Q:Is original iPad coated with a protective film?
No. There's almost nothing complimentary with original iPad.
Q:Bad smell generated from the electric baking pan after its protective film is destroyed. Is the pan still usable?
The smell is toxic. The non-stick interior coating is destroyed. I was told that things like is unusable soon or later. You'd better replace it as early as possible. It's destroyed by the spatulas.
Q:How to distinguish the adhesion degrees of Protective film materials?
It depends on what exact kind of product the customer want. Certain product has certain function and degree of adhesion. 1N or less refers to low degree of adhesion; 1-3N refers to medium degree, and 3N or more, high degree. In addition, there are also slight degree and super degree somewhere.
Q:What are the differences between a LCD protective film for laptop and a protective film for mobile phone ?
The functions of a laptop LCD protective film: 1. Ordinary films: Ordinary films only protect the screen from dust and scratch. This kind of films is commonly used and classified into two types--scratch-resistant(a bit more expensive) and non-scratch-resistant. 2. Functional films: this kind of films has better properties of scratch-resistant properties that can be classified into: A. Anti-reflection films, preventing the reflection of light on the screen, work well on some glossy display. Correspondingly they are more expensive than ordinary ones. B. Anti-ultraviolet-radiation films, protecting your eyes, have different technical content. This type of films is colored film --purple or green. But there's no need to mind the color because it's actually transparent when it cover the screen. The color a41 won't show up. And it won't affect the color displayed on the screen. C. Privacy-protective films. After coated with this kind of films, only looking at the screen head-on, or from no more than 30 degrees to sides, people can see the content shown on it clearly. And this kind of films is the most expensive among all.
Q:If the keyboard protective film is too big, do I need to cut it?
No need to cut it. You can just use the whole film to cover the keyboard.
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:PVC protective film reacted with the plastic on which it's coated. Why did that happen?
There's probably something to do with the plastic. After all, they are all chemicals.It's possible that reactions happen.
Q:What material is used for the adhesive film of the protective film on the aluminum plate?
The protective film on the aluminium plate is made of PE thin film. Specifically, the film is co-extruded by three layers of thin film. The film can be sticked to the aluminium plate to protect the surface of the aluminium plate from unexpected scratches and damage after it's covered with glue. If you want to learn more about PE protective film, you can go to the PP forum. There are many insiders who are specialized in this field.
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:The protective film on the surface of raw materials.
Generally speaking, the film is PE (polyethylene) film with single layer structure. It's transparent. Or it is two-layered with composite structure. One of the two layers is BOPP printing film. The other is PET film coated with aluminum. The two kinds of film mentioned above needs to be covered with a layer of PSA before it's used on profiles.If it's difficult to peel down from the profiles, it means the quality of the PSA is not good enough.
