How To Solve Problems That Occur During The Application Of Adhesive Film
Apr 09, 2024
Among many adhesive films that can be used for material composites, the application frequency of hot melt adhesive films is relatively high. Compared to general liquid adhesive materials, the appearance of adhesive films can better meet the composite needs of similar or different materials, making the final bonding effect better. Nevertheless, there are still many people who encounter various problems during the use of adhesive films, which can affect the final bonding effect. For users, only by promptly removing the factors that affect the bonding effect can the final bonding effect become better.
What problems often occur during the application of adhesive film
Poor adhesion effect of adhesive film
During the application of hot melt adhesive film for material composite, it is necessary to first heat the adhesive film to a certain temperature in order to improve its adhesive properties. If the temperature during composite is not up to standard, it is easy to affect the entire bonding effect. Usually, old-fashioned drum type laminating machines have a relatively large contact area on the entire drum surface and fast heat dissipation speed, which can easily lead to non-compliance with the lamination temperature during subsequent lamination. For such problems, it is often required that the equipment temperature be higher than the normal melting point of the adhesive film.
The adhesive film is not firmly bonded
When using adhesive film to composite materials, if the type of adhesive film used is different from the type of material to be composite, it is easy to cause problems with poor adhesive film adhesion. For such problems, it is generally recommended to solve them by changing the type of hot melt adhesive film.
Poor durability of bonding effect
In most cases, when using adhesive film to composite thinner products, the durability of their bonding effect will be relatively poor. At the same time, it may also be related to the bonding process of the entire material composite. For such situations, it is recommended to avoid secondary heating and melting of the adhesive film as much as possible, in order to avoid the occurrence of re melting of the adhesive film and affecting the overall bonding effect.
