PE protective film optional elements and adhesive synthesis technology

PE protective film in our daily life, for us to bring more convenience, especially in the production and manufacturing and transportation storage level, PE protective film can ensure that the product is not polluted and etch, and ensure that the surface of the product has a good smoothness, but also the product in the market competitiveness of the significant improvement, the purchase of PE protective film when:

First, look at the passing degree of PE protective film: This observation of PE protective film is more difficult for our human eyes to see, it is best to use optical instruments to measure, or cut the protective film into small pieces, and then placed on the desktop of the computer, and then establish a word document on the computer, according to the document, the protective film is pasted on the computer screen, and the passing degree can be observed.

Second, look at the PE protective film in the fog: first close the screen with the PE protective film, and then paste the different protective films in accordance with the order, if the background color of the screen is more obvious, then it represents the lower the fog, the lower the fog indicates the higher quality of the material, this way is more suitable for the black test board, it is easy to distinguish the difference.

Third, look at the static electricity of PE protective film: because the LCD display screen is basically particularly sensitive, and more afraid of static electricity, so the paste PE protective film on static electricity as small as possible, tear a small piece of paper on the desktop, and remove the protective film, directly put the protective film close to the paper, and the result of observation, if it is directly adsorbed, then it means that it contains static electricity.

Protective film/tape adhesives are made from natural materials or synthetic polymers, and acrylic adhesives are a typical synthetic adhesive.

Acrylic adhesive material.

The raw material used in acrylic adhesives is acrylic monomer, acrylic monomer is also used in contact lenses, plastic glass and water absorbent polymers, by selecting and polymerizing these acrylic monomers, it is possible to synthesize acrylic polymers with certain functions and use them as protective film/tape adhesives, acrylic adhesives due to its excellent transparency, weather resistance, Heat and chemical resistance are widely used in the manufacture of LCD panels, mobile phones and automobiles.

Synthesis of acrylic adhesives.

There are 3 methods to synthesize acrylic polymers: solution polymerization, emulsion polymerization and UV polymerization, in recent years, with the enhancement of global environmental protection awareness, emulsion polymerization and UV polymerization methods have become more and more popular, because these two synthesis methods do not require the use of organic solvents, the following shows the various methods of synthesizing acrylic polymers and their corresponding advantages and disadvantages.
