Problems solved by technology

The disadvantages of these anti-glare glasses are: the glass surface is not corrosion-resistant, the anti-scratch performance is poor, after a long time of use, it will wear and shine, the coating layer will fall off or change color, and many problems will affect the appearance of the product.
Not only the process steps are cumbersome, but the most important thing is that the frosting paste used in the etching in the technical solution can only achieve the roughening

Example Embodiment

[0020] The invention discloses a glass partial anti-glare processing technology, which comprises the following steps:

[0021] 1) Cover the part of the glass surface to be treated that does not need anti-glare treatment with an acid-resistant and impact-resistant protective layer;

[0022] 2) Sand blasting: Use compressed air to impact silicon carbide sand with a mesh size of 2000 or more to the glass surface not covered with an acid-resistant protective film. Insufficient glare accuracy.

[0023] 3) Etching: Put the sandblasted glass into a strong acid mixture with a concentration of 10% to 25% and etch for 25 to 30 minutes. The components and their proportions in the strong acid mixture are:

[0024] Hydrofluoric acid 90~91%

[0025] Sulfuric acid 2~3%

[0026] Hydrochloric acid 2~3%

[0027] Phosphoric acid 1~2%

[0028] Nitric acid 1~2%;

[0029] 4) Cleaning: Put the etched glass into the cleaning tank for cleaning, then remove the acid-resistant and impact-resistant...

Abstract

The invention discloses a locally anti-dazzle processing process of glass. The process comprises the following steps: firstly covering the part which does not need anti-dazzle treatment on the surface of to-be-treated glass with an acid-resistant impact-resistant protective layer; then impacting silicon carbide sands which are over 2000 meshes by using compressed air to the surface of the glass which is not covered by the acid-resistant impact-resistant protective layer, wherein the sand spray time is 30-60 minutes; and after sand spray, putting the sprayed glass into a 10-25% strong acid mixed solution to etch for 25-30 minutes. The process is simple to operate and refine in step and fully satisfies the technique requirements of optical level flat panel display and subtle touch of a touch screen.

Description

technical field [0001] The invention relates to a glass surface treatment process, in particular to a glass partial anti-glare processing process. Background technique [0002] In our daily life, we all have the experience of being attacked by dazzling glare, partly from the glare light source, and partly from the reflection of glare: for example, when we operate a computer, we often cannot see the displayed content clearly because of the reflection of the scenery outside the monitor on the monitor surface And trouble; another example is that a layer of cover glass will be added on many LCD screens for protection, and the surrounding edges of these cover glass will be exposed outside. Since the glass cover is processed by mechanical cutting and edging, the surrounding edges are very If it is smooth, the light on the display screen will shine through the edge of the glass to form a dazzling edge light line. These are all caused by light reflection on the glass surface. To r...
