Embodiment 1
[0018] 1) Take 50 parts by weight of clay and 50 parts of bauxite for mixing, and after mixing, put them into a mill for crushing and grinding to 100 mesh;
[0019] 2) adding 5 parts by weight of quicklime into a mill for crushing and grinding to 100 mesh;
[0020] 3) Fully stir and mix 50 parts of crushed clay, 50 parts of bauxite and 5 parts of quicklime, then add them to the mill, and add an appropriate amount of water to grind them into slurry;
[0021] 4) Put the mud into a vacuum aging room with a humidity of 70% for 5 days;
[0022] 5) Then add 10 parts by weight of glass fiber filaments and stir evenly;
[0023] 6) Put the mixed mud into the mold, and shape the blank into the required shape under the action of external force through the plastic forming method;
[0024] 7) Apply a uniform layer of glaze on the surface of the blank;
[0025] 8) Send the glazed blank into a kiln at 1200°C for sintering for 20 hours to obtain the finished product.
Embodiment 2
[0027] 1) Take 70 parts by weight of clay and 30 parts of bauxite for mixing, and after mixing, put them into a mill for crushing and grinding to 100 mesh;
[0028] 2) adding 15 parts by weight of quicklime into a mill for crushing and grinding to 100 mesh;
[0029] 3) Mix 70 parts of crushed clay, 30 parts of bauxite and 15 parts of quicklime thoroughly, then add them to the mill, and add an appropriate amount of water to grind them into slurry;
[0030] 4) Put the mud into a vacuum aging room with a humidity of 95% for 6 days;
[0031] 5) Then add 20 parts by weight of glass fiber filaments and stir evenly;
[0032] 6) Put the mixed mud into the mold, and shape the blank into the required shape under the action of external force through the plastic forming method;
[0033] 7) Apply a uniform layer of glaze on the surface of the blank;
[0034] 8) Send the glazed blank into a kiln at 1300°C for sintering for 30 hours to obtain the finished product.
Embodiment 3
[0036] 1) Take 60 parts by weight of clay and 40 parts of bauxite for mixing, and after mixing, put them into a mill for crushing and grinding to 80 mesh;
[0037] 2) adding 10 parts by weight of quicklime into a mill for crushing and grinding to 80 mesh;
[0038] 3) 60 parts of crushed clay, 40 parts of bauxite and 5-15 parts of quicklime are fully stirred and mixed, then added to the mill, and an appropriate amount of water is added to grind into a slurry;
[0039] 4) Put the mud into a vacuum aging room with a humidity of 95% for 5 days;
[0040] 5) Then add 15 parts by weight of glass fiber filaments and stir evenly;
[0041] 6) Put the mixed mud into the mold, and shape the blank into the required shape under the action of external force through the plastic forming method;
[0042] 7) Apply a uniform layer of glaze on the surface of the blank;
[0043] 8) Send the glazed blank into a kiln at 1300°C for sintering for 30 hours to obtain the finished product.
