In the chemical industry, adhesive tape, فيلم واقية, and the adhesive market is rapidly expanding, adhesive tape, protective film, and adhesive are widely used in electronics, mobile phones, optoelectronics, communications, packaging, construction, papermaking, aerospace, automotive, textile, metallurgy, mechanical manufacturing, medical industry and so on. At present, China’s adhesive products with an annual growth rate of more than 13%, have become one of the dynamic industry forces in China’s chemical industry.
1, protective film, and protected products paste is not strong, in the process of transport and use appear to fall off phenomenon, the reasons for this problem to keep up with a question on the contrary, possibility is the sensitive adhesive used in protective film products in the production of insufficient, there is another possibility is that the user to post-mold molding machine used by the pressure is not enough, or the profile surface is clean, no dust or paint, etc., influenced the sensitive adhesive paste effect! If there is this problem will be targeted at the cause, the appropriate medicine, change the sensitive adhesive, increase the pressure of the film, or pay attention to the surface of the profile of effective cleaning when the film, to avoid the occurrence of such problems.
2, although can effectively stripping protective film products in material surface residual have a protective film, the problem often occurs in some low levels of protective film on the product, this is because the protective film between the and protected material combination, in the right environment, such as sunshine moisture, a combination of the combination there is no good method can be avoided, because it has no regular reproduction, so, for now, this problem is not a good way to avoid living!
3, stripping difficulty protective film products, while the profile products installed for stripping, the protective film can’t effectively stripping, investigate its reason has two possibilities, one is protective film sensitive adhesive used for the product is not a special sensitive adhesive protective film, if so, the protective film on the paste when the effect is very good, of course, but will be very difficult in the shed, which is why some illegal protective film products manufacturers produced a protective film of the most common problems, there is also a possibility is used in protective film master material too soft, can’t bear the tension when the stripping when stripping appear rupture phenomenon, this is to let users very headache problem.
Among 4, protective film after using for a period of time performance is good, but on both ends of the wing, appear this kind of phenomenon is the main reason of the protective film with protected by profile during the process of paste, the drawing is bigger, after the good post, in a high-temperature environment, appear the phenomenon of unnecessary retraction and this problem appears more customers in the south, so the protective film in the production process should pay attention to the effects of environmental temperature on product use, avoid unnecessary surface tension in the process of paste.
It can be said that the huge demand for industrialization is the driving force of the development of protective film companies, and the development of protective film industry will continue to move forward steadily.
