Embodiment 1
[0014] Use aluminum profile factory industrial sludge, talcum powder and clay as raw materials, without adding TiO 2 Mineralizer, its formula is as follows:
[0015] Aluminum plant industrial sludge: 49%
[0016] Talc: 24%
[0017] Clay: 27%
Embodiment 2
[0019] Use aluminum profile factory industrial sludge, talcum powder and clay as raw materials, add 1.5% TiO 2 Mineralizer, its formula is as follows:
[0020] Aluminum plant industrial sludge: 48%
[0021] Talc: 24%
[0022] Clay: 26.5%
[0023] TiO 2 Mineralizer: 1.5%
Embodiment 3
[0025] Using aluminum plant industrial sludge, talcum powder and clay as raw materials, adding 1.5% TiO 2 Mineralizer, its formula is as follows:
[0026] Aluminum plant industrial sludge: 48%
[0027] Talc: 24%
[0028] Clay: 25%
[0029] TiO 2 Mineralizer: 3%
[0030] The preparation method of the above-mentioned embodiment: mix the raw materials, grind them in a ball mill for 15 hours, dehydrate the grinding materials through pressure filtration, control the water content to 20%, and extrude them into strip-shaped blanks after vacuum refining. After drying at 80°C for 12 hours, the green body is calcined in a high-temperature furnace at 1350°C, kept for 5 hours, and cooled to room temperature naturally. The synthetic material is crushed and ground into two kinds of particle size products, coarse particle size product: 8-22 mesh; fine particle size product: 180-320 mesh. Cordierite content in the synthetic material: the cordierite content of embodiment 1 is 86%, and th...
