Quality problems and solutions

Problem one: the PE protection 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 production, and one possibility is that the user is doing it. The mould press used for stamping dies is not enough pressure, 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.


Problem two: the protective film has a good performance in the middle after a period of use, but the main reason for this phenomenon is that the protective film has a greater degree of tension in the process of sticking with the protected sections. After the post is good, the phenomenon of the unnecessary retraction appears in the high temperature environment, and this problem appears in the south. On the product of the customers, 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.


Question three: the most important thing is to protect the film product from the degumming problem. This problem is the most important in 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 remains on the profile product. This is the most reluctant to see, because it is very troublesome. It needs a special person to scrape the glue off the profile. It is particularly difficult and time-consuming. There are many possibilities for this problem. The biggest possibility is that the pressure glue used for protecting the membrane products is not in accordance with the rules, that is, it is too sticky, which causes the PE protective film products to be stripped when they are stripped. The external tension 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.


Problem four: it is difficult to peel off the protective film products. When the product is stripped, the protective film can not be peeled off 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 peeling off. It is also very difficult to be out of time. This is also the most common problem of the protective 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 peel. It is a very headache problem for the users.


Problem five: Although the PE protective film can be effectively stripped but there is a protective film expression on the surface of the profile, this problem is often found on some low-grade protective film products because the protective film is combined with the protected profile, and occurs in a suitable environment such as sunlight water. Combined effect,
