Q:Why must the protective film on plastic steel window be torn off?
That's because it will be difficult to remove after the window is installed for too long. And the film affects the appearance of the window.
Q:What are the compositions of the protective film on aluminum alloy profile?
Acrylic acid PSA. It can be wiped off by lacquer thinner.
Q:what advantages does transparent DEL car protective film have?
Transparent DEL car protective film is a kind of high functional film with lightness, thinness, transparency and super toughness. It can effectively protect the car from scratching and striking of stones and sand. Perfectly attached to the surface of car paint, it can separete the paint from air, effectively and constantly protect the car from acid rain, oxidation and scratching. Besides, it can prevent excessive sun heat in an effective way, decreadsing the risk of spontaneous combustion. In addition, the film is transparent,which can constantly lighten the paint. And after the film is torn down, no glue marks will show on the surface and the original paint will stay undamaged and just the same as it was painted. What's more, it can save the waxing expense! And it's environmental friendly, causing no toxic and side effect to human bodies and pollution to the nature.
Q:Is there any skillful way to remove the protective film on aluminium-plastic panel?
Blowing it! Dismantling the panel to remove the film and installing it again is really troublesome! You can heat the film with high-power electric hair drier or fire. And then put somewhere cold to cool it down for a night. Then it will be easy to remove.
Q:What are the functions of pure gum protective film?
Insulation function.
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:How to prevent the protective film from damage and the stainless steel from marks when drawing the steel?
The surface quality of drawing dies of stainless steel is highly required. Rough surface can decrease friction and increase the property of adhesive resistance. Therefore, after the grinding processing, the more important work is to remove the processing marks left on the drawing dies. However, few people know the importance of the grinding and polishing processes when making dies. Throughout the whole process, the proportion of grinding and polishing processes should reach one third because the appearance quality of stainless steel products,to a large extent, is determined by the grinding and polishing techniques of making dies. The rougher the surface of dies is, the less it needs re-grinding. And the life of the dies also extends accordingly. If the surface of dies is not well grinded and polished, the marks on the drawn products will be clear. Although there's something to do with the fact that drawing stainless steel can easily cause seizing tumour, too. And to polish these marks takes time and the result is not good. Thus we should pay more attention to the grinding and polishing processes. Only when the surface processing precision of dies improves, can the marks decrease and the life of dies extend. In recent years, various new polishing techniques and polishing tools have arised at home. New processes and equipments such as ultrasonic polishing, electropolishing, abrasive jet and extrusion honing have been developed.
Q:Cover the surface of metal plate with protective film.
The film itself may be coated with a layer of glue. Thus it's no need to use other adhesive tapes. If you use double-sided adhesive tape, I recommmend this kind. This kind of tape won't fall off even if it ages owing to damp and high temperature. If the film feels not adhesive, it doesn't mean it's not coated with glue because generally, the adhesion of protective film is very low that you can hardly feel it.
Q:How to remove the protective film from the stainless steel thermos cup?
Rubbing it with sand.
Q:Is there any way to clean the protective film on standard door?
The simple way is to use an electric hair dryer to heat it, and then tear it off.
