3、PE保护膜在运用一段时间后中心部分完好，但两头翅起，呈现这种现象的

3. The center part of the PE protective film is intact after being used for a period of time, but the two ends are winged up. The primary reason for this phenomenon is that the protective film is stretched to a greater extent during the process of posting the protected profile Afterwards, in a high-temperature environment, it showed a retraction phenomenon. <br> <br>4. The most reflected by PE users is the problem of degumming of the protective film products. This problem is most reflected in the profile protection film. When the user tears the protective film off the profile surface after the profile installation is completed, the protective film shows the viscose It does not follow the protective film, but remains on the profile product, which is the last thing users want to see. <br> <br>5. Although PE protective film products can be effectively peeled off, there are protective film expressions on the surface of the profile. This problem often occurs on some low-level protective film products. This is because the protective film is combined with the protected profile. At that time, there is a kind of chemical interaction that occurs in a suitable environment such as sunlight and moisture.

3, PE protective film after a period of use of the center part intact, but the two wings, the primary reason for this phenomenon is that the protective film in the process of posting with the protected profile, its stretching degree is larger, after the paste, in the high temperature environment, showing the phenomenon of retracting.<br> <br>4, PE users reflect the most is the protection film product de-glue problem, this problem in the profile protection film reflects the most, when the user will be the profile installation and construction after the protective film from the surface of the profile to tear off, the protective film performance of the adhesive is not with the protective film, but left on the profile products, this is the user's last desire to see.<br> <br>5, PE protective film products can effectively peel but in the profile surface residual protective film performance words, this problem in some low-grade protective film products often appear, because the protective film in combination with the protected profile, when there is a suitable environment such as sunlight moisture, and occurred a chemical cooperation.

3. The central part of PE protective film is intact after being used for a period of time, but the two wings rise. The main reason for this phenomenon is that the tensile degree of PE protective film is relatively large when it is pasted with the protected profile. After being pasted, in case of high temperature environment, it presents the phenomenon of retraction.<br>4. PE users mostly reflect the degumming problem of the protective film products, which is most reflected in the profile protective film. When users tear the protective film off the profile surface after the installation and construction of the profile, the adhesive displayed by the protective film does not follow the protective film, but remains on the profile products, which is the last thing users want to see.<br>5. Although PE protective film products can be effectively peeled off, there are still words of protective film on the surface of profile. This problem often occurs on some low-level protective film products. This is because when the protective film is combined with the protected profile, it meets the suitable environment such as sunlight and water content, which is a combination effect.<br>
