Often customers encounter this confusion: the hot melt adhesive film taken somewhere, when the sample finds that the bonding effect is too poor and the adhesion is not firm, so there will be the idea that the hot melt adhesive film is not suitable for his product to use. Whether the hot melt adhesive film is really not suitable for his product use, we are not good at conclusive, but we need to first analyze why the hot melt adhesive film is not firmly adhered to?
Compared with the traditional water-based adhesives we are familiar with, hot melt adhesive films have very obvious advantages in terms of environmental performance and bonding effect. Even so, it may be that for a long time, many industries will still use water-based adhesives as adhesives. However, with the continuous deepening of the concept of environmental protection, it is imperative to switch to a more environmentally friendly hot melt adhesive! For customers who use hot melt adhesive film for the first time, the price and the degree of bonding are the two issues that are more concerned.
First, the selection error
Selection error mainly refers to the choice of hot melt adhesive film or hot melt adhesive mesh film model is not right, it is difficult to meet the requirements of the material itself bonding, can be solved by replacing the corresponding model.
Second, the temperature during recombination does not meet the requirements
The composite temperature does not reach the melting point of the film or the oment, resulting in insufficient melting of the hot melt adhesive and not giving full play to the bonding performance. In this case, it may be that the composite surface of the machine cannot reach the melting point of the film, or the thermal permeability of the material is poor. If the machine temperature reaches the upper limit and still cannot be solved, a low-temperature hot melt adhesive film test can be used. In addition, under the premise of ensuring that the material is not burned, the surface layer with good thermal permeability is selected for pressurized heating.
