Why does it fluctuate when I use hot melt adhesive mesh for lamination?
Hot melt adhesive mesh is a commonly used type of adhesive on the market, which is mostly used for laminating between products of the same or different types. In practical applications, there are many factors that can affect the strength of its adhesion, such as its color, the cleanliness of the composite surface, and the adhesive period of the material itself. Therefore, when using hot melt adhesive mesh for composite, it is important to pay more attention to keeping away from factors that may affect the adhesion of the mesh, in order to improve the final bonding effect. The factors that affect the adhesion of the omentum mainly include the following: 1. Retinal membrane color:Compared to white or other colored membranes, yellowed membranes have stronger adhesive properties. If there are color requirements for the non adhesive parts of the required composite, it would be better to choose this type of mesh for bonding. 2. Surface cleanliness of the adhesive:Before bonding the item with a mesh film, clean the entire surface of the adhesive of any stains, oil stains, etc. This way, the composite effect will be better. 3. The adhesiveness of the omental cutting itself: The adhesiveness of the omental cutting mainly includes two types: early and late stages. The same adhesiveness before and after stages is necessary to improve the final bonding effect. 4. Temperature effect: Hot melt adhesive mesh has a high sensitivity to temperature changes. If the temperature exceeds the temperature requirements of the mesh itself, the entire mesh will become too soft. If the temperature is lower than the required standard, the entire omentum will become brittle and also affect the adhesion of the entire omentum. Therefore, when using omentum for composite treatment between objects, it is necessary to consider the changes in the surrounding environment temperature. In addition to the above factors that can cause changes in the adhesion of the entire mesh, the length of the bonding cold sink time when using hot melt adhesive mesh for composite can also directly affect the overall bonding effect. When bonding the fabric surface and plush fabric, it is necessary to require a time of at least 5 seconds, which is also one of the issues that everyone needs to pay more attention to when using.
