Q:How to remove the protective film on elevator?
Do NOT use electric hair drier! It will make it more difficult to remove! Is the elevator made of stainless steel? If it is, you'd better find someone professional in this field to help you remove the film! They have their ways! It will make more difficult to remove.
Q:What's difference between iron rust and protective film of aluminum?
The iron rust is red. Aluminium is ligher than iron but it's easy to react with salt and vinegar and separate out toxin.
Q:How to clean up the protective film on plastic steel doors and windows?
You can clean it up with diluents, ethyl alcohol or rosin water which are sold in paint stores. But these solvents all affect the properties of profiles, the latter one in particular. I suggest you not use it too much.
Q:Does it matter if the protecive film on the cooling fin of air conditioning is washed off?
If the film is coated on the surface, that's hydrophilic film, used to strengthen the refrigerating effect. If it's removed when it should not be removed, then it will affect the refrigerating effect of the air conditioning. If there's a liite part of the film is washed off, it doesn't matter. But the fin is put closely to each other. You should remove the film one by one. Is the fin put closely to each other?
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 test the adhesion of protective film?
There's a special equipment for tension testing! The protective film you are saying may be silicone PET, generally having adhesion of 2 g - 10 g. High-quality ones have excellet performence in eliminating bubbles.
Q:What are the differences between PE protective film and PE release film?
PE protective film is used for the primary protection of electronic products when they leave the factory while PE release film is used as disposable consumable to protect the raw materials when wastes is discharged during processing.
Q:The technical issues of the cutting PE protective film
It's about the cutter. Maybe the position of cutter is too low. Sometimes, if the cutter ring is not smooth enough, the same problem may occur. Besides, for better result, you should also ensure that the cutter is pressed to the right position and no indentation on the blade.
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:How many labels are there on tempered film? I mean the things that should be torn off when using the film.
There's a piece of film on each side of tempered film. One is adhesive, and the other is unadhesive. Peel off the adhesive film and stick the tempered film to the screen. And get rid of the bubbles at the same time. when there's no bubbles, peel off te other film. And it's done! Hope it can help you!
