Selection Elements of PE Protective Film and Adhesive Synthesis Technology

PE protective film has brought us a lot of convenience in our daily life, especially in the production, manufacturing, transportation, and storage aspects. PE protective film can ensure that goods are not contaminated and corroded, and that the surface of the product has good smoothness. It can also significantly improve the product's market competitiveness. When purchasing PE protective film, what should we pay attention to
1、 Observing the passability of PE protective film: It is difficult for the human eye to observe this aspect of PE protective film. It is better to use optical instruments for measurement, or cut the protective film into small pieces and place them on the desktop of the computer. Then, create a Word file on the computer and paste the protective film on the computer screen according to the document to check the passability.
2、 Check the haze of PE protective film: First, turn off the screen attached to the PE protective film, and then apply different protective films in order. If the background color of the screen is more prominent, it means the haze is lower. The lower the haze, the higher the quality of the material. This method is more suitable for black test boards, and it is easy to distinguish the differences.
3、 Check the static electricity of PE protective film: Due to the fact that LCD screens are generally particularly sensitive and afraid of static electricity, it is better to stick PE protective film as small as possible on static electricity. Tear some small pieces of paper on the desktop and remove the protective film. Place the protective film directly near the paper and observe the results. If it is directly adsorbed, it indicates that there is static electricity.
Protective film/tape adhesive is made of natural materials or synthetic polymers, and acrylic adhesive is a typical synthetic adhesive.
Acrylic adhesive raw materials.
The raw material used in acrylic adhesives is acrylic monomers, which are also used in contact lenses, plastic glass, and water absorbing polymers. By selecting and polymerizing these acrylic monomers, acrylic polymers with certain functions can be synthesized and used as protective film/tape adhesives. Acrylic adhesives are widely used in LCD panels due to their excellent transparency, weather resistance, heat resistance, and chemical resistance, In the manufacturing of mobile phones and cars.
Synthesis of acrylic adhesive.
There are three methods to synthesize acrylic polymers: solution polymerization, lotion polymerization and UV polymerization. In recent years, with the increasing awareness of global environmental protection, lotion polymerization and UV polymerization have become more and more popular, because these two methods do not require the use of organic solvents. The following shows various methods to synthesize acrylic polymers and their corresponding advantages and disadvantages.
