- Dec 25, 2018 -

Since the advent of aluminum panels in the late 1980s and early 1990s, they have rapidly been affected by their economy, diversity of alternative colors, convenient construction methods, excellent processing performance, excellent fire resistance and noble quality. People's favor. Aluminum plates have played a greater role in building exterior walls, curtain wall panels, renovation and refurbishment of old buildings, indoor wall and ceiling decoration, advertising signs, display stands, and dust purification projects. However, many people have found that over time, The protective film on the aluminum plate is difficult to tear, so how to tear aluminum protective film?

The side of the protective film covered on the surface of the aluminum-plastic panel that is in contact with the aluminum-plastic panel is coated with a layer of glue and has a certain viscosity. Under normal conditions, the protective film is easier to tear off. If the protective film on the surface of the aluminum plate does not tear well, there is a possibility that the aluminum-plastic composite plate is stored for a long time and there is no care. When the aluminum-plastic composite plate is stored at a high temperature, the coating layer of the protective film will be in a semi-"melted" state. The adhesion to the surface of the aluminum-plastic panel is increased, resulting in difficulty in tearing. So for these situations, how to tear aluminum protective film?

If the aluminum plate is not used for a long time, Delta recommends that you do not use alcohol and other cleaners, but rather be patient and slowly tear it by hand. The speed of tearing is slow, and the tearing direction is as much as about 90° to the board surface, so that the tackiness of the protective film does not decrease. Of course, you can also use a sharp knife to draw some parallel marks on the protective film. The width of the parallel line is about 10cm, but you must master the strength.
