Q:What can the PET protective film be used for?
PET materials are non-toxic and non-odorous materials, featuring light weight, high strength, good transparency and resistance, etc.
Q:What does thickness C of the base material of protective film stand for?
It's just a terminology about thickness in industry. 5 c = 50 um = 0.05 mm.
Q:How to clean up the protective film on plastic steel doors and windows?
Using alcohol
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:What are the genaral standards of protective film teat?
There are only some general conventions in the industry. No national standards at present.
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:What are the functions of pure gum protective film?
Insulation, or support.
Q:Some questions about protective film for ping pong bat gum.
Yes, you can.
Q:What's the best way to clean the glue of protective film which is coated on the elevator door? And the fastest way?
You can try some essential balm.
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.
