Abstract

The invention relates to the technical field of electronic glass processing, in particular to a method for improving an electronic glass reinforced size expansion phenomenon and a preparation method of reinforced glass. The method for improving the electronic glass strengthening size expansion phenomenon comprises the following steps of preparing a molten salt, and enabling the pH value of the molten salt to be smaller than 7; and carrying out chemical strengthening on the electronic glass to be strengthened in the molten salt. The phenomenon of electronic glass size expansion caused by chemical strengthening is fundamentally improved.

Description

technical field [0001] The invention relates to the technical field of electronic glass processing, in particular to a method for improving the size expansion phenomenon of electronic glass strengthening and a preparation method of strengthened glass. Background technique [0002] Electronic glass refers to a class of high-tech products that can be applied in the fields of electronics, microelectronics, and optoelectronics. It is mainly used for the production of integrated circuits and glass materials with functional components such as optoelectronics, thermoelectrics, acousto-optics, and magneto-optics. Its thickness is generally 0.1 ~ 2mm, and its size is one of its important parameters. [0003] The processing flow of electronic glass is: material cutting-CNC-polishing-cleaning-strengthening (tempering)-silk printing-coating, however, when chemical strengthening is carried out by traditional techniques, electronic glass generally suffers from dimensional expansion. In o...
