Q: How to cover the screen with protective film? What tools and skills are needed?
You need to prepare a knife with intact tip, a piece of clean cloth, a hard card like phone card or discount card, and electric hair drier. Firstly, wipe the screen with the clean cloth. Then peel the protective film and stick it to the screen from one side and press it with the card from that side at the same time. There will be no bubbles between the screen and the film this way. If the film curls, you can heat it with the electric hair drier and pull it at the same time.
Q: If a photo is covered with protective film, can I still develop the photo?
Yes, you can.
Q: How to clean up the protective film on plastic steel doors and windows?
Using alcohol
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.
Q: How long is the screen left on the screen of the mobile phone for a long time?
Just spray it on it. It's not worth any money. I don't think anyone else will want it. If you want to buy, you can sell the phone accessories to the place, 10 yuan OK.
Q: what are the features of AR protective film? What are the differences between it and other protective films?
Protective film made from AR material is the best protective film on the market at present. AR material is a kind of synthetic material, generally composed of three layers: silica gel as the adsorbed layer, PET as the interlayer and outer layer as the special processing layer. And the special processing layer can be further classified into AG processing layer and HC processing layer. AG processing refers to Anti-Glare processing which is used in matte protective film. HC processing is Hard Coating processing, used in protective film with high light transmittance. AR protective film features the effect of non-reflective screen and high light transmittance which exerts no affect on the display of screen. Besides, the surface is specially treated to soften it and make it scratch-resistant and friction-resistant. No scratch leaves on it even after a long time of using. The chemical material silica gel is used as binder to stick the film to the screen without damaging the screen and marks left on it. What's more, it is washable and reusable. At present, it has become the major research object of some famous manufacturers of protective films like OK8 and BENKS. It's easy to buy on the market. But it's more expensive than that made from PET material.
Q: What properties does the glue on the glass protective film have? Why doesn't its adhesion change when it meets water?
Usually the glue on the glass protective film is acrylic adhesive. Its adhesion will be badly affected when it's exposed to water for a long time.
Q: What materials is rotective film made from?
PP material: material used in plastic bags that we often use. The chemical name of PP is polypropylene. PVC material: PVC material is more thick but its light transmittance is not good. PET material: the chemical name of the film made from this kind of material is polyester thin film. AR material: AR is a kind of synthetic material, generally composed of three layers--the silica gel as the adsorptive layer, PET as the middle layer and outer layer as the special processed layer. Special processings usually can be divided into two kinds-- AG processing and HC processing. AG processing is anti-glare processing, adopted when making matte protective film. HC processing is hard coating processing, used on protective film of high light transmittance.
Q: What's the reason why watermarks are easy to appear on protective film of high adhesion?
NOTE: Standard protective film is anti-static. You can't feel it adhesive by hands. It's the only choice of high-class digital camera and digital vidicon. Some protective films on the market is very sticky because it's just a layer of plastic film coated with glue. There may be bubbles or watermarks on the screen after you cover it on the screen. The display effect will be very bad. And this kind of film is very difficult to remove. It's even more difficult to clean up the glue. Remember it: if you really cherish your cell phone, digital camera or digital vidicon,NEVER use this kind of film on it!
Q: How many times do you wash your face? What about the damage to the protective film?
Even oily skin, the number of times a day wash your face should not exceed 3 times. Excessive cleansing can easily destroy the natural protective film that forms on the surface of the skin. The skin secretes more oil to protect itself, and the face becomes more oily
