Production method of tempered glass

Abstract

The invention relates to a production method of tempered glass. The production method includes the following steps of cutting a large piece of glass, and cutting out workblank demanded by production of the next working procedure; conducting cold treatment on the glass, cutting the workblank in demanded shapes, removing leftover materials of cut glass, and polishing the brims of the fractures of glass; bonding antireflection film to the surface layer of the glass subjected to the cold treatment; heating the glass for tempering, wherein a tempering oven is heated, the tempering temperature in the oven maintains at 650-670 DEG C, glass is conveyed into the tempering oven for heating and tempering through a transmission roller, and the heating time of every piece of glass with the thickness of1 mm is 40-45 seconds; conducting cooling on the glass, wherein the glass is conveyed out of the tempering oven and passes by an air grid, and shock cooling is carried out. In the tempering process of the tempered glass, the antireflection film and the glass are subjected to tempering at the appropriate temperature without generating wind spots, the surface of the antireflection film is correspondingly flat, the antireflection film is prevented from being singed or tempering of the glass is not complete, and the performance of the tempered glass is ensured.

Description

technical field [0001] The invention relates to the field of glass processing, in particular to a method for producing tempered glass. Background technique [0002] In our daily life, we all have the experience of being attacked by glare, partly from the glare light source, and partly from the reflection of glare; when we operate the computer, we often worry about the scenery outside the monitor. The reflection on the surface of the monitor makes it difficult to see the displayed content. ; Another example is that when we stop in front of the glass window to explore the scenery inside the window, the reflection of the glass surface often prevents you from clearly observing the scenery inside the window and so on. These are all caused by light reflection on the glass surface, because ordinary glass has high reflectivity. If you want to reduce the interference of ambient light, improve the viewing angle and brightness of the display screen, reduce the reflection of the screen...

Problems solved by technology

[0004] However, during the tempering process of tempered glass, especially when the tempered glass is tempered, the surface of the anti-reflection film contacts the roller table that conveys the glass, and is squeezed by the roller table, which will form wind spots on the surface of the anti-reflection film, resulting in The glass surface is uneven, which reduces the clarity of the glass and affects the anti-reflection performance of the glass
