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.

For the ease of understanding the present invention, the below is described more fully the present invention with reference to relevant drawings.Provided preferred embodiment of the present invention in the accompanying drawing.But the present invention can realize with many different forms, be not limited to embodiment described herein.On the contrary, provide the purpose of these embodiment be make the understanding of disclosure of the present invention more comprehensively thorough.
Need to prove that when element is called as " being fixed in " another element, can directly can there be element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be to be directly connected to another element or may to have simultaneously centering elements.Term as used herein " vertical ", " level ", " left side ", " right side " and similar statement are just for illustrative purposes.
Unless otherwise defined, the employed all technology of this paper are identical with the implication that belongs to the common understanding of those skilled in the art of the present invention with scientific terminology.Employed term is not intended to be restriction the present invention just in order to describe the purpose of specific embodiment in specification sheets of the present invention herein.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.
As depicted in figs. 1 and 2, the cutting method of the toughened glass of an embodiment comprises the steps:
S10, provide toughened glass 10 to be cut.
Toughened glass 10 to be cut can be common soda-lime glass or aluminosilicate glass etc., and thickness can be 0.1mm～1.5mm.
S20, cover acidproof protective membrane at the non-cutting part of the pros and cons of toughened glass to be cut 10, then chemical corrosion liquid is sprayed onto the pros and cons of toughened glass to be cut 10, behind chemical etching 40min～80min, obtain the toughened glass of well cutting.
In the present embodiment, the material of acidproof protective membrane is acid-proof resin.
The time of chemical etching and temperature can be carried out suitable change according to glass ingredient and thickness thereof, generally select to process 40min～80min under the normal temperature
In the present embodiment, described chemical corrosion liquid is the mixed acid solution that contains mass percent concentration 5%～40% hydrofluoric acid.The solute of hydrofluoric acid mixed acid solution comprises hydrofluoric acid, mineral acid and promoting agent, and wherein, the mass percentage concentration of hydrofluoric acid is 5%～40%.Mineral acid can be hydrochloric acid or nitric acid.
In the present embodiment, chemical corrosion liquid is sprayed onto in the operation of pros and cons of toughened glass 10 to be cut toughened glass 10 horizontal positioned to be cut.
Toughened glass 10 horizontal positioned to be cut can produce bubble and injection stream in chemical corrosion liquid, thereby accelerate chemical corrosion liquid the flowing of toughened glass to be cut 10 surfaces, and have reached the effect that very fast etching speed is finished cutting toughened glass 10 to be cut.
