保护膜的透明性及选型要求保护膜在进行使用的过程中，其涂胶膜粘着剂的种类

The transparency and selection of the <br>protective film require that the protective film adhesives include solvent-based rubber adhesives, solvent-based acrylic adhesives, water-based acrylic adhesives, and silicone adhesives during the use of the protective film. Among them, water-based acrylic adhesives are commonly used in such products, which can easily adjust the adhesion, and have good transparency and weather resistance. <br>The protective film is generally produced by co-extrusion, and the self-adhesive layer is generally dominated by EVA, ultra-low density polyethylene or polyolefin plastomer resin, and this structure form has gradually become the mainstream of the market because it is more glued The film has many advantages, such as no residual glue, provides stable adhesion, reduces user costs, and creates higher profits for protective film manufacturers. <br>The protective film must first be viewed when the display is turned off. The method is the same as above. After attaching each protective film in sequence, the more the background color of the screen is, the smaller the haze is. The smaller the haze is, the better the material is. It is easier to see the difference with the black test board. <br>Another way to protect the film is to turn on a fluorescent lamp in a slightly dark room, remove the protective film from the upper and lower release films, hold it between your eyes and the light with your hands, and carefully see if there is a layer of fog Evenly distributed in the protective film, it is the culprit that affects the haze. The more serious this kind of fog, the greater the haze, the worse the material, and the better the contrary, (note that haze will affect the permeability rate, but Transmittance is two different concepts!) <br>Protective film Since the liquid crystal display is a sensitive device that is afraid of static electricity, the smaller the static electricity when the protective film is attached, the better. The test method is to prepare the protective film to be tested (3 layers or two Layer material), smoke a cigarette, tap some soot on the table, or get some small paper scraps on the table, then tear off the protective film above the protective film (this step is for 3 layers of material), and then tear the tape Silicone protective film. When tearing off this protective film, immediately use the layer (silicone surface) close to soot or paper dust to see if the protective film will adsorb these things on the silicone layer of the protective film. . The stronger it is, the higher the static electricity generated by this material is, the worse the material is, and the better the opposite. <br>Selection of protective film <br>1. Different surfaces require different viscosities; <br>2. Different materials with the same similar surfaces may also require different viscosities;<br>3. The subsequent processing steps are the key to determining the viscosity. Subsequent processing generally includes bending, stamping, cutting, drilling, thermoforming, etc .; <br>4.

Principle of selection of protective film: full test.

Transparency and selection requirements for protective film<br>In the process of use of the protective film, the types of adhesive adhesives are solvent-based rubber adhesives, solvent-based acrylic adhesives, water-based acrylic adhesives, and silicone adhesives. In addition to the water-based acrylic adhesive is widely used in such products, it can easily adjust the adhesive, and transparency and weather resistance is good.<br>Protective film is generally produced in a co-squeezing manner, and its self-adhesive layer is generally EVA, ultra-low density polyethylene or polyolefin plastic body resin-based, this form of structure has gradually become the mainstream of the market, because it has more advantages than the coating film, such as no residual glue, provide stable adhesive, reduce user costs and create higher profits for the manufacturer of protective film.<br>The protective film first in the case of monitor shutdown, the method is the same, the protection film in turn after the release, the more the screen color of its fog is smaller, the smaller the fog, the better the description material, this method if the black test board is easier to see the difference.<br>There is also a way to protect the film is in a slightly darker room, open a fluorescent light, the protective film to tear off the upper and lower off the film hand to hold between the eyes and the light, you carefully see whether there is a layer of fog in the protective film evenly distributed, that is the impact of fog, the more serious the fog, the more serious the fog, the worse the material, the worse, (attention fog will affect the transmission rate, but with the two different concepts!<br>Protection film because the liquid crystal display is sensitive device afraid of static electricity, when the protective film static smaller the better, the test method is ready to be tested protective film (3 layers or two layers of material), smoke a cigarette to knock a cigarette ash on the desktop, or make a small piece of confetti on the desktop And then tear off the protective film above the protective film (for 3 layers of material has this step), and then tear the protective film with silicone layer, tear off this layer of protective film immediately will use the layer (silicone surface) to get close to soot or confetti, See if the protective film will adsorbed these things to the silicone layer of the protective film, the degree of adsorption is strong. The stronger the material, the higher the static electricity produced by the material, the worse the material, the better.<br>Selection of protective films<br>1, different surfaces need different viscosity;<br>2.

You should carefully see if there is a layer of fog like things evenly distributed in the protective film, which is the main cause of affecting the haze.

The test method is to prepare the protective film to be tested (3-layer material or 2-layer material), smoke a cigarette and knock the ash on the desktop, or make some small paper scraps on the desktop, and then tear off the protective film above the protective film (this step is for 3-layer material), and then tear the protective film with silica gel Remove the protective film, and immediately move the use layer (silica gel surface) near the soot or paper scraps, to see whether the protective film will absorb these things to the silica gel layer of the protective film, and whether the absorption degree is strong.
