Machining method for ground glass with gradual changing effect

Abstract

The invention discloses a machining method for ground glass with a gradual changing effect. The face not needing dull polish of a glass substrate is subjected to film covering protection, then, the glass substrate with film covering protection is subjected to gradual changing sand blasting, finally, the glass substrate with sand blasting is subjected to washing, sand grains for sand blasting are used for striking the face needing dull polishing of the glass substrate so that pits with corresponding sizes can be reserved in the stroke corresponding face of the glass substrate, and due to the fact that sand blasting is gradual sand blasting, the ground glass with the gradual changing effect can be obtained. Due to the fact that surplus materials on the glass substrate are removed in a sand blasting manner, compared with a traditional heating mold pressing method, the effect on the intensity of the glass substrate is relatively low, and the yield is greatly increased.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a method for processing frosted glass with gradient effects. Background technique [0002] At present, the back cover of many mobile phones is made of metal materials. Although it feels good, there are some insurmountable shortcomings: First, the metal will shield the mobile phone signal, which inevitably requires an injection molded antenna belt on the metal back cover. , to ensure normal communication, which will affect the integrity of the back cover; second, the metal material has low hardness and is not wear-resistant, and users are prone to scratches on the metal surface during use, which affects the appearance. Compared with metal, the glass material will not shield the signal, and the frosted glass can effectively avoid fingerprint residues during use, and the frosted glass is not easy to be scratched during use. At present, the communication speed is required to...

[0002] At present, the back cover of many mobile phones is made of metal materials. Although it feels good, there are some insurmountable shortcomings: First, the metal will shield the mobile phone signal, which inevitably requires an injection molded antenna belt on the metal back cover. , to ensure normal communication, which will affect the integrity of the back cover; second, the metal material has low hardness and is not wear-resistant, and users are prone to scratches on the metal surface during use, which affects the appearance

At present, the method of producing frosted glass with gradient effect mostly adopts the method of heating and applying mold pressure. This method is easy to deform the glass itself, and the yield rate is low.

[0003] In summary, how to solve the problem of low yield rate in the processing and production of frosted glass with gradient effect has become a technical problem to be solved urgently by those skilled in the art
