Gas-solid separation ceramic material and preparation method thereof

[0026] (1) Preparation of raw materials

[0027] Add 5g of polyacrylamide into 5L of water to prepare an aqueous fiber dispersant solution with a mass concentration of 1g / L;

[0028] Mix 21g of kaolin, 4.5g of calcium oxide, 4.5g of magnesium oxide, and 70g of aluminum silicate fiber at a solid-to-liquid weight ratio of 1:50, then add them to the aqueous fiber dispersant solution, mix and stir evenly to obtain a slurry;

[0029] (2) Sample molding and firing

[0030] Connect the connection hole on the cylindrical porous metal outer mold (inner diameter = 127mm) with the liquid storage tank and the vacuum pump, and the inner mold (inner diameter = 71mm, wall thickness = 2mm, height = 700mm) is placed in the outer mold, and the openings of the two The end is sealed by the flange edge, and at the same time, a 100-mesh stainless steel filter is spread on the inner wall of the porous metal inner mold, and then the mixed slurry is slowly injected into the porous metal inner mold; th
