The difficult problem of degumming of PVC protective film:
Regarding the degumming problem of PVC protective film products reported by users, this problem is most reflected in the profile protective film. When the user has completed the installation and construction of the profile, he should pay attention to tearing off the PVC protective film from the surface of the profile. The viscose does not follow the protective film, but remains on the profile product, which must be the last thing users want to see, and it is also very troublesome.
In view of the problems reflected by PVC protective film products, it is necessary to have a special person to scrape these glues off the profiles. At this time, it will be particularly labor-intensive and time-consuming. There are many possibilities for this problem. The biggest possibility is The pressure glue used for protective film products does not meet the regulations, that is, it is too sticky, which causes the external tension of PVC protective film products to be greater than the internal stress when peeled off, and remains on the profile.
When users use PVC protective film products, if they find this problem, they must pay attention to use a clean rag to dip a little alcohol, and repeatedly wipe the residual sensitive adhesive until the sensitive adhesive is wiped clean, but It should be noted that when wiping, do not use too much force, otherwise the finish of the profile product may be affected.
Difficulty in peeling off PVC protective film:
PVC protective film products are difficult to peel off. When the profile products are installed and peeled off, or when the protective film cannot be effectively peeled off, there are two reasons for this. One is that the sensitive adhesive used in protective film products is not dedicated to protective film. For sensitive adhesives, there is also a possibility that the material used for the protective film master tape is too soft to withstand the pulling force during peeling, and it breaks during peeling, which is a very headache for users.
Finally, it is also necessary to pay attention to the use of PVC protective film products. Although it can be effectively peeled off, there are still PVC protective film products on the surface of the profile. This problem is in some low-level protective films. It often appears on products, which is a chemical effect that occurs when the protective film is combined with the protected profile when it encounters a suitable environment such as sunlight and moisture.
