Coated tempered glass and production process thereof

Abstract

The invention relates to coated tempered glass and a production process thereof, and relates to the field of tempered glass, in order to solve the problem that the coating effect of the tempered glass is affected due to the fact that coating liquid is not evenly covered, and the production process of the coated tempered glass comprises the following steps that firstly, a raw glass sheet is cleaned, the raw glass sheets are cleaned and dried in the conveying process; step 2, rubbing the raw glass sheet: rubbing the upper surface of the raw glass sheet with silk to enable the upper surface of the raw glass sheet to have positive ions; 3, coating liquid spraying: spraying the coating liquid through a spraying device, generating negative ions through a negative ion generator, and combining the negative ions with the atomized coating liquid, so that the atomized coating liquid can be quickly adhered to the upper surface of the original glass sheet; and 4, forging the raw glass sheet: feeding the raw glass sheet into a toughening furnace for forging. According to the application, the film coating efficiency is improved, and the film coating liquid is uniformly laid, so that the film coating effect of the tempered glass is improved.

Description

technical field [0001] The present application relates to the field of tempered glass, in particular to a coated tempered glass and a production process thereof. Background technique [0002] In order to improve the strength of the glass, compressive stress is formed on the surface of the glass to enhance the glass's own wind pressure resistance, cold and heat resistance, impact resistance, etc. This kind of glass is called tempered glass. In order to change the optical properties of the glass, it is often placed on one side of the tempered glass. Surface coating, coating is to coat one or more layers of metal, alloy or metal compound film on the surface of tempered glass. [0003] During the production of the existing tempered glass, the surface of the original glass sheet is first cleaned, and then the coating liquid is sprayed on the surface of the original glass sheet, and then the original glass sheet is sent into the tempering furnace for forging. After the change occ...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventors have found that there are following defects: the coating solution is covered on the surface of the original glass sheet by spraying, and the coating solution will be atomized during spraying, and the original glass sheet is less attractive to the coating solution. When the air flows, it drives the atomized coating solution to flow, resulting in uneven coverage of the coating solution on the original glass sheet, thus affecting the coating effect of tempered glass
