Preparation method of rare earth ceramic foam filter
The invention belongs to the technical field of a preparation method of a ceramic filter for casting and relates to a preparation method of a rare earth ceramic foam filter. The preparation method comprises the following steps of preparing ceramic pulp: mixing rare earth, ceramic aggregate and an adhesive in parts by weight to prepare ceramic pulp A and ceramic pulp B; preparing a blank: dipping a polyurethane foam carrier into the ceramic pulp A, sufficiently absorbing the ceramic pulp A, carrying out roll forming via roll forming equipment to prepare the blank, reinforcing the upper surface, the lower surface and a core of the blank twice via glazing equipment after drying the blank; and carrying out high-temperature sintering: putting the blank after twice reinforcing and drying into a high-temperature sintering furnace for sintering to form the rare earth ceramic foam filter. A sintering period is short; the energy is saved; the breakage of the blank is avoided; at the same time, the pulp is adhered more uniformly; the blank is reinforced twice via glazing; the internal pulp is distributed uniformly and has low possibility of falling-off; and the property of a sintered product is stable.
