle turner is sensitive to temperature. When the temperature reaches a certain level, the bundle turner begins to soften. Below a certain temperature, the bundle turner becomes brittle, so the choice of the bundle turner must take into account the temperature change of the environment in which the product is located.

5.Viscosity: The viscosity of the bundle turner is divided into early tack and late stick. Only the early viscosity and the late viscosity are consistent, so that the bundle turner and the substrate can be stabilized. In the production process of bundle turner, it should be guaranteed to have antioxidant, halogen resistance, acid and alkali resistance and plasticity. The viscosity of the bundle turner is different depending on the material of the substrate. Therefore, different bundle turners should be selected according to different materials.
