Problems solved by technology

[0002] In the production process of optical glass products, glass slag produced by cutting and other intermediate products such as optical glass substrates and display panels will cause slight scratches on the glass surface. If such defects cannot be eliminated in time and directly enter the next production process, it will cause As a result, the yield rate of optical products has dropped significantly. The product repair paste of this project is applied to the production process of optical products to eliminate slight scratches in the production process of each process and achieve the purpose of improving the yield rate of optical products; Some optical glass scratche

Embodiment 1

[0029] 1. According to the ratio of 2.5 parts of water, 2 parts of ammonium bifluoride, 0.5 parts of hydrofluoric acid, 1 part of nitric acid, 0.5 parts of phosphoric acid, 1 part of oxalic acid, 2 parts of calcium dihydrogen phosphate, and 0.05 parts of gum, prepare glass slight scratch repair paste;

[0030] 2. Fully stir the prepared scratch repair paste in the PVC container;

[0031] 3. Then pack it into PVC plastic barrels and keep it sealed;

[0032] 4. It can be put into use after being stirred evenly again during use; the repair effect of slight scratches on the glass after use is very good.

Embodiment 2

[0034] 1. According to the ratio of 3 parts of water, 2.5 parts of ammonium bifluoride, 0.5 parts of hydrofluoric acid, 0.5 parts of nitric acid, 0.5 parts of phosphoric acid, 1 part of oxalic acid, 2.5 parts of calcium dihydrogen phosphate, and 0.05 parts of gum, prepare glass slight scratch repair paste;

[0035] 2. Fully stir the prepared scratch repair paste in the PVC container;

[0036] 3. Then pack it into PVC plastic barrels and keep it sealed;

[0037] 4. During the service period, it should be stirred evenly before it can be put into use; after use, the repair effect of slight scratches on the glass is very good.

Embodiment 3

[0039] 1. According to the ratio of 2 parts of water, 2 parts of ammonium bifluoride, 0.5 parts of hydrofluoric acid, 1.5 parts of nitric acid, 0.5 parts of phosphoric acid, 1 part of oxalic acid, 2.5 parts of calcium dihydrogen phosphate, and 0.05 parts of gum, prepare glass slight scratch repair paste;

[0040] 2. Fully stir the prepared scratch repair paste in the PVC container;

[0041] 3. Then pack it into PVC plastic barrels and keep it sealed;

[0042] 4. During the service period, it should be stirred evenly before it can be put into use; after use, the repair effect of slight scratches on the glass is very good.

Abstract

The invention relates to the field of optical glass repair, and particularly relates to repairing paste for slight scratches of optical glass. The repairing paste is prepared from the following components in parts by weight: 1.5 to 2.5 parts of ammonium bifluoride, 2 to 3 parts of water, 0.2 to 0.5 part of hydrofluoric acid, 0.5 to 1.5 parts of nitric acid, 0.5 to 1 part of phosphoric acid, 1 to 5parts of oxalic acid, 1.5 to 2.5 parts of monocalcium phosphate and 0.05 to 0.2 part of Arabic gum. The repairing paste provided by the invention can be widely applied to each production process of optical products, eliminates slight scratches in the production process of each process, and achieves the purpose of improving the yield of the optical products; the repairing paste product can realizerepairing work of slight scratches of the optical glass, has the advantages of simple process method, high repairing efficiency, low repairing cost and the like, and improves the product yield of theoptical glass in the production process.

Description

technical field [0001] The invention belongs to the field of optical glass repair, and in particular relates to a repair paste for slight scratches on optical glass. Background technique [0002] In the production process of optical glass products, the glass slag produced by cutting and other intermediate products such as optical glass substrates and display panels will cause slight scratches on the glass surface. If such defects cannot be eliminated in time and directly enter the next production process, it will cause As a result, the yield rate of optical products has dropped significantly. The product repair paste of this project is applied to the production process of optical products to eliminate slight scratches in the production process of each process and achieve the purpose of improving the yield rate of optical products; Some optical glass scratches are generally repaired by grinding and polishing physical processes. This grinding and polishing process will cause l...
