Problems solved by technology

After the cutting is completed, micro-cracks, chipping and edge chipping will inevitably occur on the edge of the tempered glass, resulting in a decrease in the compressive strength of the edge of the tempered glass

Embodiment Construction

[0019] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0020] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention discloses a method for cutting tempered glass. The method comprises the following steps of: providing a piece of tempered glass to be cut, covering acid-resisting protecting films on non-cut parts at the positive side and the back side of the tempered glass to be cut, subsequently spraying a chemical corrosive liquid to the positive side of the tempered glass to be cut, and carrying out chemical etching for 40-80 minutes so as to obtain cut tempered glass. According to the method for cutting the tempered glass, the tempered glass to be cut is cut by spraying the chemical corrosive liquid on the positive side and the back side of the tempered glass to be cut. Compared with the conventional method that the tempered glass is cut in a mechanical or laser mode, the method for cutting the tempered glass prevents the edge of the tempered glass from micro-crack, crack points and crack sides, so that the compressive strength of the edge of the tempered glass is not reduced.

Description

technical field [0001] The invention relates to the field of tempered glass processing, in particular to a method for cutting tempered glass. Background technique [0002] Traditional tempered glass cutting methods are mainly carried out in the form of mechanical physical cutting such as water jets, sand knives, and knife wheels, or laser cutting. After the cutting is completed, micro-cracks, chipping and edge chipping will inevitably occur on the edge of the tempered glass, resulting in a decrease in the compressive strength of the edge of the tempered glass. Contents of the invention [0003] Based on this, it is necessary to provide a cutting method of tempered glass that does not reduce the compressive strength of the edge of the tempered glass. [0004] A method for cutting tempered glass, comprising the steps of: [0005] Provide tempered glass to be cut; [0006] Cover the non-cutting parts of the front and back of the tempered glass to be cut with an acid-resist...
