Description

Technical Field

[0001] The invention relates to the technical field of anti-glare glass production, and in particular to a production process of high-efficiency anti-glare glass. Background Art

[0002] Among the light entering the human eye, blue light and ultraviolet light are more harmful and are one of the main causes of glare. Therefore, anti-glare glass came into being. Anti-glare glass, referred to as AG glass, is a glass with a special surface treatment. The principle is to process one or both sides of the glass to make it have a lower reflectivity than ordinary glass, thereby reducing the interference of ambient light and reducing the occurrence of glare.

[0003] In the prior art, the production of anti-glare glass is mostly carried out by spraying, etching, sandblasting, coating and laminating. Spraying anti-glare glass is to form a layer of uniformly dispersed nano-scale silica particle suspension on the glass surface by spraying, and then adhere to the glass surface after heat treatment to accumulate into an uneven film layer. Etching anti-glare glass is to dissolve the silicon and oxygen on the surface of the glass with hydrofluoric acid, and obtain a glossy surface or a matte surface according to the solubility of the residual salts.

[0004] The present application aims to improve the problems of low etching rate of glass frosting liquid, poor etching uniformity, uneven surface, poor anti-glare effect, and difficulty in removing impurities on the glass surface during the actual production process of etched anti-glare glass, and provides a production process for efficient anti-glare glass to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a production process for efficient anti-glare glass to solve the problems of low etching rate of glass frosting liquid, poor etching uniformity, uneven surface, poor anti-glare effect and difficulty in removing impurities on the glass surface in the actual production process of the existing etched anti-glare glass.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A production process of high-efficiency anti-glare glass, comprising the following steps: original sheet cutting → primary cleaning → film application → frosting → polishing → secondary cleaning → film tearing → tertiary cleaning → inspection → flat packing;

[0008] The specific process of the original sheet cutting is: using a cutting machine to cut the glass original sheet into required specifications and sizes;

[0009] The specific process of the first cleaning is: using clean water to clean the cut glass to remove dust, impurities and dirt on the surface of the glass;

[0010] The specific process of film laminating is: using a film to laminating the non-frosted surface of the glass to protect the non-frosted surface from being affected by the frosting liquid and the frosting operation;

[0011] The specific frosting process is as follows: immersing the glass in the frosting liquid for etching, so that the glass and the frosting liquid are fully immersed and reacted, and finally the desired frosting effect is obtained;

[0012] The specific polishing process is as follows: putting the frosted glass into the polishing liquid for liquid polishing, and adjusting the concentration and rate of the polishing liquid to achieve the purpose of polishing the glass surface;

[0013] The specific process of the secondary cleaning is: washing the frosted surface of the glass with 3% to 8% hydrochloric acid to remove the frosting liquid residue on the glass surface, and then washing the glass with clean water to remove dust, impurities and dirt on the glass surface;

[0014] The specific process of film peeling is as follows: using an automatic film peeling machine to remove the film on the non-frosted surface of the glass;

[0015] The specific process of the three cleanings is: using clean water to clean the frosted and film-removed glass to remove stains and impurities on the glass surface;

[0016] The specific inspection process is as follows: inspect the frosted glass to determine whether the product quality is qualified;

[0017] The specific process of finished product packaging is as follows: the glass that has been frosted and inspected and passed the test is the finished product and can be packaged.

[0018] In some examples, the film used for the film is made of PVC material.

[0019] In some examples, the frosting liquid is a mixture of hydrofluoric acid, sulfuric acid, nitric acid, oxalic acid, ammonium chloride and water, and the specific ratio of the frosting liquid is: by mass percentage, hydrofluoric acid 10% to 20%, sulfuric acid 10% to 15%, nitric acid 10% to 15%, oxalic acid 8% to 15%, ammonium chloride 10% to 25%, and water 40% to 60%.

[0020] In some examples, the polishing liquid is a mixture of hydrofluoric acid, ammonium bifluoride, an organic acid and water, and the specific ratio of the polishing liquid is: 8% to 15% hydrofluoric acid, 5% to 15% ammonium bifluoride, 5% to 20% organic acid, and 50% to 80% water by mass.

[0021] In some examples, the organic acid is one of carboxylic acid, sulfonic acid and sulfinic acid.

[0022] In some examples, the liquid temperature of the frosting liquid is controlled at 45° C.-60° C., the liquid temperature of the polishing liquid is controlled at 30° C.-50° C., and the polishing rate is controlled at 2000 r / min-5000 r / min.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] 1. The production process of this high-efficiency anti-glare glass uses frosting liquid to etch the glass during the glass frosting process, and uses polishing liquid to liquid-polish the surface of the glass. By adjusting and using the composition, specific gravity and temperature of the frosting liquid and polishing liquid, the glass surface can achieve the desired frosting effect and the anti-glare purpose.

[0025] 2. The production process of this high-efficiency anti-glare glass aims to solve the problems of low etching rate, poor etching uniformity, uneven surface, poor anti-glare effect, etc. in traditional glass frosting liquid. In this glass frosting process, hydrofluoric acid, sulfuric acid, nitric acid, oxalic acid, and ammonium chloride are added to the frosting liquid, and the liquid temperature of the frosting liquid is controlled at 45°C-60°C, thereby increasing the rate and uniformity of glass frosting and improving the anti-glare effect of the glass. In addition, the frosting liquid components are easier to obtain, the cost is lower, and the economic benefits are better.

[0026] 3. The production process of this high-efficiency anti-glare glass adds hydrofluoric acid, ammonium bifluoride, and organic acid to the polishing liquid, and the temperature is controlled at 30℃-50℃. It can effectively remove impurities on the glass surface, reduce the unevenness of the glass surface, and make the glass surface smooth, thereby achieving the purpose of glass polishing. It also makes the etched glass more resistant to bending, and the polishing liquid is easier to obtain, the cost is lower, and the economic benefits are better. BRIEF DESCRIPTION OF THE DRAWINGS
