What are the common problems of the protective film bubble treatment method

Protective film bubble treatment method.

(1) Choosing the right ink and improving the coating amount is especially important for the selection of dry composite white ink, and its influence is multifaceted.

(2) Enhance the wettability of the glue to the film, improve the defects of poor local gluing, increase the coating amount, increase the temperature and pressure of the composite roller, use the smooth roller, reduce the composite speed to increase the wetting time and gluing time, choose a good wettability glue and preheat.

(3) Preheat the glue and film and increase the temperature of the composite roller.

(4) Cleaning the coating roller, strengthening the coating amount and the management of the coating roller.

(5) Adjust the viscosity, replace the coating roller, and meet the requirements of the coating amount by matching the glue solid content with the coating roller within the viscosity range that meets the process requirements.

(6) Adjust the drying conditions.

(7) Increase the coating amount and the temperature and pressure of the composite roller, improve the rubber hardness of the roller, increase the rubber hardness of the roller to between 80-85℃, and adjust the "wrapping Angle" Angle of the film before the roller, and enter the composite roller as far as possible according to the tangential direction.

What are the common problems of protective film?

1. The problem of degumming the surface of the protective film, this problem reflects more on the surface protective film of the profile, when the user finishes the installation of the profile after the surface protective film is torn off from the surface of the profile, the adhesive of the surface protective film is not with the surface protective film, but remains on the profile product, if this problem occurs, you can use a clean rag dipped in a little alcohol, Repeated rubbing of the residual sensitive adhesive until the sensitive adhesive is wiped clean, but it should be noted that do not use too much force when rubbing, otherwise it may affect the finish of the profile product, if the surface is plastered with plastic highgloss, the same requirements for the residual adhesive are relatively high, then generally choose a low-viscosity protective film, if the surface is plastered with plates and the like. That also requires a protective film with low viscosity, which is generally sticky.

2. The protective film does not stick well with the product, and the phenomenon of falling off during transportation and use is because the viscosity of the protective film is not enough. If this problem occurs, it is necessary to timely treat the disease and change the protective film with suitable viscosity.
