Problems solved by technology

[0003] At present, there are also chemical tempering methods for glass tempering. The strength of chemical tempered glass is close to that of physical tempered glass, but the time is too long, the efficiency is low and the production cost is high.
[0004] Not only that, but at present, tempered glass has the problem of poor pollution resistance during use, especially in northern regions where there is a lot of dust in the atmosphere, serious air pollution, drought and little rain, tempered glass is very easy to be dusty, uneven in color, affecting beautiful
The cleaning technology of tempered glass is demanding and difficult, and it is easy to pollute the surrounding environment after cleaning with a large amount of organic solvents and acidic detergents, and the discharge of cleaning waste is also a problem

Embodiment 1

[0031] A method for making tempered glass with a surface coating, comprising the following steps:

[0032] (1) Put the glass on the roller table, send it into the tempering furnace through the roller table and let it stand at 600°C-610°C for 10-15min, then reduce the temperature in the furnace evenly and slowly to 180-200°C within 40min, and put the glass again Stand in the furnace for 5-8min;

[0033] (2) Take the glass out of the furnace and apply a layer of paint, the paint is made of the following raw materials,

[0034] 4-8 parts of metasilicate, 5-10 parts of nano cobalt oxide,

[0035] 3-7 parts of lithium oxide, 4-10 parts of nano molybdenum trioxide,

Abstract

The invention discloses a production method of tempered glass with a surface coating. The production method comprises the steps as follows: (1) placing glass on a roller table, sending the glass intoa tempering furnace through the roller table, leaving the glass to stand at 600-610 DEG C for 10-15 min, then, uniformly and slowly decreasing the temperature in the furnace to 180-200 DEG C within 40min, and leaving the glass to stand in the furnace for 5-8 min; (2) after taking the glass out of the furnace, and coating the glass with a coating prepared from raw materials as follows: 4-8 parts of metasilicic acid, 5-10 parts of nano cobalt oxide, 3-7 parts of lithium oxide, 4-10 parts of nano molybdenum trioxide, 3-9 parts of disilicic acid, 70-85 parts of ethyl alcohol, 6-12 parts of sepiolite powder and 3-6 parts of calcium oxide. The tempered glass has the characteristics of high production yield, high strength and good self-cleaning effect.

Description

technical field [0001] The invention relates to the field of glass processing, in particular to a method for making tempered glass with a surface coating. Background technique [0002] Tempered glass has been widely used due to its advantages such as high mechanical strength, excellent thermal shock resistance, and good safety. Most of the existing tempered glass production processes adopt the tempering process using air as the cooling medium, so that the heated glass is subjected to chilling treatment in a short period of time through a large amount of air, thereby completing the tempering process. In order to ensure the performance of tempered glass, it is usually necessary to provide a large flow of air in a short period of time, especially when tempering thin glass. Usually, a high-power fan with high wind pressure and large flow is used to blow air at the same time. [0003] At present, there are also chemical tempering methods for glass tempering. The strength of chem...
