Embodiment 1
[0061] In terms of weight percentage, desert aeolian sand 50%, limestone 20%, feldspar 10%, soda ash 4%, barium carbonate 5%, spodumene 6%, alumina 2%, sodium nitrate 2%, borax 0.8%, Antimony oxide 0.2%, batching according to the above components and dosage, put the obtained mixture into a high-temperature furnace for heating, the temperature is controlled at 1480°C, and melt after 24 hours to obtain a glass-ceramic liquid. The glass-ceramic liquid flowing out of the high-temperature melting furnace is extruded into thin-faced pellets with a thickness of 0.3 mm by a twin-roller machine, and then ground on a ball mill to form glass-ceramic powder with a particle size of 320 mesh.
[0062] In terms of weight percentage, get 80% of the prepared glass-ceramic powder, graphite 3%, lime 2%, silicon carbide 5%, boric acid 2% and zinc oxide 8%, and mix uniformly to obtain the foamed glass-ceramic mixture. Use an automatic distributing machine to evenly spread and scrape the foamed gla...
Embodiment 2
[0064] In terms of weight percentage, Yellow River silt 50%, limestone 20%, feldspar 10%, soda ash 4%, barium carbonate 5%, spodumene 6%, alumina 2%, sodium nitrate 2%, borax 0.8%, oxide Antimony 0.2%, mix the ingredients according to the above components and dosage, put the obtained mixture into a high-temperature furnace for heating and melting, the temperature is controlled at 1500°C, and melt after 24 hours to obtain glass-ceramics. The glass-ceramic liquid flowing out of the high-temperature melting furnace is extruded into thin-faced pellets with a thickness of 0.5 mm by a twin-roller machine, and then ground into a glass-ceramic powder with a particle size of 250 mesh on a ball mill.
[0065] In terms of weight percentage, take 80% of the prepared glass-ceramic powder, 5% of high-altitude glass powder, 5% of silicon carbide, 5% of boric acid and 5% of zinc oxide, and mix them uniformly to obtain a foamed glass-ceramic mixture. Use an automatic distributing machine to ev...
Embodiment 3
[0067] In terms of weight percentage, iron tailings 60%, limestone 14%, feldspar 10%, soda ash 3%, barium carbonate 4%, spodumene 4%, sodium nitrate 3%, borax 0.8%, antimony oxide 0.2%, according to The above-mentioned components and dosages are mixed together, and the obtained mixture is put into a high-temperature furnace for heating and melting. The temperature is controlled at 1500° C., and after 24 hours, it is melted to obtain glass-ceramic liquid. The glass-ceramic liquid flowing out of the high-temperature melting furnace is extruded into thin-faced pellets with a thickness of 0.2 mm by a double-roller machine, and then ground into a glass-ceramic powder with a particle size of 100 mesh on a ball mill.
[0068] In terms of weight percentage, take 90% of the prepared glass-ceramic powder, 2% of gypsum, 2% of high-altitude glass powder, 3% of boric acid, 2.6% of zinc oxide and 0.4% of manganese dioxide, and mix them evenly to obtain foamed glass-ceramics. material. Use ...
