Problems solved by technology

However, in this color development technology, after the color development treatment, it is difficult to keep the cooling rate of each part of the glass (such as different regions of the product) consistent during the cooling process of the glass product, resulting in poor color uniformity of the product; another On the one hand, the production efficiency is not high, and it is not suitable for industrial scale production

Embodiment 1

[0033] 1) The composition ratio (wt%) is SiO 2 : 68%; Al 2 o 3 : 3%; B 2 o 3 : 10%; Na 2 O: 5%; K 2 O: 4%; ZnO: 10%; CdS: 1.2%; Se: 0.5%. Mix evenly, place in a corundum crucible, melt at 1400-1550°C, press at 1300°C to form several glass lamps with a weight of 100 grams, the size is Φ80×50mm, and the wall thickness is 3mm. Grind the bayonet of the annealed glass lamps for color enhancement treatment.

[0034] 2) Using 100wt% KNO 3 As a molten salt, it is melted in an electric furnace and clarified for more than 24 hours for later use.

[0035] 3) Put the glass lamp made in step 1) into the heat-resistant tooling, hang the tooling in an electric furnace at a temperature of 660°C for color development, and the color development time is 20 minutes. Then, remove the tooling from the electric furnace and quickly put it into 100wt% KNO 3 In the molten salt, the temperature of the molten salt is 380° C., and the time is 5 minutes.

[0036] 4) Take out the glass lamp from ...

Embodiment 2

[0045] The same steps as in Example 1 were adopted. The difference is that in step 3), the glass lamps are put into the heat-resistant tooling, and the color development process is carried out in an electric furnace at a temperature of 670° C., and the color development time is 20 minutes.

[0046] The product of Example 2 is detected according to the detection method of the embodiment, and the data are listed in Table 2.

Embodiment 3

[0048] The same steps as in Example 1 were adopted. The difference is that in step 3), the glass lamps are put into the heat-resistant tooling to carry out the color development treatment in an electric furnace at a temperature of 680° C., and the color development time is 20 minutes.

[0049] The product of Example 3 is detected according to the detection method of the embodiment, and the data are listed in Table 2.

Abstract

The invention relates to a color development enhancing method for glass, belongs to the technical field of glass processing and is mainly used for signal glass or filter glass. The method comprises the following steps: preparing a glass product according to the glass composition, performing color development treatment, then quickly putting the glass product into a liquid cooling medium to be cooled, taking the glass product out to be cooled naturally, and cleaning and drying the glass lamp. The liquid medium is oil of which the relative viscosity is 30 to 100 Pa.s and the flashing point is 220 to 310 DEG C, and the oil comprises mineral oil, molten potassium nitrate, molten sodium nitrate and silicone oil. The colored glass after the color development enhancing treatment becomes heat-resistant glass so as to not only improve the coloring evenness, glass strength and thermal stability, but also enlarge the application ranges of the signal glass and the filter glass. The color development enhancing method for the glass has the characteristics of simple operation, low cost, high finished product rate and good repeatability, and is suitable for industrialized mass production.

Description

technical field [0001] The invention belongs to the technical field of glass processing, and in particular relates to a color enhancement technology for signal glass or filter glass, so as to improve the uniformity of glass coloring, glass strength and thermal stability. Background technique [0002] The glass colored with cadmium selenium sulfide has special spectral characteristics, first of all, the color is pure, bright, high transmittance, and the light absorption curve is steep (absorption and transmission boundaries are clear). It can make the transmittance almost from zero to the maximum in a very narrow wavelength band, which is very rare in the light absorption curve of colored glass. Another feature is that the color change of this type of glass is continuous. The color of the glass changes from yellow to orange, red and deep red, and the light absorption curve moves to the long wave, and a series of colors from 520 to 760nm wavelength can be obtained. Finally, ...
