Quality issues
Question 1: PE protective film and the paste between the protected product is not strong, in the process of transport and the use of the phenomenon of shedding, the reasons for this problem with the previous question on the contrary, the greatest possibility is the protective film products in the production When using the pressure-sensitive adhesive viscosity is not enough, there is a possibility that the user when using the press mold press pressure is not enough, or the surface of the profile is not clean, dust or paint, affecting the sensitive plastic Paste effect! If this problem is to be for the reasons, the right remedy, change the adhesive to increase the pressure on the foil, or pay attention to the surface of the foil during the effective cleaning, to avoid such problems.
Question 2: protective film in the middle of use after a period of good performance, but both ends of the wings, the main reason for this phenomenon is the protective film in the paste with the protection of the process, the greater degree of its stretch, In the future, the case of high temperature, there has been an unnecessary retraction phenomenon, the problem occurs in the products of customers in the South, so PE protective film in the production process should pay attention to the impact of environmental temperature on the use of the product, in the pasting process Avoid unnecessary surface stretching.
Question three: the user reflects the most is the degumming of protective film products, the problem is reflected in the profile protection film up when the user after the completion of the profile installation and construction to tear off the protective film from the surface of the profile, the protective film performance viscose Not with the protective film, but remain in the profile products, which users are most reluctant to see, because it is very troublesome, need someone to scratch the glue from the profile, especially when the labor-intensive, this kind of The problem has many possibilities, the biggest possibility is that the pressure-sensitive adhesive for protective film products does not meet the requirement, which is too sticky, resulting in PE protective film products being stripped, the external tension is greater than the internal stress, and remains in the profile . If you have this problem, you can use a clean rag dipped in a small amount of alcohol, the remnants of the rubber repeatedly rubbed until the rubber was rubbed clean, but need to pay attention to the time in the wipe do not too Hard, otherwise it may affect the profile of product finish.
Problem 4: Peeling of protective film products is difficult. When the profile products are peeled off, the protective film can not be peeled off effectively. There are two reasons for this. One is that the petrolatum used in the pellicle products is not the special pellicle used in the protective film. If it is In this case, the protective film is of course very good at the time of pasting but can be very difficult to peel off, which is also the most common problem with some protective films produced by some illegal protective film manufacturers. Another possibility is that The material used in the protective film master tape is too soft to withstand the pulling force during peeling and causes a breakage during peeling. This is a problem that causes the user a very headache.
Question 5: Although PE protective film products can be effectively stripped, but there is residual protective film performance words on the surface of the profile, the problem in some low-grade protective film products often appear, this is because the protective film and the protected profiles are combined When encountered in a suitable environment such as sunlight, and the occurrence of a combination,
