Abstract

The invention discloses a reinforcing method for plate glass. The reinforcing method comprises the following steps of: providing the plate glass; and illuminating the edge of the plate glass by utilizing laser emitted by a laser emitter, fusing the edge of the plate glass, and then quickly cooling the plate glass by utilizing a cooling agent, so as to finish the reinforcing of the plate glass. According to the reinforcing method for the plate glass, the laser is utilized to illuminate the edge of the plate glass, so that the edge of the plate glass is fused, and micro-cracks, collapse points and collapse sides generated at the edge of the plate glass are eliminated; and HF (hydrogen fluoride) is not used in the reinforcing method, so that the pollution is relatively low.

Description

technical field [0001] The invention relates to the field of flat glass, in particular to a method for strengthening flat glass. Background technique [0002] Flat glass, especially flat glass used in LCD, TP, CG and other fine glass fields, requires high compressive strength in order to meet the needs of the application. [0003] In the field of flat glass, after the large piece of glass is prepared, it needs to be cut into flat glass of suitable size. When cutting, it will inevitably lead to micro-cracks, chipping and edge chipping on the edge of the flat glass, which will lead to a decrease in the compressive strength of the flat glass. Therefore, it is necessary to strengthen the cut flat glass. [0004] The traditional method of strengthening flat glass is to protect the upper and lower sides of the flat glass with an acid-resistant film, and to perform HF corrosion on the edge of the flat glass, thereby eliminating microcracks, chipping and chipping on the edge of the...
