How To Solve The Problem Of Degumming And Residual Glue Of PE Protective Film?
Dec 29, 2021
The degumming and residual glue of the protective film have always been a headache, so how can we solve it? Today I will share with you some tips.
Many electronic processing plants sometimes use PE protective film that does not meet the requirements in the process of using PE protective film to protect the profile. The phenomenon of degumming of the PE protective film sometimes occurs, which affects the surface finish of the profile. At this time, how should we solve this phenomenon?
The residual glue of the protective film actually has a great relationship with the peeling force of the protective film. Generally speaking, the viscosity is proportional to the peeling strength of the protective film. The stronger the viscosity, the worse its peeling strength; in addition, the quality of the adhesive The worse, the worse the peel strength. We usually add some adhesion additives when applying the film, or replace the glue to reduce the appearance of residual glue. The problem of residual glue is mostly because the product did not choose the right viscosity when choosing the protective film. The viscosity of the selected protective film is too sticky, which will easily cause residual glue when the product is peeled off.
When the PE protective film is degummed, a clean rag should be dipped in a little alcohol, and the remaining sensitive glue should be wiped repeatedly until the glue is wiped clean. And in the process of wiping, pay attention to the strength of wiping, not too hard, otherwise it may affect the finish of the profile product.
Adhesive reminder, the degumming phenomenon of PE protective film used on the profile is basically caused by the use of unqualified or too strong PE protective film. The occurrence of this phenomenon will seriously affect the surface finish and use of the profile, and later The processing is also very troublesome. It requires a special person to carefully wipe the remaining degumming with a rag dipped in a small amount of alcohol, which is a waste of time and also affects the progress and cost of the processing.
Therefore, when using PE protective film, you should choose a PE protective film of excellent quality. For example, choosing a good quality PE protective film will prevent the occurrence of degumming of the PE protective film when it is used on the profile.
All in all, we should pay attention to these problems when purchasing protective films. Each product has its own film requirements with different viscosities. If you pay attention to these when ordering, you can avoid the problems of degumming or residual glue.
