Embodiment 1

[0020] Embodiment 1: the preparation method of a kind of glass with holes of the present invention specifically has the following steps:

[0021] S1. Select a glass substrate and melt the glass substrate to obtain a glass melt.

[0022] S2. Arrange a tin bath for containing tin liquid, heat the temperature of the tin liquid in the tin bath to 450°C, add additives to the tin bath, the additive is iron-tin monotectic alloy or iron-tin sub-motetectic alloy, wherein tin The mass percentage content is 38%; the tin bath is made of limestone, dolomite, magnesite, soda ash, silicon carbide, graphite, sodium sulfate, magnesium sulfate dolomite, perlite, hematite or pyrolusite. The tin bath is a sealed structure, which ensures that the forming and hole-forming process of the glass with holes is carried out under sealed conditions. There is an inert gas in the tin bath, and the inert gas is nitrogen.

[0023] S3. Add the molten glass to the tin bath, and the molten glass floats on the s...

Abstract

The invention relates to the technical field of reshaping of glass plates and specifically discloses a method for preparing glass with holes. The method comprises the following steps: S1, selecting a glass substrate, and smelting the glass substrate so as to obtain glass melted liquid; S2, arranging a molten tin bath for containing tin liquor; S3, adding the glass melted liquid into the molten tin bath, and enabling the glass melted liquid to float on the surface of an additive; S4, adding a hollow aluminum ball into the molten tin bath, wherein the hollow aluminum ball floats on the additive and is positioned in the glass solution; S5, cooling the glass to form a glass plate, wherein the hollow aluminum ball is inlaid on the glass plate; S6, cleaning the glass plate with the hollow aluminum ball in a dilute nitric acid solution; and S7, annealing the glass plate, performing cutting and polishing treatment, thereby obtaining the glass with holes. Compared with the existing glass drilling processing, the method in the technical scheme has the advantages that glass material removal processing is avoided, the glass materials are saved, the problem that the glass is easy to break in the drilling process is solved, and the processing yield of the glass with holes is improved.

Description

technical field [0001] The invention relates to the technical field of reshaping of glass plates. Background technique [0002] In recent years, glass has increasingly become an indispensable decoration in the home, such as materials for doors and windows, dining table panels, etc. In order to increase the practicability and beauty of the glass, it is usually necessary to process several through holes on the glass. The through holes are evenly covered on the glass plate, which can leak the water quality on the plate surface, reduce the weight of the glass, and also have a certain anti-skid effect. , Perforated glass is more suitable for processing raw materials for some decorative panels. Most of the existing glass with holes is processed by drilling, but the processing of glass with holes by drilling has the following defects: the glass surface is easily damaged due to stress during drilling, resulting in the scrapping of the whole glass, especially It is for thinner glas...
