Abstract
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...
