Example Embodiment
[0015] Example 1:
[0016] 1) First, peel off the glass in the discarded liquid crystal display from the display, crush it and grind it through a 20-mesh sieve for use; then, dry the kaolin and grind it to 20 mesh for use;
[0017] 2) Take 30% of the broken ball milled waste glass and 70% of kaolin according to the mass fraction and mix them into a ball mill tank, then add 2% of the mixture mass of distilled water, ball mill and mix uniformly to form a batch;
[0018] 3) Put the batch material into a 50mm(L)x40mm(W)x8mm(H) grinding tool, dry-press it into a ceramic tile body under a pressure of 5MPa, and then place the formed ceramic tile body at room temperature for 24h Then put it in an oven and bake at 110°C for 24 hours, then put the baked sample in the furnace, and sinter according to the following process:
[0019] In the preheating stage, the temperature rises from room temperature to 110°C at a heating rate of 3°C / min;
[0020] In the heating stage, the temperature is increased...

[0031] Example 3:
[0032] 1) First, peel off the glass in the discarded liquid crystal display from the display, crush it and grind it through a 20-mesh sieve for use; then, dry the kaolin and grind it to 20 mesh for use;
[0033] 2) Take 40% of the broken ball-milled waste glass and 60% of kaolin according to the mass fraction and mix them into the ball mill tank, then add 0.5% distilled water of the mixture mass, and form a batch after the ball mill is evenly mixed;
[0034] 3) Put the batch material into a 50mm(L)x40mm(W)x8mm(H) grinding tool, dry-press it into a ceramic tile body under a pressure of 5MPa, and then place the formed ceramic tile body at room temperature for 24h Then put it in the oven and bake at 150℃ for 24h, then put the baked sample in the furnace, and sinter according to the following process:
[0035] In the preheating stage, the temperature rises from room temperature to 120°C at a heating rate of 4°C / min;
[0036] In the heating stage, the temperature is incr...
