1.the PE protective film and the protected product are not firmly attached to the product in the process of transportation and use. The reason for this problem is quite the opposite. The biggest possibility is to protect the viscosity of the pressure sensitive adhesive used in the production, and the possibility is that the user is in the mold. The pressure used by the die press is not enough, or the surface of the section is not clean, and there is dust or paint, which affects the paste effect of the adhesive. If this problem appears, it is necessary to counter the reason, change the sensitive adhesive to increase the pressure of the sticker, or pay attention to the effective cleaning of the surface of the profile when the film is sticker, so as to avoid the appearance of such problems.
2. the protective film has a good performance in the middle after a period of use, but the two ends of the wing, the main reason for this phenomenon is that the protective film is in the process of sticking with the protected section, its tensile degree is larger. After the post is good, the phenomenon of unnecessary retraction appears in the high temperature environment. This problem appears mostly in the South customers. In the product, the PE protective film should pay attention to the effect of the environmental temperature difference on the use of the product in the production process, and avoid unnecessary surface stretching during the bonding process.
3. The most reflection of the user is the degumming of the protective film products. This problem is most reflected on the profile protection film. When the user tore the protective film from the surface of the profile after the installation of the section, the adhesive of the protective film is not along with the protective film, but it is used in the profile product. Because it is very troublesome, because it is very troublesome, it needs a special person to scrape the glue from the profile, especially for the time and time. There are many possibilities for this problem.
The biggest possibility is to protect the pressure glue for the film products, that is, it is too sticky, and the PE protective film product is removed when it is stripped. The force is greater than the internal stress and remains on the profile. If the user appears this problem, can use a clean cloth dipped in a little alcohol, the residue of the sensitive adhesive repeated trial, until the sensitive adhesive is clean, but it is necessary to pay attention to the erasing must not be too hard, or may affect the profile product's finish.
4. It is difficult to peel off the protective film products. When the product is stripped, the protective film can not be stripped effectively. There are two possibilities. One is that the sensitive adhesive used for protective film products is not a special sensitive adhesive for protective film. If so, the protective film is very good when it is stickup, but it is stripped. It will be very difficult. This is also the most common problem of the protection film produced by the producers of illegal protective film products. There is also a possibility that the protection of the material used by the membrane is too soft to withstand the pulling force of the peeling. It is a problem that makes the users very headache.
