Q:How to clean up the protective film on organic glass after it's used for a long time?
You can only slowly tear it off. There's no other good ways. Thinners or similar things will damage the glass.
Q:What is PVC protective film?
1. It has the property of highlight and high reflective which is commonly called the mirror effect. 2. It has resistance to acids and alkali as well as corrosion. And no residual glue remains when removing the film. Use: It can be widely used on the protection of stainless steel sheets as well as aluminium products and industrial products during processing. The scotch tapes hanging on the doors of many restaurants are also made from PVC materials which are generally called PVC films. We have many nice films of this type . And we assure you they are all of good quality and reasonable price.
Q:What's anti-blue-ray film used for?
It has function of anti-ultraviolet-rays that can reflect visible light of harmful rays of 380nm-420nm and short wave blue ray. It's 100% anti-ultraviolet-rays of UV400. It can protect the eyes in particular.
Q:Is it okay not to tear off the protective film on the mirror stainless steel during laser cutting? How about the effect?
Before laser cutting, the stainless steel must be covered with specific protective film. Ordinary film may curl or cause bubbles or even twine around the cutter head.

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.
