preparation example Construction

[0049] Also, see figure 1 , an embodiment of the present application also provides a method for preparing frosting etching solution, comprising the following steps:

[0050] S1: Weigh the raw materials of each formula component according to the formula of frosting etchant as mentioned above;

[0051] S2: Stir the ammonium bifluoride, other fluoride salts, sulfates and water in the formula components until fully blended to obtain the first mixed material;

[0052] S3: adding an alkaline pH regulator to the first mixture according to the pH value of the first mixture, stirring again until fully fused to obtain the second mixture;

[0053] S4: adding a sodium fluoride solution to the second mixed material, and aging to obtain a frosting etching solution.

[0054] see Figure 3 to Figure 5 After putting the glass into the frosting etchant provided in this embodiment, under the action of fluoride ions, sulfuric acid and ions, the surface of the glass can be corroded, frosted, an...

Embodiment 2

[0068] Weigh 12.5 parts of ammonium bifluoride, 4 parts of sodium fluoride solution, 2 parts of other fluoride salts, 5.5 parts of sulfate, 6.5 parts of alkaline pH regulator, and 7.5 parts of water; Stir salt, sulfate, and water until fully fused to obtain the first mixture; add an alkaline pH regulator to the first mixture according to the pH value of the first mixture, and stir again until fully fused to obtain the second mixture ; Add sodium fluoride solution to the second mixed material, and obtain frosting etching solution after aging.

[0069] Soak the glass in the frosting etching solution provided in this example for 60s-90s and then take it out. The surface of the obtained glass has a moderate frosting effect. It is measured that the haze of the glass is 30%-40%, and the light transmittance is 65%. % to 75%, the depth range of the microscopic concave spherical surface is 0.8 μm to 0.9 μm, and the width range is 10 μm to 12 μm.

[0070] Moreover, the steel ball drop ...

Abstract

The invention is applicable to the technical field of frosting etching, and provides a frosting etching solution and a preparation method and a use method thereof. The frosting etching solution comprises the following formula components in parts by mass: 10-15 parts of ammonium bifluoride, 3-5 parts of a sodium fluoride solution, 1-3 parts of other fluoride salts, 4-7 parts of sulfate, 5-8 parts of an alkaline pH regulator, and 6-9 parts of water. The frosting etching solution provided by the invention is strong in frosting etching capability, does not need to add an additional acidic pH regulator, and can be used for many times; glass treated by the frosting etching solution has a moderate frosting effect and has a diffuse reflection or light scattering function, so that the glare effect of an electronic screen or a lamp is reduced or avoided; the width value and the depth value of pits formed in the surface of the glass are both moderate, no burr feeling or rough feeling is generated, and the flash point effect is avoided; and the etched glass also has a visual effect similar to that of paper, accords with the watching habit of human eyes, and reduces visual fatigue.

Description

technical field [0001] The present application relates to the technical field of frost etching, in particular to a frost etching solution and its preparation method and use method. Background technique [0002] In the range observed by the human eye, when there is an extreme brightness contrast in space or time, it is easy to cause visual discomfort and reduce the ability of the human eye to observe, which is often called glare. High-intensity or long-lasting glare may cause psychological disgust, physical discomfort, and even temporary or permanent loss of vision. Devices are often equipped with anti-glare structures or programs. [0003] For the anti-glare cover used by the display screen, the traditional solution discloses a solution for treating the surface of the anti-glare cover so that the original plane becomes a matte diffuse reflection surface, thereby playing the role of anti-glare. Frosted etching is one of the mainstream methods to obtain a matte diffuse refle...
