How to avoid degumming when using the protective film of aluminum plastic plate?

Click:Date:2020/10/10
Degumming has become a common phenomenon of protective film and tape. Of course, this phenomenon is not good. Generally speaking, the quality of the product itself should be too hard, so it is a big problem to pay attention to in the production. Now, let's feel what we can do to help us avoid this.

The analysis shows that the general reason is that the protective film of the aluminum plastic plate must be torn off from the surface of the profile after the construction of the user's equipment. However, the adhesive of the protective film does not follow the protective film, but remains on the contour of the product. This is the most reluctant achievement we will see.

It may be that the pressure glue used in the protective film products generally does not meet the requirements, but in other words, compared with the viscosity, this will lead to the peeling of the protective film products when the external force is greater than the internal force.

Therefore, the residue on the contour usually makes the protective film of aluminum-plastic plate unable to peel off effectively. Generally speaking, there are two possibilities. One is the photosensitive adhesive used in the protective film products of aluminum-plastic plate, and the other is the photosensitive adhesive not used for the protective film. However, the protective film plays a good role in pasting, but it plays a good role in stripping. In general, it's hard to compare them. This is also the most common problem compared to those produced by some illegal manufacturers of protective films.

Another possibility is that the material used in the protective film tape of aluminum-plastic plate is too soft, of course, it can not bear the tensile force during stripping, so the cracking phenomenon will occur during stripping. Generally speaking, this is a very * problem for users.

Therefore, the key is to pay attention to the production of aluminum-plastic plate protective film. In the production, we should strengthen the control and adjustment of relevant factors, solve problems, and help us better complete the things we must do.
