Q:What to do if the protective film on aluminium alloy is very difficult to remove?
Use sulfuric acid.
Q:why do some marks appear on the suface after PC+ABS specular products are coated with protective films?
The phenomenon occurs because film is covered unevenly when some parts are perfectly coated but others are not. In such a condition, the PC+ABS material changes as the temperature and humidity change, forming bubbles. Of course, there's something to do with the glue of the protective film. If highly required, protective film must use specific glue.
Q:How to cover the screen with protective film? What tools and skills are needed?
1. Wipe away the dust on the surface of the screen with the fibrous cloth attached at first. When you wipe the screen, you should wipe in the same direction. Don't do it back and forth. 2. Then determine the direction in which you will stick the film. And peel down a small part of the release film marked as "step1" and get ready to stick it. 3. When you stick the film, you should peel down a part of the release film and align it at the screen. Then stick it to the screen and tear the release film at the same time until the whole film is sticked to the screen. 4. When it's done, tear off the second layer of release film marked as "Step2" . 5. Finally completely tear off "Step2" release film. Then you can use it without worry.
Q:What's the function of the protective film coated on cup lid?
It's used to prevent the lid from scratches during delivery. It is not necessary to pay attention to these details.
Q:What's the difference between radiation and static? How can I know the protective film is anti-static or not? What harm can static do?
Radiation is a kind of wave with penetrability. Any heat source generates radiation to some extent, strong or weak. Radiation is harmful to human body. Display, keyboard and mouse generate radiation, though very little. There's no problem if you don't use them for too long. But if it's nuclear radiation, it will damage human body very badly, even cause death. Static is a kind of phenomenon that occur because of electrostatic force generated by the interaction of point charges. Static can be generaed by friction. It may happen when screen is used for a long time. Static itselt does no harm to human body. But if your hands is static, when you touch precise instruments, the instruments may be damaged. That's because static can produce little sparks that may cause fire if there's something inflammable. The static on screen can be eliminated by wiping with damp towel. Protecive film separates the screen and electrons. Thus it's anti-static.
Q:What kind of material is acrylic protective film made from?
Acrylic protective film can be made from PE materials, PET materials and OPP materials, etc. The materials are the materials used in base film of the protective film. And acrylic is a kind of glue.
Q:What to do when the protective film on plastic steel window is useless and difficult to remove?
You can buy a bottle of xylene solvent from building materials stores to clean it out. Be careful that the solvent is volatile and toxic. Notice to ventilate when using it.
Q:What is the difference between the three-layered anti-static protective film and ordinary film?
The differences between three-layered anti-static protective film and ordinary film? It's simple! 1. To figure out whether the three-layered anti-static protective film and ordinary film are made from PET materials. 2. The three-layered anti-static protective film uses PET sandwich structure which means the middle layer is PET anti-static film and the other two layers are protective film to protect the middle layer of film. At present, this kind of film is usually used to prevent scratches. The anti-static function is produced by silica gel. 3. Ordinary film is not anti-scratch. And it is probably covered with glue.
Q:The color of the aluminium-plastic panel is white without protective film. But I've seen other colors that looks like it's painted.
This shows that the quality of the coating of the aluminium-plastic panel you bought is not good. The paint on the surface of the panel should be very even and consistent. There shouldn't be any dark stripe or marks or shades of the same color which usually appear in spraying processing.
Q:Can non-sticky table tennis racket be coated with protective film?
This is a very simple method. But I assure you it works. Use damp towel to wipe the bat to clean it. And then coat it with protective film when it's still damp.
