Embodiment
[0020] Embodiment: Take 20% of diatomite, 20% of elutriation mud, 22% of kaolin, 28% of feldspar, and 10% of dolomite to make ceramic porcelain clay by weight percentage, and then form the ceramic body without glazing. Firing, the firing temperature is 1080°C, and the water absorption rate of the fired ceramic matrix is 20%;
[0021] Place the ceramic carcass in an environment with an air humidity of 55%, and after placing it for 5 hours, hang the ceramic carcass on a charged metal hook and electrify it with a current of 90 mA;
[0022] Use a spray gun to spray the conductively treated powder coating to the charged ceramic carcass, and the powder coating is evenly adsorbed on the surface of the ceramic carcass;
[0023] Hang the ceramic carcass adsorbed with powder coating in the kiln and heat for 30 minutes, the temperature is controlled at 200°C;
[0024] The heated ceramic carcass is taken out of the furnace and cooled naturally to obtain the product of the present inven...
