In the chemical industry, the market for adhesive tapes, protective films, and stickers is rapidly expanding. Adhesive tapes, protective films, and stickers are widely used in electronics, mobile phones, optoelectronics, communication, packaging, construction, papermaking, aerospace, automotive, textile, metallurgy, mechanical manufacturing, medical industries, and more. At present, adhesive products in China are growing at a rate of over 13% per year, and have become one of the dynamic industry forces in China's chemical industry.
The bonding between the protective film and the protected product is not firm, and there is a phenomenon of detachment during transportation and use. The reason for this problem is exactly the opposite to the previous problem. The high possibility is that the viscosity of the sensitive adhesive used in the production of the protective film product is not enough. Another possibility is that the pressure of the molding machine used by the user during the molding process is not enough, or the surface of the profile is not clean, there is dust or paint, etc, Affected the adhesion effect of the sensitive adhesive! If this problem occurs, it is necessary to take targeted measures, replace the sensitive adhesive, increase the film pressure, or pay attention to effective cleaning of the surface of the profile during film application to avoid such problems.
Although protective film products can be effectively peeled off, there are still words indicating the performance of protective film on the surface of the profile. This problem often occurs on some low-level protective film products, because the protective film combines with the protected profile in a suitable environment such as sunlight and water, resulting in a combination effect. Currently, there is no good method to avoid this combination effect, as its reproduction has no regular pattern to be found, So currently, there is no good way to avoid this problem!
It is difficult to peel off protective film products. When the profile product is installed and peeled off, the protective film cannot be effectively peeled off. There are two possible reasons for this. Firstly, the sensitive adhesive used in the protective film product is not a special sensitive adhesive for the protective film. If this is the case, the protective film may have a very good effect when applied, but it will be very difficult to peel off, This is also the most common problem with protective films produced by some illegal manufacturers of protective film products. Another possibility is that the material used for the protective film mother belt is too soft to withstand the tension during peeling, resulting in breakage during peeling, which is a very headache for users.
After using the protective film for a period of time, it performs well in the middle, but the wings at both ends rise. The main reason for this phenomenon is that the protective film has a high degree of stretching during the bonding process with the protected profile. After bonding, there is unnecessary retraction phenomenon when encountering high temperature environments. This problem often occurs in products from customers in the south. Therefore, during the production process of the protective film, attention should be paid to the impact of environmental temperature difference on product use, Avoid unnecessary surface stretching during the pasting process.
It can be said that the huge demand for industrialization is the driving force behind the development of protective film companies, and the development of the protective film industry will continue to steadily move forward.
