Rainbow streaks appear on the protective film

In our daily life, rainbow stripes are very common in the protective film, because the pet protective film is caused by the hardening treatment, because the hardening treatment needs to go through a high temperature, a high temperature will make the molecules on the surface of the pet protective film show a dispersed state, and once the molecules appear dispersed, rainbow stripes will appear. And the higher the hardness, the more likely it is to appear rainbow lines, rainbow lines will be more serious, this is why often only the hard pet above can see the rainbow lines, like the ordinary process of pet protective film is rarely rainbow lines, unless there is a problem with the substrate itself, the substrate thickness is not uniform, Rainbow lines are also possible in this case.

So, what does the rainbow pattern of the protective film do to our daily life?

The appearance of rainbow stripes will cause certain damage to our eyes, because the appearance of rainbow stripes will lead to the reduction of the transmittance of the protective film, so that the original color we see is inconsistent with the actual color, resulting in distortion. Therefore, when the protective film with rainbow stripes fits the mobile phone, tablet, and other devices we use, it will interfere with our vision and affect our visual experience.

Do you know how to solve the rainbow streaks in the protective film?

Want to solve the problem of protective film rainbow lines, one is to control the hardness of the protective film when doing hardening treatment, when the hardness of the protective film is below 4H, rainbow lines will be relatively better controlled, but more than the hardness of the rainbow lines will be relatively obvious; Then is in the selection of substrate, try to choose some quality control is more strict, better quality substrate, can also avoid the phenomenon of rainbow lines.
