Problems solved by technology

[0004] However, there are too many factors in the etching process that will affect the manufacturing yield of ultra-thin glass. There are many conditions that are difficult to control in the etching solution, such as the disturbance of the etching solution, the spray pressure of the etching solution, the flow rate of the etching solution, and the temperature of the etching solution, etc. Wait
[0005] For example, when the conditions of the above-mentioned etching...

specific Embodiment approach

[0021] First, in step S100 , at least one glass 10 is provided. Generally, the thickness of the glass 10 is about greater than 1.5 millimeters (millimeter; mm).

[0022] In step S110, the glass 10 is fixed in a vertical standing state as shown in appendix 2. For example, the glass 10 is clamped by a jig to fix it in a vertical standing state.

[0023] In step S120 , an etching solution (not shown) is atomized to obtain an atomized etching solution 20 . The atomization method can be supersonic atomization, pressurized atomization or vortex atomization.

[0024] Supersonic atomization is to spray the etchant into a spray after supersonic jet. Pressurized atomization is to pressurize the etchant to form a spray. Vortex atomization uses spoiler blades to rotate the etchant at high speed, and then sprays the etchant through a vortex chamber.

[0025] The etching solution contains at least hydrofluoric acid (HF), and hydrofluoric acid can also be used to prepare an appropriate ...

Abstract

A manufacturing method for ultrathin glass includes the following steps: providing at least one glass; fixing the glass in an upright standing state; atomizing an etching solution to obtain an atomized etching solution; and conveying the atomized etching solution to at least one nozzle of at least one liquid guiding tube through the at least one liquid guiding tube, and sprinkling the atomized etching solution onto the surface of the glass through the at least one nozzle. The flat ultrathin glass can be manufactured through the method.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a method for manufacturing ultra-thin glass. Background technique [0002] With the requirements of thin, light and small electronic products, such as handheld devices, the demand for ultra-thin glass is getting higher and higher. [0003] Because the thickness of ultra-thin glass is very small, it is not easy to manufacture. The current manufacturing method of ultra-thin glass is to perform a thinning process on a glass with a large thickness to make its thickness smaller, and the thinning process mainly uses Etching means to etch the thickness of the glass. [0004] However, there are too many factors in the etching process that will affect the manufacturing yield of ultra-thin glass. There are many conditions that are difficult to control in the etching solution, such as the disturbance of the etching solution, the spray pressure of the etching solution, the flow rate of the et...
