Q: What are the differences between 360 degrees, 180 degrees and 60 degrees privacy-protective films~: The differences are: the light transmittance of 360 degrees privacy-protective film (about 60%) is lower than that of 180 degrees film (80%). And 360 degrees film protect privacy in all directions but 180 degrees film in only two directions. 60 degrees refer to the visual angel of the computer user, meaning to look at the screen from an angel of 30 degrees from right or left side to the center line of the screen.

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.

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: What harm can the resin used in protective film do?: Coating hard screen with protective film does have its advantages.But it also bring the trouble which is uneven heat dissipation as well as expansion when heated and contraction when cooled.

The hidden trouble of the computer to human health, in terms of radiation type, mainly refers to various radiation "pollution" including electromagnetic radiation from the computer at work (all kinds of electromagnetic radiation and electromagnetic wave, etc.), sound (noise), light (ultraviolet ray, infrared ray and visible light, etc.).
