Problems solved by technology

At present, only the infiltration amount of tin ions on the tin surface can be effectively reduced, but it cannot be avoided, so the warping problem of the float cover glass after chemical strengthening is also inevitable

Embodiment Construction

[0026] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only the parts related to the present invention are shown in the drawings but not all of them.

[0027] This embodiment provides a method for reducing warpage during chemical strengthening of glass, which can effectively reduce the warpage of glass 6 produced by the float method during chemical strengthening, and improve the qualified rate of glass 6 . The glass 6 produced in this embodiment is mainly used in consumer touch electronic products, such as 2D, 2.5D and 3D ultra-thin electronic glass 6 , etc., but is not limited to the above glass types. The method for reducing ...

Abstract

The invention relates to the technical field of manufacturing of float glass and discloses a method for reducing warping in chemical strengthening of glass and a jig for strengthening. According to the method for reducing warping in chemical strengthening of the glass, before chemical strengthening of the glass, the glass is flat placed, a tin surface of the glass faces downwards, and in the process of chemical strengthening of the glass, the temperature of ion exchange is set to be 380-450 DEG C. The jig for strengthening is applied to the method for reducing warping in chemical strengtheningof the glass and used for bearing the glass and making the glass flat placed. According to the method for reducing warping in chemical strengthening of the glass and the jig for strengthening, the value of warping generated by the float glass in the chemical strengthening process can be effectively reduced, and the qualification rate of the glass is increased.

Description

technical field [0001] The invention relates to the technical field of manufacture of float glass, in particular to a method for reducing warpage during chemical strengthening of glass and a fixture for strengthening. Background technique [0002] In recent years, chemically strengthened cover glass with high strength, scratch resistance, and impact resistance has been used to protect the display in mobile displays such as mobile phones and tablet computers, and flat-panel displays such as large LCD TVs. For the characteristics of chemically strengthened glass, surface compressive stress (CS), depth of stress layer (DoL), and bulk tensile stress (CT) are generally used as indexes. [0003] Since the glass is an amorphous solid, the general silicate glass is composed of the main network formed by the Si-O bond and the alkali metal and alkaline earth metal plasma in the network. This network is mainly composed of polyhedra containing oxygen ions, the center of which is occupi...
