Embodiment Construction

[0028] The technical solution in this application will be described below with reference to the accompanying drawings.

[0029] As a commonly used material, glass is widely used in various fields. With the development of smart terminals, more and more terminals choose to use glass as a casing material, for example, a mobile phone with a glass front screen and a rear cover. However, due to the relatively high brittleness of the glass, it is not resistant to falling and is easily broken, resulting in poor resistance to falling of the smart terminal, which affects the user experience.

[0030] The common modes of glass failure mainly include: edge micro-crack propagation, surface puncture and bending tensile stress cracking. At present, a variety of treatment methods have been adopted to solve the problem of high brittleness and breakage of glass. One such treatment is to chemically strengthen the machined glass and then etch it after chemical strengthening to increase the stre...

Abstract

The invention provides a glass strengthening method, and relates to the technical field of glass processing. The glass strengthening method comprises the following steps: corroding glass by adopting corrosive liquid to passivate micro-cracks of the glass; and carrying out chemical strengthening on the corroded glass to form a strengthening layer on the surface of the glass. According to the glassstrengthening method, corrosion strengthening is carried out before chemical strengthening, so that the strength of the glass can be effectively enhanced, and weakening of corrosion strengthening andeven counteracting of the strengthening effect of chemical strengthening are avoided.

Description

technical field [0001] The present application relates to the technical field of glass processing, and more specifically relates to a glass strengthening method. Background technique [0002] Due to its high hardness, scratch resistance, and good optical performance, glass is increasingly used in the front screen and back cover of mobile phones. Compared with the metal case, the glass case can realize the integration of the back and reduce the shielding effect on the signal. In addition, the glass back cover can realize a variety of colors, which greatly improves the appearance of the mobile phone. With the fifth generation (5 th generation, 5G) mobile communication technology and wireless charging technology, the use of glass as the front screen or back cover of mobile phones has become more and more popular. [0003] However, at the same time, due to the high brittleness of the glass material, it has the disadvantages of being not resistant to falling and easily broken....
