Jin Jiuyuan teach you how to buy PE protective film
PE protective film in the production process is constantly improving, the scope of our use is also constantly increasing. Widely used in hardware industry, photoelectric industry, plastic industry, printing industry, wire and cable industry, electronic industry, mobile phone digital industry and so on. PE protective film is used so widely, so how to buy PE protective film, has become a top priority, today Jin Jiuyuan xiaobian sorted out five PE protective film skills, to share with you!
In recent years, a lot of products screen size is getting bigger and bigger, and more and more smart phones with capacitive screen (touch with fingers rather than the old resistance screen to scratch with a pen) application, PE protective film is more and more need to have anti-fingerprint function.
Look at the light penetration
This is difficult to identify with the naked eye, it is best to use optical instruments to determine, there is a simpler method, is to choose PE protective film respectively cut a small piece in the middle of the computer desktop one by one paste open, and then create a blank WORD document on the computer, Check the degree of whiteness (called brightness) of blank WORD documents with and without film or different film areas on the computer.
Due to the liquid crystal display is afraid of electrostatic sensitive device, electrostatic as small as possible when stick protective film, test method are all ready for the test of PE protective film (three layers or two layers of material), have a smoke to knock some cigarette ash on the desktop, or get some tiny confetti on the desktop, then tore to PE protective film on the top of a layer of protective film (for 3 layer material have this step). Then tear off the protective film of the silica gel layer, tear off this layer of PE protective film will immediately use the layer (silica gel surface) to close to soot or paper, to see whether the protective film will adsorb these things to the silicone layer of the protective film, whether the degree of adsorption is strong. The higher the intensity, the higher the static electricity generated by the material, the worse the material, and vice versa.
1, PE protective film is anti scratch, anti scratch is the most concerned about the problem, the current anti-scratch material on the market is basically similar (2-3H), the performance is also good, only anti scratch and not scratch. The test method is to use a pencil with hardness of 3H and push the PE protective film 10 times with strength of 500G at a 45 degree Angle. If there is no scratch, the hardness requirement of 3H can be reached.
2, there is a simple method, is to use a slightly hard metal device or newly cut nails on the PE protective film with the strength of the usual stylus scraping, such as very easy to scratch is identified as not scratch, no scratch can be determined to have anti-scratch function.
See the fog degree
1, PE protective film fog how to see it? First in the case of the monitor shut down to see, the method is the same as above, the protective film in turn, computer screen screen color is clear the fog is smaller, the fog is smaller the material is better, this method if the black test board is easier to see the difference.
2, in a dark room and open a fluorescent lamp, the PE protective film to tear in addition to the debonding membrane after living with your hands up and down in between the eyes and light, you carefully to see if there is a layer of mist evenly distributed within the PE protective film, that is the culprit, influence degree of fog the mist of something more serious, shows that the greater the fog, the material is the worse, Otherwise, the better; (Note that fog affects permeability, but it is a different concept from permeability!)
