Q:What to do if the adhesion of the PE protective film is too high?
Recently, the adhesion of PE protective film is determined by the thickness of slica gel. Not long ago, when making protective film for the screen of VDOO mobile phone, the company had the same problem. High adhesion means high thickness. When the whether is hot,the slica gel will expand when heated and contract when cooled making it look like the screen is sweating,which is call overflow for short in jargon. Therefore, make sure the adhesion is not too high, otherwise it will be difficult to tear the film down. The VDOO company did many experiments when designed the film and finally found the appropriate data of thickness. Besides, taking the thickness into consideration, the purposes of flatness, high resisitance to scratches and high clarity also achieved.
Q:How to remove the protective film on stainless steel?
Not to tear it down. Peel it off after it's heated by air heater and then wipe the surface of the stainless steel with a warm towel.
Q:How to remove the protective film on stainless steel door after using for a long time?
You can try some solvent like nitro thinners. But out of safety concerns, you can try to wipe a small certain area with hot water and washing powder at first.
Q:How to remove the protective film on PCM plate in a quick way?
PCM plate can be coated with film using machine. But you can only tear off the film by hands. There is no such machine that can remove the film for you.
Q:How about the electrostatic adsorptive function of PE protective film ?
1. Corona treatment is used in the process of the making of PE protective film, increasing the surface area of the film and making it static to meet the need of the following gluing. It's conducive to the combination of glue and film this way. 2. There's no such PE anti-static protective film with glue itself has adsorption function. Multi-layer film blowing machine can make such product at one time. Hualibao PE protective film features softness, good viscosity and easiness to stick and remove. And no glue remains after it's torn down.
Q:How to distinguish PET protective film from PE protective film?
Q:The ways to remove the protective film on household appliances
I suggest you not to use fire to burn it. You an use a piece of rough cloth or the cloth we use to do the dishes. If you are afraid to scratch the surface, you can slowly wipe it with some toothpaste. If wipe it using steel bush with water, the color of the metal surface may change.
Q:How to easily tear protective film down from the refrigerator?
Try to use electric hair drier at low gears to blow the film from a certain distance. When heated, the film will expand. It will make it easier to tear off the film.
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:If I have known about the thickness, length and the diameter of the core of a roll of protective film, how can you know the diameter of the roll of film?
The length equals 3.14 times the sum of the diameter of the whole roll and the diameter of the core. Or the length equals 2 times the difference between the diameter of the whole roll and the diameter of the core.
