Chemical etching process for preparing AG (anti-glare) glass

Abstract

The invention provides a chemical etching process for preparing AG (anti-glare) glass, which comprises the following steps: through relative movement of a smearing part arranged in a working space and glass placed in the working space, an acid etching liquid medicine on the smearing part seeps and is smeared on the surface of the glass, so that the adhesion process of the acid etching liquid medicine on the surface of the glass is completed; compared with a traditional spraying mode, the acid etching liquid medicine is applied in a smearing mode, the acid etching liquid medicine can be evenly attached to the surface of the glass, application is uniform, the adhesion degree of the acid etching liquid medicine is good, the consumption of the acid etching liquid medicine is small, material waste and environmental pollution caused by spraying volatilization in the past are avoided, and the acid etching liquid medicine is only attached to the smearing face and does not damage non-smearing faces; and therefore, a protective film does not need to be pasted on the glass in advance, manpower and material resources are greatly saved, a large amount of time is saved, and the working efficiency is greatly improved.

Description

【Technical field】 [0001] The invention relates to the technical field of glass surface treatment, in particular to a chemical etching process for preparing AG anti-glare glass. 【Background technique】 [0002] According to the characteristics of the glass, the glass includes AR anti-reflection and anti-reflection glass, AF anti-fingerprint glass and AG anti-glare glass. Anti-glare glass, also known as anti-reflective glass or non-reflective glass, is a kind of glass whose surface is specially treated. The principle is to process one or both sides of the glass. Compared with ordinary glass, it has a lower reflectance, reducing the reflectance of light to less than 1%, thereby reducing the interference of ambient light, improving the clarity, visibility and viewing angle of the picture, reducing the reflection of the screen, and making the image Clearer and more realistic, allowing viewers to enjoy better visual effects, suitable for various displays, protective screens, elect...

Problems solved by technology

It has some disadvantages. Most of the liquid medicine cannot penetrate into the cracks when spraying and participate in acid etching, but it just flows away in vain, causing a lot of waste. Although it is slightly acidic, the waste of materials caused by spraying and volatilization is also It will cause harm to the surrounding environment and the human body, and the place where the glass does not need to be acid-etched needs to be covered with a protective film first, otherwise it will cause damage to the glass and affect the quality of the glass. Therefore, it is necessary to apply a protective film to the glass in advance, and the technical requirements for the film are very high.
