Embodiment 1
[0043] A forsterite-based foam ceramic for carbon sequestration and a preparation method thereof, comprising the following steps:
[0044] S1, 100 parts of forsterite powder, 2 parts of kaolin powder, 3 parts of potassium feldspar powder, 4 parts of potassium oxide powder and 6 parts of boron oxide powder are uniformly mixed for 0.5h to obtain the main ingredient, while the carboxymethyl 8wt% of the main ingredient is mixed Cellulose, 2wt% sodium dodecylbenzene sulfonate and 70wt% deionized water are mixed into an additive solution; the additive solution is poured into the main material and mixed for 2 hours to obtain a ceramic slurry;
[0045] S2. Immerse the polyurethane foam template into the ceramic slurry in step S1, take out and squeeze the excess slurry; and then dry the template at 65°C for 8 hours to obtain a ceramic green body;
[0046] S3, heating the ceramic body obtained in step S2 to 700° C. under an air atmosphere at 10° C. / min for 4 hours to obtain a ceramic pr...
Embodiment 2
[0051] A forsterite-based foam ceramic for carbon sequestration and a preparation method thereof, comprising the following steps:
[0052] S1, 100 parts of forsterite powder, 3 parts of bauxite powder, 5 parts of albite powder, 2 parts of potassium oxide powder and 4 parts of sodium oxide powder are uniformly mixed for 0.5h to obtain the main ingredient, while the carboxymethyl methacrylate that accounts for 6wt% of the main ingredient is mixed Base cellulose, 3wt% of sodium dodecylbenzenesulfonate and 85wt% of deionized water are mixed into an additive solution; the additive solution is poured into the main material and mixed for 2 hours to obtain a ceramic slurry;
[0053] S2. Immerse the polyurethane foam template into the ceramic slurry in step S1, take out and squeeze the excess slurry; and then dry the template at 70° C. for 6 hours to obtain a ceramic green body;
[0054] S3, heating the ceramic body obtained in step S2 to 850° C. under an air atmosphere at 15° C. / min f...
Embodiment 3
[0059] A forsterite-based foam ceramic for carbon sequestration and a preparation method thereof, comprising the following steps:
[0060] S1, 100 parts of forsterite powder, 1 part of dolomite, 9 parts of kaolin powder and 5 parts of boron oxide powder are uniformly mixed for 0.5h to obtain the main material, and at the same time, 4wt% of carboxymethyl cellulose, 1.5wt% of Sodium dodecyl benzene sulfonate and 78wt% deionized water are mixed into an additive solution; the additive solution is poured into the main material and mixed for 2 hours to obtain a ceramic slurry;
[0061] S2. Immerse the polyurethane foam template into the ceramic slurry in step S1, take out and squeeze the excess slurry; and then dry the template at 75° C. for 8 hours to obtain a ceramic green body;
[0062] S3, heating the ceramic body obtained in step S2 to 900° C. under an air atmosphere at 20° C. / min for 2 hours to obtain a ceramic pre-sintered body.
[0063] S4, uniformly mixing 28 parts of sili...
