Embodiment 1

[0056] The ingredients of jade-colored high borosilicate 3.3 glass are: 8000kg of silicon dioxide, 1200kg of boron, 220kg of alumina, 420kg of sodium chloride, 80kg of calcium carbonate, 20kg of ammonium dihydrogen phosphate, and 20kg of aluminum dihydrogen phosphate, mix well and set aside. The 24-hour feeding capacity is 4800 kg.

[0057] The product preparation process and flow chart are shown in image 3 :

[0058] (1) Cold top stage: the temperature in the cold top layer of the kiln is maintained at 500°C for 8 hours, the current input to the kiln is about 300A, and ingredients are added every 5-10 minutes to make the top layer of the kiln always have The ingredients of 30-50 cm are in a solid state, forming an insulating layer. The ingredients will flow to the heating layer under the kiln continuously over time, and other ingredients and colorants that start to melt in the heating layer will gradually fuse to ensure coloring The agent is not volatile;

[0059] (2) Hea...

Embodiment 2

[0065] The composition ratio of jade color high borosilicate 3.3 glass rod is: 8060kg of silicon dioxide, 1260kg of boron, 240kg of alumina, 460kg of sodium chloride, 90kg of calcium carbonate, 40kg of ammonium dihydrogen phosphate, 30kg of aluminum dihydrogen phosphate, mix well and set aside. The 24-hour feeding capacity is 6000 kg.

[0066] The product preparation process is:

[0067] (1) Cold top stage: The temperature in the cold top layer of the kiln is maintained at 500°C for 8 hours, the current input to the kiln is about 500A, and ingredients are added every 5-10 minutes so that the top layer of the kiln is always energized. The ingredients of 30-50 cm are in a solid state, forming an insulating layer. The ingredients will flow to the heating layer under the kiln continuously over time, and other ingredients and colorants that start to melt in the heating layer will gradually fuse to ensure coloring The agent is not volatile;

[0068] (2) Heating stage: the temperat...

Embodiment 3

[0074] The ingredients of jade-colored high borosilicate 3.3 glass are: 7500kg of silicon dioxide, 1000kg of boron, 100kg of alumina, 300kg of sodium chloride, 50kg of calcium carbonate, 10kg of ammonium dihydrogen phosphate, and 10kg of aluminum dihydrogen phosphate. The 24-hour feeding capacity is 6000 kg. The product preparation process is:

[0075] (1) Cold top stage: the temperature in the cold top layer of the kiln is kept at 490°C for 8 hours, the current input to the kiln is about 400A, and ingredients are added every 5-10 minutes to make the top layer of the kiln always have The ingredients of 30-50 cm are in a solid state, forming an insulating layer. The ingredients will flow to the heating layer under the kiln continuously over time, and other ingredients and colorants that start to melt in the heating layer will gradually fuse to ensure coloring The agent is not volatile;

Abstract

The invention discloses white jade color high borosilicate glass and a preparation method thereof. On the basis of maintaining original properties of high borosilicate 3.3 glass, the glass is internally colored, and by selecting a coloring agent in a formula of the high borosilicate 3.3 glass, selecting the ratio of the coloring agent to other materials, and strictly controlling the melting temperature and the melting time, so that the effect that a coloring agent is not volatilized is achieved, the prepared glass is of a white jade color, is uniformly distributed and is free of bubble or water wave, and is excellent in refractive index or light transmittance.

Description

technical field [0001] The invention relates to the field of glass, in particular to a white jade-colored high borosilicate 3.3 glass and a preparation method thereof Background technique [0002] At present, there are ordinary stained glass and high borosilicate glass on the market. High borosilicate 3.3 glass has color pattern perboric acid 3.3 glass, red high borosilicate glass, but there are few perboric acid 3.3 glass like white jade. Hetian jade is famous all over the world because of its extremely fine grain size, warm and moist appearance, moderate transparency and high hardness. All kinds of pendants, decorations and utensils made of it are elegant in appearance and expensive. Because of the high hardness and high price of real jade, Therefore, it cannot be used when making handicrafts with complex shapes and large volumes. In the case that Hetian white jade materials cannot meet the production process, in order to meet market demand, a glass product with a high de...
