Research Progress on Chemical Strengthening Technology of Glass

Abstract

Abstract: Chemical strengthening technology, also known as ion-exchange technology, is widely used in construction, transportation, and other fields. This technology involves the formation of a compressive stress layer on the surface of glass to improve the mechanical strength of glass. Changing the parameters of chemical strengthening process directly affects the properties of glass after chemical strengthening. The effects of the ion-exchange principle, glass composition, chemical strengthening temperature, chemical strengthening time, and molten salt composition on the chemical strengthening process were discussed. The advantages and disadvantages of the electric field-assisted chemical strengthening process and the chemical strengthening process without molten salt were briefly presented. The research progress on chemical strengthening technology at the domestic and international level was summarized, and the shortcomings of the existing chemical glass strengthening technology were highlighted, which provided a reference for the scientific research and development of chemical strengthening technology.

Key words: glass, chemical strengthening, ion-exchange, chemical strengthening technology in molten salt, chemical strengthening technology without molten salt, micro-crack
