preparation example Construction

[0041] The present invention also provides the preparation method of above-mentioned stained glass, and ferrosilicon ash, NaNO 3 、Na 2 CO 3 , CaCO 3 、Al 2 o 3 Mix with the coloring agent to obtain a mixture, and then burn the mixture at 1250-1350°C to make glass liquid, and cool it to obtain colored glass. The parts by weight of each raw material are: ferrosilicon ash 120-250 parts, NaNO 3 4-10 parts, Na 2 CO 3 60~150 parts, CaCO 3 35-90 parts, Al 2 o 3 20-50 parts, 0.001-5 parts of coloring agent.

[0042] Among the present invention, the effect of each component in the raw material is as follows:

[0043] The melting point of ferrosilicon ash is relatively high. Sodium carbonate and sodium nitrate are added to reduce the melting point of ferrosilicon ash to about 1000 degrees Celsius; however, sodium carbonate will dissolve the glass in water, so an appropriate amount of CaO (CaCO 3 form), making the glass insoluble in water, Al 2 o 3 The introduction improves g...

Embodiment 1

[0050] Take 123.53 grams of ferrosilicon ash, NaNO 3 4.23 g, Na 2 CO 3 61.53 g, CaCO 3 38.50 g, Al 2 o 3 21.28 g and Fe 2 o 3 1.25 grams of powder, the particle size of these six kinds of powders is 0.061 ~ 0.074mm, mix these six kinds of powders evenly, put the mixture into the crucible, then put the crucible in the muffle furnace, and use 130 minutes to heat up to 1340°C, keep warm for 60 minutes, then cool down to 900°C in 180 minutes and then cool down to room temperature naturally; obtain yellow-green stained glass.

Embodiment 2

[0052] Take 148.23 grams of ferrosilicon ash, NaNO 3 5.07 g, Na 2 CO 3 73.83 g, CaCO 3 45.84 g, Al 2 o 3 25.53 grams and 1.50 grams of Cu powder, the particle size of these six kinds of powders is 0.061 ~ 0.074mm, mix these six kinds of materials evenly, put the mixture into the crucible, then put the crucible in the muffle furnace, use 133 The temperature was raised to 1345°C within 1 minute, and the temperature was kept for 63 minutes, then the temperature was lowered to 942°C in 186 minutes, and then the room temperature was cooled naturally; light yellow stained glass was obtained.

Abstract

The invention relates to a manufacturing method of colored glass, in particular to a method for manufacturing the colored glass through silicon iron ash, and belongs to the field of inorganic materials. The colored glass is composed of, by weight, 118-280 parts of SiO2, 37-97 parts of Na2O, 19-51 parts of CaO, 20-50 parts of Al2O3 and 0.001-5 parts of coloring agents. The colored glass is manufactured with the silicon iron ash as the raw materials, the process is simple, cost is low, the colored glass is environmentally friendly, and continuous and industrial production is achieved easily. The colored glass obtained according to the method is rich in color.

Description

technical field [0001] The invention relates to colored glass and a preparation method thereof, belonging to the field of inorganic non-metallic materials. Background technique [0002] Ferrosilicon ash is a kind of industrial waste slag formed in the smelting of ferrosilicon alloy, and the smoke and dust escaping with the exhaust gas is collected and processed by a special collection device. Ferrosilicon dust contains a large amount of amorphous silicon oxide, such as SiO 2 Calculated, its content can reach more than 90%. At present, the use of ferrosilicon ash is mainly used as an additive for cement and refractory materials, a binder for metallurgical pellets, a dispersant for chemical products, a filler for rubber and plastics, a plastic sealant for the electronics industry, and a pouring for the electrical industry. There are many ferrosilicon production enterprises in my country, and a large amount of ferrosilicon ash is produced every year, and the current method of...
