Embodiment 1
[0028] Superplastic clay dry powder 25%, white mud dry powder 35%, feldspar powder 20%, 8-20 mesh coarse aggregate 20%; barium carbonate 0.5%, high-temperature pigment 3.0%, dry mix the above raw materials in a mixer for 30 minutes. Afterwards, it will be stale in the stale room for 2-3 days; then add 16% water to the stale material and mix it in a planetary mixer for 20 minutes; install a back-hanging extrusion die with a width of 300 mm and a thickness of 18 mm, at both ends of the die mouth at 3-4 mm Fix the fine steel wire so that it can be stretched straight when extruding; add material for vacuum extrusion, remove and recycle the wet material on the surface of the steel wire; dry the wet billet in a multi-layer drying kiln for 4 hours at a temperature of 160-180 °C; After drying, it is fired in a roller kiln at 1160°C for 4 hours; after sorting, cutting, and packaging, 18mm thick back-hanging brushed finish exterior wall dry-hanging ceramic panels are produced.
Embodiment 2
[0030] With reference to the method of Example 1, superplastic clay dry powder 35%, white clay dry powder 30%, feldspar powder 15%, 8-20 purpose coarse aggregate 20%; barium carbonate 0.5%, high-temperature colorant 4.0%, the above-mentioned raw materials are mixed in the blender Dry mix for 30 minutes. Afterwards, it will be stale in the stale room for 2-3 days; then add 16% water to the stale material and mix it in a planetary mixer for 20 minutes; install a side-hanging extrusion mold with a width of 600 mm and a thickness of 30 mm, and place the two ends at the die mouth at 3-4 mm Fix the thin steel wire so that it can be stretched straight when extruding; vacuum extrusion is added to remove and recycle the wet material on the surface of the steel wire; the wet billet is dried in a multi-layer drying kiln for 6 hours at a temperature of 160-180 °C; After drying, it is fired in a roller kiln at 1160°C for 6 hours; after sorting, cutting, and packaging, a 30 mm thick side-ha...
