Abstract
The invention discloses a tempered glass thinning method. The method comprises the following steps: tempered glass to be treated is provided; acid-resisting printing ink is printed on one surface of the tempered glass; the tempered glass with the acid-resisting printing ink printed on the surface is subjected to heat treatment, such that the acid-resisting printing ink is cured into an acid-resisting protection layer attached to a surface of the tempered glass; the tempered glass with the acid-resisting protection layer attached to the surface is subjected to chemical acid thinning; when thinning is finished, the acid-resisting protection layer attached to the surface of the tempered glass is removed with a cleaning agent; and the tempered glass is washed and dried, such that the thinning process of the tempered glass is finished. With the tempered glass thinning method, operation can be carried out directly on a large sheet of tempered glass, and the large sheet of tempered glass does not need to be cut into small sheets. Compared to a traditional tempered glass thinning method, the tempered glass thinning method has the advantages of simple operation, high processing efficiency, and low processing cost.
