Problems solved by technology

Tempered glazed glass is a new type of decoration with high acid and alkali resistance and high safety obtained by printing glass glaze on the glass surface through screen printing, drying and tempering, and permanently sintering the glaze on the glass surface. Glass products, in which the content of harmful organic substances and radioactive elements are basically free; the size can be customized on the market at present, but this kind of glass has the disadvantages that it cannot be subjected to secondary processing such as punching and cutting, and the shape cannot be changed, which makes the decoration The autonomy of the

Embodiment 1

[0015] Colored glazed glass, the specific preparation steps are as follows:

[0016] 1) First clean the transparent flat glass and dry it at 100°C;

[0017] 2) The cleaned glass is passed through a roller coating machine, and a layer of white high-temperature inorganic water-based glass ink is rolled, and the number of lines of the roller used is 55 lines, and the ink consumption is 160 grams per square meter;

[0018] 3) Heat and dry the glass with white inorganic ink at 150°C;

[0019] 4) Transfer the above glass to a heating furnace for heating at a temperature of 680°C;

[0020] 5) Anneal the glass above the softening point temperature. In the first stage, the set temperature of the annealing furnace is 381°C in the upper part and 406°C in the lower part, so that the glass surface temperature drops to 580°C; the set temperature in the upper part of the second stage is 394°C, the lower set temperature is 448°C, and the glass surface temperature drops to 550°C; the third s...

Embodiment 2

[0022] Colored glazed glass, the specific preparation steps are as follows:

[0023] 1) First clean the transparent flat glass and dry it at 120°C;

[0024] 2) Put the pre-designed screen on the cleaned glass, use red high-temperature inorganic water-based ink to print on the designed screen, and the ink consumption is 50 grams per square meter;

[0025] 3) Heat and dry the glass with red inorganic water-based ink at 140°C;

[0026] 4) Transfer the above-mentioned glass to a heating furnace for heating at a temperature of 670°C;

[0027] 5) Anneal the glass with a temperature above the softening point. The temperature of the annealing furnace in the first stage is set at 390°C for the upper part and 400°C for the lower part; for the second stage, the set temperature for the upper part is 395°C and the set temperature for the lower part is 430°C The upper part of the third stage is 249°C, and the lower part is 260°C; the fourth stage is 100°C, the fifth stage is natural cooli...

Embodiment 3

[0029] Colored glazed glass, the specific preparation steps are as follows:

[0030] 1) First clean the transparent flat glass and dry it at 150°C;

[0031] 2) The cleaned glass is passed through a roller coating machine, and a layer of green high-temperature inorganic water-based glass ink is rolled, and the number of lines of the roller used is 55 lines, and the ink consumption is 150 grams per square meter;

[0032] 3) Heat and dry the glass with green inorganic water-based ink at 150°C;

[0033] 4) Transfer the above glass to a heating furnace for heating at a temperature of 685°C;

[0034] 5) Anneal the glass with a temperature above the softening point. The set temperature of the annealing furnace in the first stage is 381°C in the upper part and 406°C in the lower part; in the second stage, the set temperature in the upper part is 394°C and the set temperature in the lower part is 448°C ; The upper part of the third stage is 259°C, the lower part is 288°C; the fourth ...

Abstract

The invention belongs to the technical field of deep processing of glass, in particular to colored glazed glass and a production method thereof. The colored glazed glass is prepared by the following method: cleaning a glass substrate, then drying, roll-coating a layer of high-temperature inorganic glass glaze or screen-printing the glass glaze on the surface of the glass, and they drying; and further heating the glass to a softening point, and then slowly reducing the temperature for annealing, thereby preparing a finished product. The color glazed glass produced by the method does not contain volatile harmful substances and can be any color and translucent or opaque; and the secondary processing can be carried out, and the glass has no deformation or color change, thereby being an environment-friendly high-grade glass decorative product which can meet the needs of customers to the maximum extent; in addition, the glass substrate can be any dimension, and the maximum dimension of the glass which can be produced is 1.83 multiplied by 2.44M.

Description

(1) Technical field [0001] The invention belongs to the technical field of glass deep processing, and in particular relates to colored glaze glass and a production method thereof. (2) Background technology [0002] With the rapid development of today's society, people's quality of life has been greatly improved, and the requirements for quality and environmental protection of indoor and outdoor decoration materials are becoming more and more stringent. However, most of the decoration materials currently on the market have different defects, such as: ordinary painted glass back The paint is easy to fall off, easy to change color and fade. Because the low-temperature organic ink is used in the production process, it is easy to volatilize harmful substances such as benzene and toluene, which is harmful to human health. Most of the decoration materials such as marble and granite have certain radioactivity, and there are many examples at home and abroad that the health of people ...
