Industrialization demand is the source of protective film development

In the chemical industry, the adhesive tape, protective film and self-adhesive market are expanding rapidly. Adhesive tapes, protective films and stickers are widely used in electronics, mobile phones, optoelectronics, communications, packaging, construction, papermaking, aerospace, Automotive, textile, metallurgy, machinery manufacturing, medical industry, etc. At present, China's adhesive products are growing at a rate of more than 13% per year, and have become one of the dynamic industry forces in China's chemical industry.

      The adhesion between the protective film and the protected product is not strong, and it appears to fall off during transportation and use. The reason for this problem is exactly the opposite of the previous problem. The possibility is that the protective film product is used in the production of sensitive adhesive. There is not enough, there is a possibility that the pressure of the molding machine used by the user when the mold is being used is not enough, or the surface of the profile is not clean, dust or paint, etc., which affects the adhesive effect of the sensitive glue! If this problem occurs, it is necessary to aim at the cause, the right medicine, replace the sensitive glue, increase the film pressure, or pay attention to the effective cleaning of the surface of the profile when the film is applied to avoid such problems.

      Although the protective film product can be effectively peeled off, there is a protective film on the surface of the profile. This problem often occurs in some low-grade protective film products because the protective film is combined with the protected profile. There is a suitable environment such as sunshine and water, and there is a kind of chemical cooperation. There is no good way to avoid this kind of cooperation, because its reproduction is not regular, so there is no such problem at present. A good way to avoid being born!

      It is difficult to peel off the protective film product. When the profile product is finished and peeled off, the protective film cannot be effectively peeled off. There are two reasons for the reason. First, the sensitive adhesive used for the protective film product is not a special adhesive for the protective film. If so, The protective film is of course very effective when applied, but it is very difficult to peel off. This is also the most common problem with protective films produced by some illegal protective film manufacturers. Another possibility is to protect the film. The material used in the belt is too soft to withstand the pulling force at the time of peeling, and breakage occurs during peeling, which is a problem that is very headache for the user.

      The protective film performs well in the middle after a period of use, but the wings are raised at both ends. The main reason for this phenomenon is that the protective film is stretched more during the pasting process with the protected profile. In the high temperature environment, there is an unnecessary retraction phenomenon. This problem occurs mostly in the products of southern customers. Therefore, the protective film should pay attention to the influence of the environmental temperature difference on the use of the product during the production process, and avoid unnecessary in the pasting process. Surface stretching.

      It can be said that the huge demand for industrialization is the source of the development of the protective film company, and the development of the protective film industry will continue to move forward steadily.
