Embodiment 1

[0025] Embodiment 1: To prepare a glass etching solution, first add 40 parts by weight of water into the liquid medicine pool, then add 25 parts by weight of ammonium bifluoride and 2 parts by weight of sorbitol in sequence, stir evenly, then add 2 parts by weight of sulfuric acid, and keep stirring for at least 2 hours Then it can be used to etch glass. At the same time, if figure 1 As shown, spacers 2 are respectively placed at suitable positions around the plastic hanger 1 for placing the glass 3 to be etched. After the glass is cleaned and back protected, it is placed in the plastic hanger 1 so that the four sides of the glass 3 are placed on the pads. Plate 2, then acid cleaning (the final concentration of acid cleaning solution is 10% hydrofluoric acid and 5% sulfuric acid by mass fraction) pretreatment, then place the second glass 3 in the same way, and finally place the cover plate 4. Place the plastic hanger 1 in the glass etching solution pool 5, hang it out after 2...

Embodiment 2

[0027] Embodiment 2: To prepare an etching solution, first add 60 parts by weight of water into the liquid medicine pool, then add 35 parts by weight of ammonium bifluoride and 8 parts by weight of sorbitol in turn, stir evenly, then add 10 parts by weight of sulfuric acid, and keep stirring for at least 2 hours Can be used to etch glass. At the same time, if figure 1 As shown, spacers 2 are respectively placed at suitable positions around the plastic hanger 1 for placing the glass 3 to be etched. After the glass is cleaned and back protected, it is placed in the plastic hanger 1 so that the four sides of the glass 3 are placed on the pads. On the piece 2, then acid cleaning pretreatment, then place the second piece of glass 3 in the same way, and finally place the cover plate 4. Place the plastic hanger 1 in the glass etching solution pool 5, hang it out after 40 minutes of reaction, and quickly wash off the reactants on the glass surface with water. The particles become la...

Embodiment 3

[0029] Embodiment three: prepare etchant, first add 50 parts by weight of water in the liquid medicine pool, then drop into fluorine successively

[0030] 30 parts by weight of ammonium hydrogen chloride and 5 parts by weight of sorbitol were stirred evenly, and then 5 parts by weight of sulfuric acid was added, and kept stirring for at least 2 hours before being used for etching glass. At the same time, if figure 1 As shown, spacers 2 are respectively placed at suitable positions around the plastic hanger 1 for placing the glass 3 to be etched. After the glass is cleaned and back protected, it is placed in the plastic hanger 1 so that the four sides of the glass 3 are placed on the pads. On the piece 2, then acid cleaning pretreatment, then place the second piece of glass 3 in the same way, and finally place the cover plate 4. Place the plastic hanger 1 in the glass etching solution pool 5, hang it out after 20 minutes of reaction, and quickly wash off the reactants on the g...

Abstract

The invention belongs to the technical field of glass product processing, and in particular relates to a glass etching solution and a preparation method thereof, an etching process using the glass etching solution, and a prepared glass product. A glass etching solution, comprising the following raw materials in parts by weight: 25-35 parts of ammonium bifluoride, 40-60 parts of water, 2-8 parts of sorbitol and 2-10 parts of sulfuric acid. The performance of the glass obtained by using the glass etching solution to treat the glass is good, and no polishing treatment is required. Moreover, the yield rate of the glass products obtained through the glass etching process of the present invention is high, which is convenient for batch production.

Description

technical field [0001] The invention belongs to the technical field of glass product processing, and in particular relates to a glass etching solution and a preparation method thereof, an etching process using the glass etching solution, and a prepared glass product. Background technique [0002] With the continuous promotion and development of the country's urbanization process, and under the influence of increasingly limited land resources, buildings can only ask for space in the sky. There are more and more high-rise and super high-rise buildings. In the new building structure, there will be jobs Several related departments are gathered in a large room with multiple partitions, which is not only conducive to inter-departmental work communication, but also easy to manage and convenient for employees to handle affairs. Such an open intensive office method has become the first choice and trend of government agencies and even large and small companies. In the past, solid wall...
