Embodiment 1
[0055] The present embodiment provides a ceramic molding method, comprising the following steps:
[0056] (1) Weigh 29.12 g of polyacrylic acid amine and 12.48 g of Isobam104, add 960 g of deionized water and stir to dissolve, then pour into a ball mill stirring tank, reduce the rotational speed to 50 r / min after ball milling at 200 r / min for 10 min, and add 100 g of alumina After the ceramic powder is uniformly dispersed, continue to add 100g of alumina ceramic powder, repeat the operation until all 4160g of alumina ceramic powder is uniformly dispersed, increase the speed to 200r / min, stir for 1h, and then pour the slurry into the vacuum stirring tank Vacuum degassing was carried out for 20 min in the process to obtain alumina ceramic slurry with a solid content of 54 vol% and a viscosity of 0.4 Pa·S at room temperature;
[0057] (2) The bottom plate of the mold is a ceramic flat membrane with a pore size of 0.1 mm (the ceramic flat membrane support and filter layer are made...
Embodiment 2
[0065] The present embodiment provides a ceramic molding method, comprising the following steps:
[0066] (1) Weigh 11.2 g of polyacrylic acid amine and 2.24 g of Isobam104, add 220 g of deionized water and stir to dissolve, then pour into a ball mill stirring tank, reduce the speed to 100 r / min after ball milling at 250 r / min for 10 min, and add 100 g of alumina After the ceramic powder is uniformly dispersed, continue to add 100g alumina ceramic powder, repeat the operation until all 1120g alumina ceramic powder is uniformly dispersed, increase the speed to 250r / min, stir for 1h, and then pour the slurry into the vacuum stirring tank Vacuum degassing was carried out for 15 min in the process to obtain an alumina ceramic slurry with a solid content of 56 vol% and a viscosity of 0.5 Pa·S at room temperature;
[0067] (2) The bottom plate of the mold is a ceramic flat membrane with a pore size of 0.1 mm (the ceramic flat membrane support and filter layer are made of alumina cer...
Embodiment 3
[0073] The present embodiment provides a ceramic molding method, comprising the following steps:
[0074] (1) Weigh 24g of polyacrylic acid amine and 30g of Isobam104, add 1000g of deionized water and stir to dissolve, then pour it into a ball mill stirring tank, reduce the rotational speed to 30r / min after ball milling at 150r / min for 20min, and add 150g of zirconia ceramic powder After uniform dispersion, continue to add 150g zirconia ceramic powder, repeat the operation until all 6000g zirconia ceramic powder is uniformly dispersed, increase the speed to 150r / min, stir for 1.5h, and then pour the slurry into the vacuum stirring kettle Carry out 30min vacuum degassing to obtain zirconia ceramic slurry with a solid content of 50vol% and a viscosity of 0.2Pa·S at room temperature;
[0075] (2) The bottom plate of the mold is a ceramic flat membrane with a pore size of 0.1 mm (the ceramic flat membrane support and filter layer are made of zirconia ceramics), and the side walls ...
