Example Embodiment
[0031] Example 1:
[0032] 1. Ingredients:
[0033] The proportion of raw materials is calculated in the following weight percentages: phosphogypsum 19.5%, red mud 13%, feldspar 7%, kaolin 17.5%, dispersant (sodium hexametaphosphate) 0.5%, quartz 8%, water 34.5%.
[0034] 2. Mixing: Mix the ingredients into a slurry to make the fluidity reach 35 seconds, which meets the requirements of the national standard QB / T 1545-1992.
[0035] 3. Mud treatment: spray-dry the mixed mud.
[0036] 4. Forming: Press and form the dried material to obtain the green body of ceramic floor tiles.
[0037] 5. Sintering: The green body is sintered at 1200°C for 60 minutes to obtain ceramic floor tiles.
[0038] After testing, the water absorption rate of ceramic floor tiles is 7.5%, and the compressive strength is 650N, which all meet the requirements of the national standard GB / T 4100-2006.
Example Embodiment
[0039] Example 2:
[0040] 1. Ingredients:
[0041] The raw material ratio is based on the following weight percentages: phosphogypsum 19.5%, red mud 13%, feldspar 7%, kaolin 17.5%, dispersant sodium tripolyphosphate 0.75%, quartz 8%, water 34.5%.
[0042] 2. Mixing: Mix the ingredients into a slurry to make the fluidity reach 38 seconds, which meets the requirements of the national standard QB / T 1545-1992.
[0043] 3. The other steps are the same as in Example 1.
[0044] After testing, the water absorption rate of ceramic floor tiles is 8%, and the compressive strength is 640N, which all meet the requirements of the national standard GB / T 4100-2006.
Example Embodiment
[0045] Example 3:
[0046] 1. Ingredients:
[0047] The raw material ratio is based on the following weight percentages: phosphogypsum 19.5%, red mud 13%, feldspar 7%, kaolin 17.5%, dispersant sodium silicate 1%, quartz 8%, water 34%.
[0048] 2. Mixing: Mix the ingredients into a slurry to make the fluidity reach 37 seconds, which meets the requirements of the national standard QB / T 1545-1992.
[0049] 3. The other steps are the same as in Example 1.
[0050] After testing, ceramic floor tiles have a water absorption rate of 9% and a compressive strength of 630N, which all meet the requirements of the national standard GB / T 4100-2006.
