Problems solved by technology

However, in the existing vacuum glass, the operation mode of vacuuming to form a protective layer will cause the glass to break. In addition, in the existing preparation process, in order to ensure a good vacuum degree of the vacuum glass, the glass substrate is vacuum-operated. Therefore, the stress value of the glass substrate is extremely high

Abstract

The invention belongs to the technical field of tempered glass manufacturing, and provides a vacuum tempered glass substrate processing technology. The invention provides a vacuum tempered glass substrate processing technology. The vacuum tempered glass substrate processing technology specifically comprises the steps of cutting, edge grinding, alcohol washing, acid treatment, strengthening treatment, film coating treatment, physical tempering treatment, air cooling forming and the like. The prepared vacuum tempered glass substrate is subjected to special chemical cesium-potassium dipping treatment, the ion exchange effect of sodium ions and cesium and potassium ions is enhanced, the fireproof performance of glass is guaranteed, meanwhile, the stress value of the glass substrate is remarkably increased, and the situation that a vacuum glass cavity bursts under the external atmospheric pressure is improved.

Description

technical field [0001] The invention relates to the technical field of vacuum tempered glass manufacturing, in particular to a vacuum tempered glass substrate processing technology. Background technique [0002] At present, the vacuum glass on the market is generally separated by two pieces of flat glass with a support, and the edge of the two pieces of flat glass is sealed and vacuumized to form a vacuum layer between the two glass products. Heat preservation, sound insulation and noise reduction, etc. However, in the existing vacuum glass, the operation mode of vacuuming to form a protective layer will cause the glass to break. In addition, in the existing preparation process, in order to ensure a good vacuum degree of the vacuum glass, the glass substrate is vacuum-operated. Therefore, the stress value of the glass substrate is extremely high. Therefore, in order to overcome the cracking or even self-explosion in the preparation of the vacuum layer of the glass substrat...
