Embodiment 1
[0029] A method for applying a kaolin porcelain body. According to the mass percentage of the body, 30 wt% of raw kaolin, 57 wt% of calcined kaolin at 850°C, 2.5 wt% of potassium feldspar, 7.5 wt% of tremolite, and 3 wt% of frit %, plus 0.05 wt% fairy water, ball milled after mixing, the ball milling medium is Al 2 o 3 Grinding balls, the ratio of material to water is 1: 2: 0.6, and the ball milling time is 30 minutes. The slurry after ball milling is passed through a 250-mesh sieve, and the sieve residue is less than 0.1%, and then dried in an oven at 80°C for a period of time. The powder obtained after drying is granulated, aged for a period of time, and then pressed into long strips (60 mm in length) with a pressure of 10 MPa; the pressed long strips are dried to constant weight and then fired in an electric furnace. Firing at 1310°C, holding time for 30 min, and then cooling with the furnace; the water absorption rate of the obtained porcelain body is 0.16%, and the bulk ...
Embodiment 2
[0031] A method for applying a kaolin porcelain body. According to the mass percentage of the body, 25 wt% of raw kaolin, 65 wt% of calcined kaolin at 1150°C, 3.4 wt% of potassium feldspar, and 3.3 wt% of tremolite are firstly melted. The block is 3.3 wt%, plus 0.05 wt% fairy water, and ball milling is carried out after mixing, and the ball milling medium is Al 2 o 3 Grinding balls, the ratio of material to water is 1:2:0.6, and the ball milling time is 30 minutes. The slurry after ball milling is passed through a 250-mesh sieve, and the sieve residue is less than 0.1%, and then dried in an oven at 80 °C for a period of time. The powder obtained after drying is granulated, stale for a period of time, and pressed into long strips (60 mm in length) with a pressure of 10 MPa. The pressed strips were dried to constant weight and fired in an electric furnace at 1370°C for 30 minutes, then cooled in the furnace; the water absorption rate of the obtained porcelain body was 0.48%, an...
Embodiment 3
[0033] A method for applying a kaolin porcelain body. According to the mass percentage of the body, 25 wt% of raw kaolin, 60 wt% of calcined kaolin at 1050°C, 6 wt% of potassium feldspar, and 4 wt% of tremolite are firstly melted. The block is 5 wt%, plus 0.05wt% fairy water, and ball milling is carried out after mixing, and the ball milling medium is Al 2 o 3 Grinding balls, the ratio of material to water is 1:2:0.6, and the ball milling time is 30 minutes. The slurry after ball milling is passed through a 250-mesh sieve, and the sieve residue is less than 0.1%, and then dried in an oven at 80 °C for a period of time. The powder obtained after drying is granulated, stale for a period of time, and pressed into long strips (length specification is 60 mm), and the pressure is controlled at 10MPa. The pressed strips were dried to constant weight and then fired in an electric furnace at 1340°C for 30 min, then cooled with the furnace; the water absorption rate of the obtained por...
