specific Embodiment 1

[0021] Specific embodiment 1, comprising the following steps: Step A, carry out CNC processing and molding of the glass substrate, and cut into required size; Step B, put the processed glass substrate into an ultrasonic cleaning tank for the first cleaning, and the cleaning time is: 5 minutes, then put it into the etching tank and etch it with etchant, and then perform the second cleaning. The cleaning time is: 5 minutes, and finally dry it and strengthen it twice; The glass substrate is subjected to a light-sweeping treatment; step D, the glass substrate after the light-scanning is cleaned, and the glass substrate is soaked in a potassium nitrate tempering furnace at a temperature of 390° C. for 2.5 hours, and then cooled to room temperature within 1 hour.

specific Embodiment 2

[0022] The specific embodiment 2 includes the following steps: step A, carry out CNC processing and molding of the glass substrate, and cut it into the required size; step B, put the processed glass substrate into an ultrasonic cleaning tank for the first cleaning, and the cleaning time is: 3 minutes, then put it into the etching tank and etch it with an etchant, and then perform the second cleaning. The cleaning time is: 3 minutes, and finally dry it and strengthen it twice; The glass substrate is subjected to light-sweeping treatment; step D, clean the glass substrate after the light-scanning, and soak the glass substrate in a potassium nitrate tempering furnace at a temperature of 380° C. for 15 minutes, and then cool down to room temperature within 1 hour.

specific Embodiment 3

[0023] Specific embodiment three, comprising the following steps: step A, carry out CNC processing and molding of the glass substrate, and cut into required size; step B, put the processed glass substrate into an ultrasonic cleaning tank for the first cleaning, and the cleaning time is: 7 minutes, then put it into the etching tank and etch it with etchant, and then perform the second cleaning. The cleaning time is: 7 minutes, and finally dry it, and strengthen it twice; The glass substrate is subjected to light-sweeping treatment; step D, cleaning the glass substrate after the light-scanning, soaking the glass substrate in a potassium nitrate tempering furnace at a temperature of 400° C. for 1.5 hours, and then cooling down to room temperature within 1 hour.

[0024] It should be noted that the etchant is continuously supplied into the etching tank through a circulating pump, and the etchant is continuously supplied into the etching tank to ensure more sufficient and thorough e...

Abstract

The invention relates to a method for increasing the strength of ultra-thin glass. The method comprises the following steps: step A, carrying out CNC (Computer Numerical Control) processing molding ona glass substrate; step B, etching and thinning the processed glass substrate, and carrying out secondary reinforcement; step C, carrying out light sweeping treatment on the reinforced glass substrate through a glass light sweeping machine; step D, tempering the glass substrate after light sweeping. According to the technical scheme disclosed by the invention, the strength of the ultra-thin glassof which the thickness range is 0.10 to 0.33 mm can be increased, the requirement of existing mobile phone cover plate and a protective piece on strength can be met, and accident breakage during a dropping process of a mobile phone, a tablet PC (Personal Computer) and the like can be reduced, so that electronic products can be protected.

Description

technical field [0001] The invention relates to the technical field of strengthening glass strength, in particular to a method for improving the strength of ultra-thin glass. Background technique [0002] Ultra-thin glass is the trend of thinning and thinning global consumer electronics products. Thinning is just in the ascendant stage. The current development of this industry has the following characteristics: The trend of thinning and thinning is irreversible. It has also been used in smartphones and notebook computers. Gradually realize more ultra-thin applications, etc. With the maturation of related software and hardware industries and higher requirements for thinning applications, the technology of cover plates and protective sheets is also being promoted. However, ultra-thin glass is very easy to break and break, so it is imperative to improve the strength of ultra-thin glass. Contents of the invention [0003] The technical problem to be solved by the present inv...
