In the course of transportation and application, the post between PET film for electrical insulation and protected products is not solid and falls off, which is the reason, mainly because the PET film for electrical insulation products in the production of the use of sensitive adhesive viscosity is not enough, there is also a possibility that the user in the mold when the press used in the mold, or the surface of the profile is not clean, has the dust or the paint and so on, has affected the sensitive glue the posting function! Suppose the cause of this problem is targeted, tailored to the case, replace sensitive glue, increase the pressure on the film, or in the film when paying attention to the surface of the profile for a useful cleaning, to avoid such problems.
The main reason for this phenomenon is that when the protective film is applied to the protected profile in the course of its posting, the tensile degree of the film is relatively large, and after the film is finished, it will be exposed to a high-temperature environment, due to the phenomenon of unnecessary retraction, this problem often appears on the products of the customers in the south. Therefore, the production process of PET film for electrical insulationshould pay attention to the effect of environmental temperature differences on the application of the products, and avoid unnecessary surface stretching during the posting process.
There will be a degumming problem in PET film for electrical insulation. This problem is reflected in the protective film of profiles. When users tear the protective film from the surface of profiles after the construction of the profiles is finished, the glue which is embodied in the protective film does not follow the protective film, but remains on the profile products. This is what the users do not want to see because it takes a lot of work and requires a special person to cut up the glue from the profile, special Labor and time-consuming, there are many possibilities of this problem, the most likely is that the pressure glue used in the protective film products is not in line with the regulations, but also too sticky, resulting in the PET film for electrical insulation products in the Peel, the external tension is greater than the internal stress and remains on the profile. If the user has this problem, you can use a clean cloth dipped in a small amount of alcohol, the residue of the glue repeated wipe, until the glue was wiped clean, however, the need to pay attention is in the rub test must not be too hard, otherwise, it may affect the product profile finish.
