preparation example Construction
[0032] The invention provides a kind of preparation method of ground glass, and this preparation method comprises the following steps:
[0033] Step 1, preparation of glass base material:
[0034] The raw materials in the glass base material are weighed according to the proportion, and the raw materials are: 40-50% boron glass powder, 8-10% zinc oxide, 2-3% niobium oxide, 5-8% oxide Bismuth, 10-15% of quartz powder, 5-8% of barium carbonate, 10% of zircon and 2-3% of antimony oxide;
[0035] Put the weighed raw materials into the mixer, and mix the materials for 2-3 hours under the condition that the stirring paddle speed of the mixer is 30 rpm;
[0036] In this step, the mixer preferably adopts a double S-shaped mixer.
[0037] Put the mixed raw materials into an industrial crucible furnace, raise the temperature from room temperature to 1000-1050°C at a rate of 5°C / min, and keep it warm for 1-1.5 hours to make molten glass;
[0038] Pour the molten glass into water, put t...
