Embodiment 1
[0049] Step 1: The green body formula is: by mass, selected sodium stone powder 8.5%, terrazzo powder 11%, high-strength washed mud 12%, black talc 1.5%, high white alumina 6%, potassium feldspar powder 25%, washed ball Soil 12%, potassium aluminum sand 15%, albite powder 9%. The chemical composition of the formula is: by mass, SiO 2 : 64%, Al 2 o 3 : 23%, Fe 2 o 3 : 0.4%, TiO 2 : 0.3%, CaO: 0.3%, MgO: 0.5%, K 2 O: 3%, Na 2 O: 3.5%, loss on ignition 5%. Batch according to the green body formula, ball mill, and carry out slurry color matching according to the design pattern. Adjust the color and design pattern by adjusting the amount of colorant added.
[0050] Step 2: Use a large-tonnage press HT36000 to form a green body with a size of 1600×3600×15.5mm; dry the green body for 80 minutes at a drying temperature of 120°C.
[0051] Step 3: Use a digital printer to spray white ink and ink of other colors to form a pattern layer decoration.
[0052] Step 4: Use a swing-t...
Embodiment 2
[0060] The difference from Example 1 is that the green body formula is: by mass, selected sodium stone powder 9%, terrazzo powder 11%, high-strength washed mud 13%, black talc 2%, high white alumina 6%, potassium long Stone powder 25%, washed ball soil 12%, potassium aluminum sand 14%, albite powder 9%. The chemical composition of the formula is: by mass, SiO 2 : 65%, Al 2 o 3 : 22.5%, Fe 2 o 3 : 0.4%, TiO 2 : 0.3%, CaO: 0.3%, MgO: 0.5%, K 2 O: 3.5%, Na 2 O: 3%, loss on ignition 4.5%. According to the test, the antifouling grade of the obtained slate is 5 grades, the wear resistance reaches 6000 rpm (4 grades), the antibacterial rate of Escherichia coli is 95.38%, and the antibacterial rate of Staphylococcus aureus is 98.52%.
Embodiment 3
[0062] The difference from Example 1 is that the formula of the antibacterial glaze powder is: by mass, potassium albite feldspar 43%, kaolin 8%, calcined kaolin 5%, dolomite 10%, wollastonite 8%, zinc oxide 5% %, barium carbonate 8%, calcined talc 9%, zirconium phosphate silver-loaded antibacterial agent 2.0%, bismuth oxide 1.5%, cerium oxide 0.5%. The chemical composition of the antibacterial glaze powder includes: by mass, SiO 2 : 47.8%, Al2 o 3 : 18.8%, CaO: 8.4%, K 2 O: 3.12%, ZnO: 5.5%, Na 2 O: 2.2%, MgO: 0.4%, BaO: 6.1%, Bi 2 o 3 : 1.6%, CeO 2 : 0.2%, P 2 o 5 : 1.2%, ZrO 2 : 1.0%, Ag: 0.18%, loss on ignition: 3.6%.
[0063] The test shows that the antibacterial rate of Escherichia coli is 93.56%, and the antibacterial rate of Staphylococcus aureus is 92.74%.
