Embodiment 1
[0035] 52% of feldspar, 12% of quartz, 21% of iron ore tailings, 4% of limestone, 5% of kaolin and 6% of ashes, the weight ratio of the components is: 2 parts K 2 O, 6 copies of AL 2 o 3 , 63 SiO 2 , 4 copies of P 2 o 5 , 4 Na 2 O, 7 Fe 2 o 3 , 10 parts of CaO and 6 parts of MgO, put them into the ball mill for ball milling, add water, and the ball milling time is 8 hours. After uniform mixing and stirring and fully dissolving, the glaze slurry is obtained. The remaining 0.01% is sieved; the above ball-milled glaze slurry is released from the ball mill, stored in the slurry storage tank and stirred; the glaze slurry passes through a 200-mesh sieve, and the fully suspended glaze slurry is coated on the surface of the body with a concentration of 40 Baume degrees , the thickness of the glaze on the surface of the green body is 0.7mm; when the glaze slurry is applied to the surface of the green body, the green body is wiped with water and dried, and the moisture content of...

[0037] 46% feldspar, 22% quartz, 15% iron ore tailings, 5% limestone, 3% kaolin and 9% ashes, the weight ratio of the components is: 3 parts K 2 O, 7 copies of AL 2 o 3 , 58 SiO 2 , 5 copies of P 2 o 5 , 3 Na 2 O, 4 Fe 2 o 3 , 14 parts of CaO and 4 parts of MgO, put them into the ball mill for ball milling, add water, and the ball milling time is 8.5 hours. After uniform mixing and stirring and fully dissolving, the glaze slurry is obtained, and the fineness of the glaze slurry is controlled at a million-hole sieve The remaining 0.008% is sieved; release the above ball-milled glaze slurry from the ball mill, store it in the slurry storage tank and stir; pass the glaze slurry through a 200-mesh sieve, and apply the fully suspended glaze slurry on the surface of the green body with a concentration of 39 degrees Baume , the thickness of the glaze on the surface of the green body is 0.4mm; when the glaze slurry is applied to the surface of the green body, the green body is ...
Embodiment 3
[0039] 59% feldspar, 17% quartz, 17% iron ore tailings, 2% limestone, 2% kaolin and 3% ashes, the weight ratio of the components is: 2 parts K 2 O, 6 copies of AL 2 o 3 , 70 parts of SiO 2 , 3 copies of P 2 o 5 , 2 Na 2 O, 5 Fe 2 o 3 , 6 parts of CaO and 6 parts of MgO, put them into the ball mill for ball milling, add water, and the ball milling time is 9 hours. After uniform mixing and stirring and fully dissolving, the glaze slurry is obtained. The remaining 0.004% is sieved; release the above ball-milled glaze slurry from the ball mill, store it in the slurry storage tank and stir; pass the glaze slurry through a 200-mesh sieve, and apply the fully suspended glaze slurry on the surface of the body with a concentration of 42 degrees Baume , the thickness of the glaze on the surface of the green body is 0.6mm; when the glaze slurry is applied to the surface of the green body, the green body is wiped with water and dried, and the water content of the green body is cont...
