Problems solved by technology

[0002] In the traditional tempered glass production process, high-temperature glaze needs to be screen-printed on the glass surface and then tempered or heated for sintering. However, due to the lack of corresponding breakthroughs in technology, this traditional sintering technology must place the glass in a high-temperature plate for sintering. However, this method can only be applied to glass with a large thickness, and if thin glass (1mm and below) is used, it will cause the glass to burst or deform, which cannot meet the demand
[0003] In addition, in order to make the surface of thin tempered glass have the effect of frosting, the traditional method is to use chemical etching method for processing, but the etching method is undoubtedly inefficient and seriously pollutes the environment, which cannot meet the demand

Embodiment

[0021] Embodiment: a kind of method for preparing tempered glass, it comprises the following steps:

[0022] (1) Pretreat the glass substrate to remove stains and impurities on the glass surface;

[0023] (2) Printing functional high-temperature glazes on the glass surface by using screen printing technology;

[0024] (3) Place the silk-screened glass in the heating furnace in such a way that the front and rear surfaces do not touch the heating furnace panel, and then raise the temperature of the heating furnace to 500°C and 500°C by 10°C for 10 minutes, and then keep it at the temperature for 3 Hour;

[0025] (4) Lower the temperature in the heating furnace to room temperature by 10°C for 10 minutes; then take out the glass;

[0026] (5) Process and shape the removed glass;

[0027] (6) Chemically temper the glass as a whole to obtain the final tempered glass.

[0028] The above method places the screen-printed glass in the heating furnace in such a way that the front and...

Abstract

The invention discloses a method for manufacturing tempered glass. The method is characterized by being processed in steps of defouling, bur picking, screen printing, sintering, heating, heat preserving, cooling, machine shaping and chemical tempering, and the glass well subjected to screen printing in the sintering step is placed in a heating furnace in a manner that front and rear surfaces are not exposed to heating-furnace panels. With the method, the situation that the surfaces of the tampered glass are exposed to the heating-furnace panels resulting in glass blowout or deformation due to temperature concentration in a traditional process is avoided, the glass can be heated evenly when sintered in the heating furnace by means of heating in suspension, and evenness in glass glazing is further improved.
