PE protective film quality knowledge and transmittance and construction

The PE protective film and the product to be maintained in the middle of the adhesive is not strong, in the transport and use of the whole process of falling situation, the cause of these problems closely follow the problem is the opposite, the greater probability is that the protective film product in the manufacturing of the polyurethane resin viscosity is insufficient, there is a probability that the customer in the case of post mold used in the film press pressure is insufficient, Or the surface of the profile is not cleaned and tidy, there is dust or spray paint, etc., which harms the actual effect of the adhesive. If this problem occurs, it is necessary to treat the cause, remove and replace the sensitive adhesive to increase the working pressure of the glass film, or pay attention to the surface of the profile in the process of the glass film to carry out reasonable and effective cleaning to prevent the occurrence of such problems.

Protective film in the middle of the use of a period of time after the main performance, but the two sides of the wings, the primary factor of this situation is that the protective film in the whole process of adhesion with the maintenance of profiles, its Lasen level is relatively large, after the good post, in the high temperature natural environment, the excess contraction occurred, this problem occurs in the southern region of the user's products, Therefore, PE protective film in the production process need to pay attention to the harm of the natural environment temperature difference on the product application, and avoid a lot of unnecessary surface pull in the whole process of adhesive.

The opening problem of protective film products, this problem reflects more on the protective film of profiles, when the customer removes the protective film from the surface of the profile after the construction of the profile installation project, the main adhesive of the protective film is not accompanied by the protective film, but is residual on the profile product, which is also the customer does not want to see, because it is very inconvenient, It is necessary for full-time personnel to scrape this kind of strong glue from the profile, especially time-consuming and time-consuming, there are various probabilities of these problems, and the greater is likely to be the working pressure glue used for protective film products does not meet the requirements, which is too sticky, resulting in PE protective film products being stripped, the external support force exceeds the thermal stress, and remains on the profile.

PE protective film adopts effective three-layer structure, its surface layer is frosted layer, can effectively prevent the intrusion of fingerprints when used, the general finger slide leaves no trace, even if the residual sweat and other liquid residues, just gently wipe the hand can be cleaned, to maximize the visual effect of the screen, the material is processed by special process, can effectively prevent light reflection, Reduces issues with sunlight and screen reflection.

PE protective film material has higher transmittance, as a liquid crystal screen protective film material without visual impairment, with impact strength, good mechanical properties, impact strength is better than other materials 3 to 5 times, oil resistance, dilute acid, dilute alkali, other solvents.

PE protective film has good weather resistance, the lower can withstand the low temperature of minus 70 degrees, the higher can reach 150 degrees, prevent water vapor penetration, has a good water vapor blocking function, strong protection performance, environmental protection materials, non-toxic and pollution-free, is a real safety material.
